Re: Merlin's morphing Pentode/Ultralinear/Triode EF86

I've done this on a couple of amps now where the EF86 was used for the input and then the 2nd stage.

Re: Traynor Darkhorse 2W output

Does anybody know the specs of the output transformer, especially the primary impedance? I'm planning a similar power amp with switchable tubes, and I'm not sure which transformer to use. I've got a Heyboer with 6k6, an upgrade part for a Fender Blues Jr. Perfect for the two 6V6, but maybe too low f...

Re: Rat and big muff in the same enclosure

That way, you could make some money instead of spending it and end up with a smaller enclosure. For example, this is my TSD-91, a TS-9 and a SD-1 on one b...
