This was the extraordinary amplification we used for our room at AXPONA - Check out our room review at part-time audiophile:
When we were looking to design an amplifier that could deliver the power of push pull designs and the sheer musicality of lower power single end designs, we settled for the 845 push pull combination and the Quartet was born.
The 845 only has a single grid so it can only be wired as a triode. This means we can't advertise this as a 90w amp in pentode or ultralinear mode. It does mean you will get the amazing soundstage that you expect from an 845 triode with plenty of power for most speakers. .
They are fitted with MKP capacitors and carbon film resistors. These amps also feature automatic biasing and have a solid state, twin choke, filtered power supply.
Feedback 6db switchable. Rectified dc heater supply with twin pye filters.
Auto bias set for 85 mA @ 750v. Solid state twin choke power supply.
