EAG AE782/A 1960 Full Tube amp Stereo MOD Final test 4X ECC83, 4X EL84



Published
This is an old Amplifier from the early 1960's and i modded it for stereo version. I rebuilt the main board PCB on it, but i used the original schematic for it. Uses 4XECC83 and 4XEL84 or E84L tubes. Its sounds amazing. It has one two way tone control for it, and you got 4 input what you can mix each other. Output transformers are the originals. The outher look is does not changed only the internal one channel got a pair for stereo. The Circuit is the same as the original but without the microphone input sections (2XEF86) and the main PCB draw again as i want. Power tubes can be adjusted with FIX Bias. The Power supply got a micro procressor controlled timer and checking the cathode current and if its too high the supply will be shut down.
The power tubes current is set about 27mA each. Supply voltage is 310V DC
