Hi Mr. Devo,
I recall it from long ago, and agree with jjss49's assessment.
Refurbished Amber Series 70
I found one of these completely re-capped, re-biased, etc. for a good price. I think it’s one of the earliest versions (apparently they revised it a bunch over the production run). What would this sound like? I’ve never had a truly "vintage" amp, and this amp apparently has a minor cult following ...
