Lovely, lovely amp JJ 300B's ,EH 6SN7's and a Mullard rectifier,8ohm,16ohm version.
I have mounted it on a 5mm aluminium base damped on the underside with Acoustiblok and using Soundcare Superspikes .
£1300 pickup from Soton
info -
The pot you mention is technically a humpot, but it won't really function as one since both sides run on the same filament circuit. It was the simplest way to get a ground reference on the filament circuit
You can use any GZ34 or 5AR4 rectifier. If it's now got a Mullard, that's hard to beat.
it's about ten years old, one of the first with the direct coupled circuit. The output transformers are Magnequest DS025s, the power transformer a custom design and the plate chokes Hammond.
Wires connected to the binding posts inside the amp. Black is common oe negative (-), brown is four ohms, orange is eight ohms and yellow is sixteen ohms.
