parallel push pull (PPP) amplifier with 829
the big member of my tube amplifier family.Power: 70W rms(8ohm)
uses two (4 pentodes per channel) 829B in parallel push pull topology.A very difficult project than took me 2 years!!Uses 12au7 as preamplifier, 12sn7 as phase splitter.The power supply uses OA2 , to have 150v dc at screen filament (G2).
