POWER TUBES used as PREAMP tubes? You can DO THAT?! Yes. We did. (Dr. Z Octal Six!)

The Doc brings us the latest in the line up: the Octal Six.
Power tubes as preamp tubes? Yes, we did that.

How? An quiet, powerful independent DC supply providing the juice for a pair of octal-base 6SN7 and 6SL7 tubes, traditionally found in smaller PAs and audio systems of the 50s, configured to produce silky, smooth clean tones and churning compression that tumbles into overdrive under your fingers.

Coupled with a high headroom 7591 power section and the punchy power of the a WGS G12 C/S speaker, these tones take the chunk and chime of 50s American-made amps and blast them into today, built on the 35+ years of experience here at Dr. Z amps.
