About this listing
This amp was recently serviced by renouned Czech amp tech Jan Stehlik (I can provide detailed pdf service report with photos of before and after). All three transformers are original - 1) Triad 45249 output transformer (the same one which was used in 5F6-A Tweed Bassman), 2) Choke Schumacher 17th week of 1961, 3) Power transformer 110V Schumacher 17th week of 1961. Original Oxford 10K5 speakers - one has been reconed. They all play fine even in at high volume. The amp comes with non-original harmonic tremolo footswitch and padded cover. The amp is located near Prague, Czechia and I prefer personal pickup.Service report: 12.1.2026:1) replacement of all 7 filter caps - 2X TAD F&T Germany, 5X Atom Sprague USA2) replacement of 5 electrolytic caps in preamp on cathodes - Sprague USA3) replacement of 2 electrolytic caps in BIAS circuit - Sprague USA4) 4 yellow Astron caps replaced with replicas (see the photos), the original ones were leaky and are included in the sale.
