QUARTET MONO BLOCKS
50 watt 845 push pull mono block amplifier
When we were looking for an amplifier to fit between the power of push pull designs and the sheer musicality of lower power single end designs, we settled for the 845 push pull combination.
Having the look of our Carissa it has the power of the Concerto and the high frequency extension of the 300b.
Fitted with MKP capacitors and carbon film resistors with automatic biasing with a solid state twin choke filtered power supply.
Split bobbin multi section output transformers.
Feedback 6 to 9db switchable low and high.
Rectified dc heater supply with twin pye filters.
Auto bias set for 85 mA @ 750v
Solid state twin choke power supply
