I have for sale my recently built '69 50W clone. The build used a Marstran chassis, Power transformer and Choke and uses a $errem Audio output transformer. Built with Mustards, Wima 0.68's, an bunch of Iskra's that I scraped up. It was built very similar to this thread http://forum.metroamp.com/viewtopic.php?f=24&t=39639. Pots are Bournes pots and the sockets are high-end ceramic/gold plated pins from Angela. The amp is quiet for it was built with the Larry Ground. SOLD
