    Early SAE 2600 Main Filter Caps

    Personally, I liked the 10,000uf @ 160volt ones you can get. I see you can get a 15,000uf that looks size wise OK. I didn't notice much at all on the Digikey or Mouser sites. Aren't the originals like 2.50" x 4-1/8"......

    SAE MARK XXXIB distorted channel, then loud buzzing.

    All I can say is I used 2 wire with a shield, shield hooked to "ground" wire on one end only and not the pot end.

    SAE MARK XXXIB distorted channel, then loud buzzing.

    I have to be honest, I get an on/off switch but why mess with a “volume” control in it.

    SAE MARK XXXIB distorted channel, then loud buzzing.

    I’d stick to two prong like it has and if I were doing it I’d go hot on the fuse. Seen it either way though on various electronics.

    SAE Mark IM preamplifier

    I put some axial incandescent bulbs in which seem ok but some kind of led would probably be better long term.

    SAE Mark IM preamplifier

    Found what I did: I think one of the 1B’s I did had that set of transistors you mention above. Found the info on the 1B and I showed a 2N4036 not a 2N4026 along with the others you said plus a couple 2N4250’s.

    SAE Mark IM preamplifier

    Don’t recall the exact ones but did for the most part used the same ones. There were different versions of this that had “older” transistors but this one had newer ones so it was easier I recall.

    VSP Labs Trans Mos Gold Series amp measurements
