That turned out beautifully Steve and the Hammerite paint colour and execution of application to the tranny's is superb, really looks professional!SteveTheShadow wrote: ↑Sun Apr 05, 2020 11:25 am Like one or two others on here, I too have been at it with the DIY. I built myself a nice, 6W, single-ended KT77 valve amp out of bits I had lying around. No new bits were involved in this project. The blue transformers were painted with an old can of smooth Hammerite, I found in the cellar. The wood chassis housed the OTL. I just lifted out the OTL chassis after disconnecting it and dropped this one in its place.
It uses separate power supplies: one on the output stage, fed from the blue mains transformer, silver choke and large 5U4G rectifier valve at the rear right, and another, on the input stage, fed from the other blue mains transformer, and small EZ81 rectifier at front right. The choke for the input stage supply is under the hood, just behind the EZ81.
The pair of Genalex reissue KT77 pentodes are triode wired and fed by the pair of parallel strapped, 1960s, Hitachi 6SL7 twin triodes at the front. It partners the single driver Fane speakers nicely and gives a big, warm, detailed and musical presentation.
Jewel pilot lights look cool too, reminds me of my Fender Princeton guitar amp - knockout!
