'Now you Can Afford Hi-Fidelity Audio'

A unique new 300B tube amp. The only 300B amp we know of that is driven succesfully by the musical EL-34 tubes. This allows for over 95% efficiency of the magical 300B tube and lets you drive even 86 dB efficient speakers. That is unheard of in 300B land !!!, where typical 92dB is the minimum with 95 dB strongly recommended. Visit your GF dealer today, to hear what may become the standard in 300B amps.
