    Enjoy your retirement, Enzo! You have certainly earned it! :) Your contribution to the DIY community over the years has been huge and very much appreciated.

    I found that raising the output impedance of a solid-state amp (irrespective of how it's done) gives better results with guitar speakers.

    The bass is boosted due to less damping of the speaker's...

    You could try the Magnatec BUZ901P and BUZ906P, I believe they are just about identical.

    The IRFP240/9240 can be used without flames, but it is not trivial, Rod Elliott explains how.

    I second the call for some sort of wheel or leg system that would enable the amp to run away when it sees a guitarist with a soldering iron. :)

    The transformer, rectifier etc. will certainly always get hotter with increasing output power. But above 40% output power the output transistors will start to cool down. This is a scientific fact...

    The whole point of the "E" series rectifiers is that the heater is well insulated from the cathode and can run off the same 6.3V winding as all the other tubes.

    This is in theory, in practice the...

    It's important to remember that the maximum dissipation in a Class-AB amp isn't when it's putting out its maximum output voltage. As you turn it down below clipping, it dissipates more, down to about...

    I like Reaper. You're supposed to buy a license for $60, but the free trial never expires, it just puts up a nag screen now and again. The plugins it ships with are very usable.

    The channel switching system could well be the culprit. A few people already suggested checking for dirty contacts on the footswitch jack. It wasn't clear whether you checked this. Connecting a...

    Yes. If the PCB designer didn't leave enough clearance between tracks that have a large voltage difference, the board material can break down. It looks like a little black spot in the PCB. Old Mesa...

    Sounds like you eliminated everything except carbonised spots in the circuit board, so time to look for those! :)

    You tried connecting the mics to your sound card via a capacitor. This is the right kind of idea, because capacitors pass high frequencies and block low ones.

    Unfortunately it won't work because...

    Taps on what? The wirewound resistor?

    I've used a 15 ohm sliding rheostat as an attenuator for years. I found it on Ebay for about $20. It seems to be made of iron wire and I guess the extra...

    The Unleash is just an attenuator with a line out, connected through a volume control to a solid-state power amp. The power amp happens to be Class-D but that isn't essential to the functioning of...

    Well, when you dump charge into a capacitor, the electric field aligns polarised molecules in the dielectric, storing more energy than if the dielectric were air. It's tempting to see this as the...

    I think it's to allow you more flexibility in driving it. Each speaker is 8 ohms, so you can connect them in parallel for 4, or series for 16, or drive them independently from the two channels of a...

    Easy. You lift the bottom ends of the 1 ohm resistors off ground and connect them to the OPT secondary taps.
