This is a totally rebuilt tube PA head from the 70s.
It has four Hermansson channels, a tube-buffered effects loop, +600VDC plate voltage on the EL34, and a lot of tone-shaping features.
I rebuilt this amp the first time 10 years ago but have updated all channels now. Channels 3 and 4 have the Hermansson tightness control and two voicing switches per channel.
Channel 1: 2 gain stages
Channel 2: 3 gain stages
Channel 3: 4 gain stages
Channel 4: 5 gain stages
