A “Silverface” (with a “Blackface” replacement control panel) landed in the shop a couple of days ago. Well actually, we had to haul it up the steps, and down the steps into the shop! be tha tas it may, the amp shad some serious hum in the reverb and some microphonic behavior during the first two minutes of operation, after which it quieted down. But the amp seemed to lack clarity and clean headroom.
Well now, after some work, this beast is loud and clear, no more reverb hum, and no more microphonic behavior. Unfortunately, the weight of the amp is the same ! ;-)
This amp is owned by a Mr. CD Woodbury.
