I'm curious if anyone (maybe the Doctor can chime in here) knows how the 1/2 power switch on the Remedy works. At first I thought it was shutting off two of the power tubes, but this would involve some pretty complex switching and a multi-tapped OT since it would mess with the impedances. It would also potentially lead to very uneven tube wear which might cause more servicing issues.
Now I'm thinking it's probably just a pentode-triode switch which would be simpler to achieve. My ears also seem to support this since I experience a noticeable drop in clarity when the amp is switched to 1/2 power (it just sounds more congested to me with less note-to-note definition, especially in chords). I also don't get quite the difference in headroom that I thought there would be between the two settings. Of course, that might simply be a psychoacoustic trick.
Anyone know the answer?

It does NOT shut off two tubes. The Doc may be able to explain it better...I just play the thing.

Hmm.. I seem to remember reading that at the 20W setting all the tubes still get current but the signal only comes from 2 instead of all 4. But I'm not an electrician, I only play one on TV. I'm curious to hear how the magic really happens.

I'm curious to hear how the magic really happens. This is basically it as I understand it. All the tubes are on and functioning even at half power. The signal for two of them is going to output in half power and the signal from the other two I believe is going straight to ground. It definitely is not a pentode triode switch and it doesn't disconnect two of the power tubes like the old 70s mod to 100 watt Marshalls and Twins. That means you are using all of the tubes up at the same rate and that the impedance doesn't change when in half power. Or at least that's how another non-electrician understands it.

All tubes on all the time, but signal through only two of them on half power. It's a fabulous design, made redundant with the MV - now mine stays on Full Power permanently
