Head1962: Nice looking amps and I see some Hammond iron. The red amps have open frame trannis, what are they, OPTs and who makes them? We all have a different twist on life and builds but I would be casing the open frame stuff. In your case, because the amps are so nice, personally I think it detracts a bit.

After saying that they look like industrial controllers, I like the gutsy appearance. And 5EM7 driving other tubes???? Outta my league.

Here is the Paris schematic designed by Matt of Seattle. He also designed the Silver Dragon (300B) and two of the 4S series of single tube preamps. I'm about to build his 807 design. I don't think I posted Paris Duo (Paris monoblocks) so I'll do that next.

Note: The 820ohm resistor in the PS, make it 1.1K 5W.

Default SE pentode amplifier.

KT66 power tubes, the driver 6N8S or 6N9S.
2x8.5-watt output power. The full power frequency range 7 ... 60 000 Hz (-3 dB).
Sensitivity to these drivers, 1.4 and 0.4 volts.
