    If you have a ceramics/ pottery supplier nearby it could be worth a look. Some of them carry supplies for electric kilns such as nichrome wire and probably some hi-temp adhesives. They would likely...

    In response to the original question, I've never dealt with them directly.

    I have bought a couple of sets off the rack at the music store for low-budget repairs and they seemed decent quality.

    That would certainly work although the 100mA H.T. is a bit of overkill especially with Hammond's conservative ratings. There are a few more in that series that would also work there; 60mA is...

    "Side question, when we build these amps with eyelets and hand wiring on the board, we use like 22 ga wire. How do you ensure that you get at least that on a PCB board trace?"

    Apart from the...

    Here's a Canadian source for the Fender replacement: https://nextgenguitars.ca/products/hammond-290ax-power-transformer.html

    It looks like a horizontal mount on the tube chart so it might fit...

    For some reason I thought it said 2x 6V6, but you're right it's single ended with a tremolo. I recently learned that the same transformer is listed for champ and princeton, which surprised me. That...

    A tweed Deluxe or Princeton Reverb unit would probably work although without the schematic it is hard to know how the voltages would compare. Also the mounting orientation may differ.

    A coat of shellac would probably protect the stamp from the lacquer. It makes a great barrier coat for spraying anyways. Dipping may have different results with being exposed to the solvent for a...

    I agree that refinishing is not the way to go. The easiest thing might be to get another body, either prefinished or finished to your specs, and then rebuild the guitar with that. That way you will...

    Thank you for clearing that up Hemholtz. I will just go with a resistor then.

    Thanks Tony, the resistor was my first thought but I was worried about adding extra load to the winding. Maybe it's not such a concern.

    Adding a 5v filament transformer would be the best solution,...

    Dropping filament voltage with diodes

    I have an old power transformer that I am using in a build. It has two filament windings (both 6.3v) and I would like to use one for a 5 volt rectifier. Searching around on this site I saw a...

    There are a bunch of Magnatone schematics in one of the Weber books, but I didn't see that name. Some of the prints are pretty bad but all the ones I looked at used separate mono jacks for the...

    How Tubes Work

    I just saw this in a local Kijiji classified ad for a Vox Valvetronix:

    "It's in perfect condition, it's a tube amp which means it runs the sound through a vacuum glass tube (that you can actually...

    I have one of these and a CHB-35A in the shop right now that I am working on (slowly.) I can post up the preamp changes I made sometime if it's any help to you. It will likely take a little while...

    This seems like a good time to speak in praise of the Mustang switching arrangement where each pickup has a 3-position slide switch that allows each pickup to be switched off or on in either phase. ...

    I was thinking the other day, have you tested the output transformer to find the impedance ratio? It occurred to me that maybe the primary on the schematic might be a misprint and perhaps it might...

    Another little thing that can get overlooked: sometimes string trees have a burr on the underside of the edges where the string can hang up. It's worth taking them off and making sure that the...

    The load refers to the fact that the amplifier is doing work in moving the speaker cone and thus the air. In order for this to happen efficiently the impedances need to be in the correct ratio such...

    Generally replacement is easy, especially if it is panel-mounted rather than PCB-mounted. Not sure what pot value or mounting type you need, but nextgenguitars.ca in Nepean has a decent selection if...

    I wonder if an iron (with a cloth over it) might do some good. I've never tried it but I find new uses for them all the time, only rarely involving clothes.

    The sun was my first thought though;...

    You could just use a screw of the same diameter with a fender washer and nut on the underside (with the chassis out.) Tightening it up should crush the pine down. Safer than using a hammer. Don't...
