    Have you called Fender? They have always been good to me about giving me whatever schematics they have.

    The HDR100 is supplying 25V to both A and B circuits, right? So you can power up everything except the power transistors (which come off of the J101,J202 AC lines). If you leave J101 and J202...

    So HDR100 is the AC for your +/-25V supply and J202 is the AC for the +/-40V supply, right? When you have only one of them hooked up your bulb is dim, but if you hook them both up it is bright,...

    Most testers use a very small voltage to test the transistor junctions, like 5V, and it is possible to have a transistor that seems OK at low voltages and then behaves differently in circuit. In...

    Was the bulb bright, or bright-ish, when they were getting warm? If the bulb is glowing and the transistors are getting warm I would say that they are suspect. To quote something said often by the...

    Agree. I would also check the voltage rails for the op amps and the power amp.

    Generally, yes. As I understand it the magic of the light bulb is that its resistance goes up when it gets hot, so when current is high most of the voltage drops across the bulb. Depending on the...

    I've done worse. I would focus on voltage rails from the power supply, especially if it is a separate board. Unplug whatever you can, and if you have a variac and/or light bulb limiter use those to...

    Was it made by Bell Labs or is it a bell ringer (or bell tower) amplifier? Google tells me that Verdin is a bell, carillion, and organ company. Seems many of their amplifiers were made by McIntosh.

    Possibly. I am just wondering if the design that you bought led you astray on the fretboard height.

    I might be misunderstanding but it seems like this is is not right. The fretboard should sit up higher than the body. Here is a picture of a 4001 neck joint that I borrowed off Reverb. If your...

    I've had that happen with my Peavey Triumph, IIRC on that one there are some noise reduction diodes on the gain channel.

    Yeah, that one didn't change anything when I tried it. I was hoping there was some known issue with the mute circuitry.

    This is what the output waveform looked like on the drive channel. If you worked in the contour you...

    Actually in looking I'm not sure where I even got the 1-2 seconds. Maybe from some website. The 6L6 tubes definitely come up much quicker than the 6550s.

    OK, think I got this somewhat figured out. It seems like the 6550 types take considerably longer for the filaments to heat up enough to conduct. Instead of the 1-2 seconds the manual recommends it...
