    Unique Favorite Tools of ours

    I've been buying tools since I was ten years old. I grew up in a house with a basement, where my dad had his work shop, and my brother and I were eventually given shop space, our own work bench, and...

    Having found #6-32 x 3/8" SS Blk Truss Head machine screws, Philips at McMaster-Carr and ordered some, I've been trying to find the M3.5mm x 10 or 12mm Long Truss Head screws, either in Philips,...

    Now, the hard part is finding who still has them available for sale. I seem to recall that was an issue when I had tracked down the four pieces I bought. I don't think you can find them at...

    Major bummer. Sigh..................

    Well, you can get the xmfr dimensions, mounting foot print, and start searching for a similarly rated transformer. You should be able to find one that has...

    Switchcraft L(x)MN Retrofit Connector for replacing Amphenol MC4F mic output connector

    It's been a few years since I've bought the Switchcraft L3MN Male XLR connectors, but these were made to directly retrofit into any of the microphones that used these Amphenol MC4F connectors, which...
  6. Power & Rectifier Tube Hold-Down Clamps

    While I prefer this style of tube clamp to the different shapes of Bear Trap clamps, which all too often don't hold the tube well, and allow the power tubes hanging upside down in Fender combo amps...

    You might want to hold off selling off those 4722 input xfmrs until you're totally sure you have a failed power xfmr. There are 12 wires on the secondary side of the power xfmr, so make sure ALL of...
  8. Now that there's a schematic to refer to...

    Now that there's a schematic to refer to (assuming you didn't have one yet), notice that the Power Xfmr secondary has twelve wires to disconnect, to be certain there's not a load still present. I...
  9. Altec 342B Data Sheet, Operators-Service Doc & Input Xfmrs Doc attached

    While I did scan the Altec 342B Data Sheet, 342B Operators-Service Document & the brief Altec 4772 & 4665 Input Xfmr Information sheet, I see from the results, I'll have to go back to that copier and...

    So, you're now in Protect mode (hence, no HT voltages to run the preamp/power amp tubes. Now, very strange that one of your six screen resistors would blow under this condition. Or, did you just...

    I do miss the days of a multitude of Electronics stores in the LA area. Yale Radio on Sunset Blvd with Pacific Radio a couple blocks further east on Cahuenga, both catering to the Recording Studio...

    Always satisfying to find the amp went back together without a hitch. Not that I had planned on it taking me 17 bloody hours to get thru with all the details. When I first preset the bias levels...

    This is an dear old friend....the 342B. I had one back in the late 60's that our band's manager got from somebody. It only had two input xfmrs, but they were the 4665's rather than the 4722's,...

    After de-soldering and re-soldering the input tube V1 of the power amp chassis, then doing same with the plate, cathode resistors and coupling caps to the driver stage tubes, I no longer had the...

    Since I had run the tap thru all twelve standoffs, that solved that hex driver problem. I have both M3.5 taps as well as #6-32 taps, as Ampeg in the later production models changed to M3.5 hardware....

    I've found their 'relative' calibration VERY STABLE over the years. I did pick up a plugin extender which allows periodic adjustment of the vertical balance in the dual or single-trace plugins, but...

    I forget the details on the 7613. I have a R7623A and a 7633 (that one here in the shop), along with a couple 7834's...all storage scopes. Isn't the 7613 also a storage scope mainframe? I haven't...
  18. Sometimes just getting an Ampeg SVT-CL/AV/VR apart is a daunting task!

    This past Friday, I finally had completed the pending repairs on various combo amps, and finally got to the other Ampeg SVT that a client's driver had brought over for service. I had only briefly...

    I agree. The Mesa amps came to mind, where they use a lot of J175 P-Ch Switching Fets, that have -30V DG rating and 30V GS rating. Most of their usage is in the Grid section, though in one location...

    I rarely get more than a few sips from my freshly-poured Espresso (not brewed to real Espresso density....just like it as a rich flavored coffee), and invariably, what has gotten cold or luke warm...

    That's what I do in the shop. Cheap & maintained $20 Hamilton-Beech coffee maker, Krups bean grinder, and Trader Joes Five Countries Espresso Beans. But, at the other building, somebody else is...

    When I catch a check-out clerk grab the 1 gal jug of water with the molded handle and try and slip it into a plastic bag, I just eyeball them and ask what it is they think they're doing? Is that how...

    I've never stopped to talley up what it costs for a cup of coffee using those pre-packaged disposable containers vs ground coffee, or beans & grind them as needed, which is what I do. I'm sure those...

    This one is about as close to the '87 LE as I have in my files. I have what looks like it was a photocopy attached to the roof of the cabinet. As we all have had to do over the years, find the...

    This was the first time I've had to pack up and leave. I trade 20 hrs of labor for the shop space every month. When there's no work in a given month, that has put the financial squeeze on me big...

    It was acoustical. I did play with position of the tank installed in the pouch without any real change. I didn't think to try inverting the tank. I did at least add some foam padding between that...
