Gone.

Big Bertha..........Quantity 2 monoblock channels, one common power supply OTL amp. Designed in the early 90s. One chassis shown representing both channels. Great for a do it yourself tweek to your liking or for parts. As is but should work. I will consider any and all offers, just do not wish to destroy it.
Similar to Futterman design.

Specs.

20 horizontal output tubes, 10 per channel. 6KN6 output, 12GN7A signal tubes. No bottom plates. Good for tweeking to your hearts desire. Pickup only.
Operation Triode mode.
When new 160 watts RMS, approx. 0,4% distortion. Last time I checked 120 watts RMS into 4 ohms. I have seen tubes for $20.00/ea.
High voltage power supply 360 volts, 5,000uf. Regulated HV supply.
Filament toroid transformers, dual 6.3 volt windings @ 20 amps each winding.
Capacitor output coupling.

Amp will be pitched, destroyed sometime this week if no one wants it. Just depends upon when the "man" stops by to
pick up the garbage.

I thought OTL amps similar to Futterman were sought after. Guess not.
