  • Secondary PT voltages for 5150?

    Anyone know right off hand what the secondary transformer voltages and current ratings are for the original 5150 Peavey?
    And the 5150-II? I don't have one here to measure right now and I need to have someone make 4 transformers with 230volt primaries.

    I don't know offhand, I could infer them from the schematic, but I am sure you could do that too. I assume you have those schematics. As to currents, in my experience, PV transformers have always been robust. I have to change out a boatload of Marshall trannies for every PV one that fails.

    As far as I know that PT is the 70518727 for both those.

    If I needed that info, I;d contact curtomer service at the factory. Peavey has never been shy about helping folks, nor too sticky about keeping tech data too close to the vest. An inside tech guy like Gene Ford might be a good place to try, I THINK his addy is gene.ford@peavey.com. Roger Crimm is a CSR there who has always been helpful.

      Hi Enzo
      These are to replace 120 volt mains versions which are in proper operating condition. Few people buy Peavey products from the Russian distributor because they are very hostile to stores and customers, and of course will not allow any parts to leave their internal shop, and will not repair units out of warranty. I have spent a lot of time with emails with Peavey US, and the European parts center and head of sales for Europe including Russia. I am so tired of trying to crack that wall that prevents anyone from getting customer service. No one cares that the 2nd largest potential market is being thrown away.
      Peavey did not believe that the distributor will not cooperate, the head of European sales demanded written proof as if I was making it up. I finally was able to get a text email confirming what every musician in the country knows. I suggested instead of flying in, wining and dining with the upper management, and leaving, try going to a club or rehearsal hall and talk to musicians and see that sales are so low. He replied that sales are better than ever so he saw no problem, but he did not have a clue how big the market is and how average musicians are getting their gear. They are paying new prices for used units on eBay, usually not working by the time it gets here.
      Sales would explode for the first company that showed any desire for customer service. So far there is none that will support their gear or a treat stores or end users as anything less than the enemy.
      With the help of Peavey Europe, the distributor's parts department begrudgingly said they would get one of the last two remaining transformers in the European parts center in England but then started putting all sorts of road blocks, like saying I had to deposit xxxxx rubles in their bank account but they would not provide any invoice or receipt and they would not order it for a minimum of 3 months after that and would not ship it to me, I would have to get travel 1200 miles round trip to get it. Then they started getting unreasonable. But they did, after direct questions posed a dozen times, confirmed that they do no sell parts to anyone, in writing.

      But it is too late, I am encouraging every musician and rehearsal hall to boycott these companies, as if any suggestion would change things, they already refuse to buy or deal with these companies by the droves. Going to the distributor's stores is enlightening, no one is there except an occasional parent seeking a first time instrument purchase for a small child.
      In my little part time shop, I have 3 almost new reissue SVTs, a couple Fenders and Marshalls, a HiWatt and a couple Peavey's, and a large format digitial mixer, all needing parts that are coming from 3rd party sources around the world. They all paid top dollar for these, a used SVT reissue costs $3000-3500 here. A used beat Peavey Classic 30 costs more than a new one. So there is money being spent but just not with the manufacturer's distributors.

      Long story....but wanted to give a background as to why I need 3 or more 230v PT's and the schematic has no voltages. Just from memory I would guess 36 ct, 375v, 6.3v and 55v open circuit for the 5150-II but I needed spec so I could confidently order custom transformers to be wound. I also have two customers waiting for HiWatt transformers, one is a new unit, still under warranty purchased here but there is no repair facility here and the company in UK will not send parts here. It appears the Partridge QC has gone down a lot since I have seen several new or almost new HiWatts with bad transformers. I almost never saw bad transformers back home in the US.

      Thanks for Gene's address, hate to bother a bench tech. I have had lots of contacts with Roger over the years, one of the reasons Peavey has a great rep for customer service....in the US. Never really had to contact anyone for tech assistance except software issues with their first keyboards, since their gear tends to be straight forward and conventional in engineering terms.

      It is funny to note that my biggest frustration in moving to this country has been due to people outside the country.

        Gene is not just a bench tech, he is there as a support guy, he is someone a guy can call to ask for technical hand holding. Oh he won;t spend two months inching along like I do with some learners, but you can ask him tech questions. It is his job, you are not taking him from other duties. Well he IS a bench tech, he just isn;t there just to fix stuff all day.

        You already know this, but if you want transformer specs, it is not necessary to preface it with the back story when discussing with them.

        I am glad you know Roger. He's a good guy in my book.

          Yes, I don't get the people in the trenches involved with management or strategic problems, they get enough of the fallout.

          Thanks for the suggestions.

            It appears that there is a big market for used gear in your market? How do most folks deal with the difference in mains voltage - external transformer?
            You would think that this situation/environment would spawn Russian MI manufacturers?

              It is a potentially huge market but it is being completely blown by western companies. at least used gear sellers or agents are doing well. Typically, new gear is purchased by an agent in the US advertises the brands he can get....not a dealer, just a Russian ex-pat in the US. Some places an order and sends money by one of the web money handlers or WU and the unit is purchased and packed for shipment. It takes a month or more. The gear is often 120v 60hz only but that does not seem to bother the buyers too much. They use step down transformer but as I have pointed out to several, 60hz only transformer even if feed 120volts get a lot hotter running on 50hz. A typical 100 watt range tube amp like the 5150 that is so popular here with kids, in standby just under 1amp from the primary at 120volts when running on 50hz but 400ma when running on 60hz.. The difference is goes up in heating the 60hz power transformer. After 4 hours of running, they will fry an egg. That is why I see so many transformers fail here and replaced only a couple a year in a very high volume shop in the US.
              There are a few companies making pa amps and guitar amps here. One Yaroslav, sort of a cross between a 5150 and Riveria but more complex. Also there is a company here that primarily exports called Novik who makes a line called RedBear. They look pretty good, moderate priced, not as fancy or not as overly fancy as the Yaroslav. But people want western brands like older tube Fenders, Ampeg, Marshall, Peavey etc. If I had a good connection for checked out, decent used gear or even new store stock that is willing to ship here, there are a lot of fractional container consolidators. They take longer but heavy things are cheap to send in a container. Shipping a car in a container, filled with equipment costs no more $2000. When it gets here the car sells for twice what it does in the US, and the gear inside the car does not get charged by customs and is about $0.35 a lb to transport. Shipping an amp by UPS might be $200-350.
              What is REALLY needed is a parts source, a shop who has warranty status with a lot of brands who wants to place orders for $1000 a month or more with orders placed once a week, sent to me where I distributor it over the 11 time zones of the country. That single act would create a support infrastructure that does not exist and allow a hundred small start up shops to open. Imagine the incentive if you were the only one in your state who could get OEM parts, you would be opening a commercial repair shop immediately. A country much larger than the US, with no repair shops and millions of customers. By consolidating parts requests from dozens of small shops every week, shipping would suddenly be feasible. If I order a key for a keyboard now, which costs $5, it costs $75 to get it here. If the same key was in a USPS flat rate box with 10kg of 100 other small OEM parts, that ships for $75, suddenly it all makes economic sense.
              The transformer problem is likely only solved by finding a local transformer winder to build them. When I need a speaker reconed, they do not recone it, they wind a new VC because recone kits are not available. Other than transformers there are not many parts that weigh much so shipping in USPS EMS flat rate boxes up to 20 lbs is $79.95.
              Russian citizens can receive up to 1,000euros per month in value of imported personal items duty free so the parts boxes would be sent to one of a couple people who could each accept $15,000 in parts shipments a years duty free.
              As I mentioned in a prior post, if even one western brand took the market seriously and established some sort of customer service, they would own the market. How big? Well, there are 5,000,000 people with formal conservatory training in music, 100,000 active musicians in this one city alone, the largest cities in Europe, and young people with high levels of discretionary income.....yet none of the western brands know any of that or care and just assume sales are weak through their distributors because no one has the money to buy their products. An interesting note, there is reluctance to buy Chinese made items. Behringer does not sell well, they would rather spend more for imagined quality. When shopping for clothes or personal appliances, the first thing asked is "where was it made?". My GF is not extravagant at all but when shopping for clothes she would rather not buy anything if the only items that fit her or look nice on her from a store are low cost Chinese produced items. It is considered a bit on an insult to give a gift if it was made in China, but Korea is considered good.

                km6xz,
                Fascinating insite into the issues you have in the east. I thought we had a hard time in the UK with US suppliers and shipping costs
                I just checked the voltages on an early 5150 (assume you meant the head not the combo) and here are some specs under idle with HT on:
                bias purple-purple= 56vac one tap fused at F1A
                switching orange-CT-orange= 39vac both taps fused at F1A
                HT red-red=375vac 210mA at idle one tap fused at F2A
                Fil yellow-yellow=6.3vac (surprise!) one tap fused at F10A
                Sorry didnt measure all currents but the fuses are hopefully helpful.
                All the best, M

                  Thank you very much Metro, I really appreciate you taking the time to measure those. Since my post one studio brought in 3 5150s, one of them being a version II. These kids, all about 19-22, 3 partners, have a rehearsal studio with 15 rooms, 8 are all tube and the rest are solid-state. Most of the amps I get in are rehearsal studios because most bands rent space by the month due to almost everyone living in apartments in the city. So there are probably a hundred rehearsal halls in the city center. Given the high rent, I am surprised anyone can run a place with enough room for 15 rooms.
                  I am going to have a winder make a number of transformers for stock besides the ones already requested. One glimmer of hope, yesterday one company said they were happy to send parts if needed, Carvin. They have a distributor here but they only have one repair shop in Siberia and a chain of about 20 retail stores. Carvin said no problem going around the distributor, as long as customers got their amps worked on properly. I was working on a V3 at the time. I will encourage musicians to buy Carvin so their investment will be protected.
