High end

This stereo amplifier was build around 2 EL34 tubes, with a ECC85 phase shifter and EF80 preamp. Qualitative good parts were used, especially the interstage C’s are important to get the best results. Inspiration for me was the site of Triode Dick.


The mains transformer is put in the middle, surrounded by two small boards with a shoke and elco for stabilizing the high voltage for each channel.

The output transformers are from Lundahl, type LL1664 P-P (push pull).
