Caps in series??

[Chuck H]

Challenge to bob!

I took the time to research every thread in this whole saga. You've spent A LOT of money on this amp already. I'm offering an intelligently considered experiment which won't detriment the amp one bit and I'm offering it FOR FREE! You only need to pay shipping. Stop putting components into the amp. Stop taking components out of the amp. Everything you're doing is out of context at this point. What you're doing is a waste of time if the goal is the amps original tone. If you don't have what it takes to communicate accurately or comply with specific test requests and simple questions on this forum then it's time to put up or shut up. I'm right here.

[Tom Phillips]

Holy frustration Batman!
I'm just up the coast from DAB and offered to host him at my shop and take a look at the amp even before he sent it to Scott. I didn't get a bite. It would have been an easy day drive round trip. I'm starting to think this is all just a mind game. There are long delays between posts and replies that don't address the questions. I think I'll work on building a time machine. There is a better chance of a successful outcome than there is with reading these Bandmaster threads.

I first measured with black prob to ground and red to domino cap on Ohms Got DL...Them I put red prob on the 250cap it read on the normal channel 285.5Kohms ON the Tremolo channel it read 250.8k ohm..So the Domino caps do not do anything...

NO NO NO NO NO NO NO

YOU ARE DOING THIS ON PURPOSE

You can not be so stupid, I don't believe it, you are intelligent although sick, you spent 2 days trying to find some answer which seems to comply with what we are asking , yet not doing it, and keep the ball rolling.

The very simple measurement asked for is to put " black prob" on one end of so called Domino cap , and then "red prob" on the other end, set meter scale to 2000 or 20000 ohms and read the screen.
Then posting results here, of course.

Since I don't trust you , a picture showing the test would be even better.

NOTE: measure with the cap still soldered to the board eyelets, I anticipate that your next move will be to "innocently" post something like: "I measured resistance as you say and meter registered "DL" (whatever that means, probably "OL" ) ...... oh!! .... and to measure better I pulled the Domino cap and measured with it on the table" ...... or something else you can kludge to obscure the original "cap with a wire across it" statement and keep avoiding a conclusive answer.

I tried to see where the 220 plate resistors went to under the board I used the contuinty

So NOW, to check a connection under the board, what has been in doubt since Day 1 and you still don't answer, you magically learnt how to use "contuinty".
Nice, huh?
Am I the only one seeing a consistent intent to deceive here?
Doubt so, by now it's clear that you are a Troll faking a dumb guy.

Wow, I guess you would even go so far as to use some nickname which hinted at your being actually dumb.
I wonder ....... I wonder ......

Trolling 101 anybody?

and it goes to the 250 cap..I will put one of the 220(R) back in and see how it sounds...

Maybe you mean 220k
With your carefully worded "poor writing" now you try to divide the board, half will read "220r but assume you meant 220k and answer accordingly, throwing all kinds of theories and deductions on the table.
Then after 223 fun filled posts you will pull the rug under their feet and claim that you *actually* meant 220r .
Or viceversa, let them accept the 220r at face value .... 223 posts yada yada yada ... and then state that you were talking 220k all the time.

You can twist data and rules at will, as long as some respected Forum Member falls for it and keeps answering , maybe for years.

Hey!!!! it's been at least 2 years , unless I'm mistaken.

The Amp works great..All preamp tubes are RCA,but I only have one worn out pair of RCA 6L6GC,

Who asked this? .... irrelevant.

so I am useing Tung Sol 6L6gc

Who asked this? .... irrelevant.

They do not have as much kick as the RCA,but I like more than JJ's...

Who asked this? .... irrelevant.

Why did Fender put the extra 220 plate (R) in anyway?

Second time you type 220(R) so this is not a typo, you are doing this on purpose.
To boot, you are trying to start a new conversation based on the resistors.
ANSWER THE SHORTED OR NOT DOMINO CAP QUESTION FIRST

Both Transformers are dated Sept 1963...DAB

Who asked this? .... irrelevant.

Of course, all these irrelevant questions would have started all kinds of overheated discussions with hundreds of posts at TGP, MY LesPaul, Harmony Central, DIY Audio, etc.
Tungsol vs RCA vs JJ?
any day of the week

Are you trying to contaminate this Forum?

Looks so.

Juan is starting to sway me Dumb Ass Bob. Put up or shut up x2.

[dumbassbob]

the 350pf cap is sorted Does nothing the (2) 220 plate resistors go to the 250cap....The amp works perfect,Only I could use some RCA 6L6GC..Thanks

So when you measured resistance across the 350pf cap it read "Does Nothing" on your meter? So we never figured out the answer to the question posed as the title of this thread, "Caps in Series??".

[Chuck H]

I know this will be as Juan predicted (just letting you know that you don't need to call me on it ) but I'll bite.

220 plate resistors go to the 250cap...

Which end of the cap?

If the "220" resistors go to the junction of the "250cap" and the 100k slope resistor then there is a 220k and a 100k resistor in parallel as a plate load. If the "220" resistors go to the junction of the "250cap" and the treble pot there is a DC path to ground through the tone pots. Neither of these is likely to be the intended circuit for the "220" resistor. You have almost certainly reinstalled them differently than the circuit GW pulled. You are getting further from your goal. Not closer to it.

[J M Fahey]

NO NO NO NO NO NO NO

YOU ARE DOING THIS ON PURPOSE ... AGAIN

You can not be so stupid, I don't believe it, you are intelligent although sick, you spent 1 day trying to find some answer which seems to comply with what we are asking , yet not doing it, and keep the ball rolling.

the 350pf cap is sorted

What does "sorted" mean?
YOU_CAN_NOT HAVE TYPOS ***ONLY*** ON THE WORDS THAT THROW CONFUSION AND NOWHERE ELSE
Do I see a pattern here?

Does nothing

Please tell me the brand of your Multimeter_cum_Spice_analyzer which tells you the *function* and *action* of a part.
You must have the Free/Demo version though because everything works except displaying the part *value* .
Like those demo PCB design packages which do everything, except Print or Save.

the (2) 220 plate resistors

AGAIN ... what the heck does 220 mean?
In any other thread we'd all think it a typo and *assume* a value ... not here.
Speaking with you is the same as walking a minefield, and nothing is "innocent".

Sir, I despise you for all the wasted time and brainpower, waste of good intentions and karma created by you in this Forum.

We all might be helping somebody with a REAL problem and much more deserving of our help than you.
Or at least chatting about pot lubricants, shafts and tremolo settings

Or Obamacare vs Putincare or anything else.

I for one, have just finished my morning coffee, which is a time I usually spend browsing this beautiful Forum, but have a lot of paid work to do and in the time I wasted writing this might have read some 20/30 posts, actually all posted since yesterday.

Now?
You wasted my free time, I'm going to cut/bend/paint/punch/silkscreen some 15 front panels (and matching back panels too) , really quite pissed off by this useless time wasted on a sick guy.

go to the 250cap....

AGAIN ... what the heck does 250 mean?
Anywhere else I'd assume a value, not with you, not again.

The amp works perfect,

WHO cares?
Somebody asked that?

Only I could use some RCA 6L6GC..

WHO cares?
Somebody asked that?

Thanks

Coming from you, you're not welcome. <-- not a typo.


PS: by the way, you have NOT ANSWERED YET the original question: is the 350pF cap shorted or not?
What is the actual resistance value measured across it?

Not that I expect a straight answer

[Chuck H]

I think Bob has actually answered the inquiry. Albeit indirectly since what you asked for was a meter reading and NEVER got one. But Bob was pretty clear several times.

...the 350pf has a wire running parallel with it... Years ago someone put the 350pf on top of the wire going to the 250pf to tone pot on my 63 bandmaster...

...there is a wire under the board going to the 250 pf cap... someone put a 350pf sm cap over that wire years ago...

...But someone yrs ago put the dommino cap across the bare wire going to the 250 pf cap... The bre wire under the board going to the 250 cap is hooked up...

At that point where the dotted line is going under the board..There is a 350pf dommino cap going over that wire to the 250pf The wire under is connected...

So BOTH the under the board wire And the 350PF cap Are BOTH (piggyback) going to the 250PF cap...

Only mod was the domino cap that someone stuck on piggyback to the wire.

Again and again it's been stated that the cap is shorted by a wire. With this information I can surmise that the meter ohms reading across the 350pf domino cap is whatever the meter default at zero is. That's why I never focused on the meter reading request Bob wasn't directly addressing.

That theory holds water only if we assume that dumbass has some idea of what parallel even means or that he knows what he's doing at all. The only thing that has become apparent to me reading DAB threads is that he has no business opening up an amp, ever......period.

[Enzo]

Chuck, I do see what you are saying with all those examples, unfortunately all of them are ambiguous. he may well have meant the cap was soldered to the wire at both ends, but that is why we kept asking and asking for a direct reading of resistance AT THE TERMINALS of the cap. All we ever heard was across the wire, on top of the wire, at the point the wire goes under, and so on. All we wanted was a verification that the wire was still intact and was indeed soldered to the same points as the cap. We never got it. How many of these 70 posts could have been done without if that one simple resistance reading had been taken the first time it was asked for?

[Dave H]

by now it's clear that you are a Troll

And a very good one too, 72 and counting.

[J M Fahey]

Make that 73

Again and again it's been stated that the cap is shorted by a wire.

WHERE did you read that?

NONE of your examples says so.

Well I thought they all did. Regardless... He also says that "someone" put the 350pf cap "across the wire" years ago. In reality it is Bob that put the cap in "across the wire". Gerald weber removed those caps when he rewired the amp as a stock BF circuit (which likely included adding that wire) and Bob put the 350pf caps back where he thought they were, chasing the amps original tone. I have no way of knowing what the original circuit was, but I'd bet the 350pf caps weren't "across a wire" before Bob put them in that way.

Oh well.

Oh well.

And that's why it sounds just fine now (YAYYY!), like a Bandmaster should, instead of sort of wooly & missing its "point" as that Tremolux I encountered did. All is well in Dana Point, let's go have a pint or three at the Coach House.

NOS RCA black plate 6L6GC's that's another story, going to cost a fortune. Maybe a good used pair, DAB can you put up a "wanted" post in Flea Market? Some may wish to argue... but I do hear a tone difference with these, and it's very nice indeed. A little extra warmth like =C= real Svetlana but the RCA's don't tend to get loose & microphonic at low frequencies & start to "moo" like =C= Svet's.

As for Russian made New Sensor distributed so-called "TungSol" I've had to heave too many of them in the rubbish whether labeled 5881 or 6L6, regardless of sellers' claims of "premium tone" or any other propaganda, when they arrive here they're rattling like maracas, me no likee, will not buy. Neither my crustomers nor I like rattlesnake-chatter noises accompanying every note. Sounds like a car with wheel bearings about ready to turn into dust. DAB, if that's what you got, I'm not much of a fan of those either, can you tell?

I'd rather have the original Sovtek wafer base "5881", good tough tubes that rarely give trouble, take a long long time to wear out. OK they're not RCA's but plenty affordable & sound just fine if you dial bias current up to 35-40 mA.
