I've never done a guitar amp but havig built/re-built several audio amps I can say that most are pretty straight forward. Of course, isolation transformers from other manufacturers will work just as well...
Euro wiring will be different (and is explained on Step 7. A larger isolation transformer might nullify the problem, but when using the N68X the best solution is to rectify twice -- once with a solid-state bridge rectifier to shift the negative voltage over to positive; then rectify again with the 35W4 tube. Probably helps a bit. QuoteGood tone isn't very useful to dead musicians. I love the old Danelectro stuff. Isolation transformer for silvertone amp in case of computer. All the tube filaments are still connected in series, so removing the 35W4 would have created a new problem--how to drop the voltage on the series string of filaments (the remaining two tubes) by an additional 35V.

I'm hoping for a check-list kind of guide or rules set or possible scenarios. But if you touch the amp's hot and neutral wires you will still get shocked but the amperage is limited to what the isolation transformer can pass which is still enough to kill you many times over. Note the 'reverse peak' pickguard.
2Vrms input sensitivity for full output -- and on the other half with the power inlet -- 3. And many were built. If your amp has only one transformer (the output transformer) the answer is YES, you need one. Concluded it is not safe for me to buy a vintage amp for home use.
The smaller one could use this upgrade: However, I seldom use it, and I installed a modern plug that can't be inserted wrong, so as long as the outlet is wired right, it is safe.
