Gentlemen, a new titan walks the heavens. No, the creek did not rise, exactly. The amp had passed the Rob and Sluckey in-build tests, and proceeded to pass safety ground, ohmmeter, and continuity testing, plenty-o-bias check, no-tube tests, rectifier-only tests, and then heater glow and voltage tests. Plugged in an old speaker (sitting in a box on the bench) and a guitar -- woohoo -- sound. Guitar sound, even. Since things looked good, I swapped out my 'R&D' JJ big tubes and beater minis and stuck in NOS. This was all with the NFB lifted, because easier. So of course when I clipped in the NFB, there was a faint howl -- like a toddler not getting a candy bar on the other side of the store -- as the amp warmed up. No deafening squeal, but present even with the volume on zero. So I switched the OT secondaries and bingo, clear, quiet, pretty sound. Voltages looked pretty good, mostly. But i knew that getting my bias set would change B+ and might take some iteration. Then it started to rain in the headwaters of that darn creek. As noted, I'd used Doug Hoffman's 'Princeton bias pot' setup. But I couldn't start to get the bias hot enough -- got as high as 14 or 17 mV when I wanted 22 to 25 or more. I'd used a 30k resistor to ground off the bias pot, using the original value from the bias board just like I did on my PR. Hmm, let's swap in 27k, a 'universal' Princeton value. Still not getting there, but better. Luckily, I'd been OCD enough to also order a 24k, and with that in there I have 'just enough' range to get in the 60-70% dispersion range. B+ is around 333, power tube plate-cathode voltage is 328, and I get 22 and 25mV on my 1-ohm resistors. So I put the real speaker in the real cab on the floor and plugged in to the chassis using a speaker extension cable... In the basement, heaven. Sustain and grit and chime and -- oh, nvm, this is a family-friendly website. But when I stuck it all together and got it upstairs -- total silence. Red lamp, no smells, no sparks, but no sound. How could putting the amp in the cab kill it? But I had one idea. Only one. Back in the basement I plugged in the speaker extension cable, which has a big, fat, full-length Switchcraft plug. The speaker in the amp has one of those great old-style right-angle plastic-cover Fender 'F' plugs. And when you lifted the cab up on the bench, and plugged that in directly, and looked at the shunt jack, it wasn't bent quite far enough to separate from the tip jack.. Two seconds with a bladed screwdriver, and bingo. Luckily for me I've seen this once before; in that case George L plugs wouldn't open the shunt on an input jack even though Switchcraft plugs would. So, what's she like? All of you who told me the 6G2 is the best but least-appreciated little amp out there were right. Not little, either, cuz the sound is hu-u-uge. Tele paradise -- that singing sustain you get in a tweed mixed with the beautiful highs in a blackface and balanced clear mids you don't get anywhere else in Fenderland. Sweet sweet breakup, a little even low on the dial if you dig in, a ton -- but so pretty -- as you go through the middle of the dial. Thanks to everyone for their kind remarks, support, and remarkable help and patience in my endless research and planning. You all share in the credit: This is an amazing amp. Oh, and did I tell you she's a blonde? A beautiful *rough* blonde? Note the dogbone and corner protectors. I think they lend her a bit of what I'm calling "Showman-ship." And the speaker CJ recommended? Somewhere between a Jensen C10R and a CTS ceramic from a SR. Yeah, she's all that! The nameplate? Turns out an amazingly generous friend has access to an industrial laser cutter, and went to a *ton* of care and effort to make it. Oh, and Pennington? a great little town not too far from... Princeton.
