A fresh restored EICO.
The output transformers were shot, so we installed a pair of brand new 35W Hammonds in place. The only items were original was the power transformer and two Ecaps, which still tested good. The rest of the old parts are all scrap and redone from scratch.
And here, we put this EL34 power amp from average good design to an exceptional high quality design (And in today's standard, not 50 years ago). We also installed a much better design into it with 12AX7 and 6SN7. Nothing much is original, instead, this is a pure hifi EL34 power amp. If you look at the power supply for example, its a much better design, with an additional high quality choke transformer in place (Made in Canada by Finale / Triode Lab), brand new better grades vintage styled ecaps (silver ones) in the front feeding the tubes. And to the EL34s, we have installed regulators on them to make sure each EL34 sees each same voltage - they will better / quieter / more accurate / sound better, as well wear out more even. It does not need to go this far, but we want the best being performed on this restoration.
Autobias. And measured 32W solid before distortion, easily 35W at max.
Perfect for those who are looking for a quality tube amplifier with some solid power and performance - and modern hifi output transformers and design. Its definitely not a looker due to the age, scratches/marks/glue here and there. But hey, anything at this level in a modern suits will costs 3-5X more!
Thanks for looking!
