GU-17 RF double tetrode PP tube amplifier

Input tube 6Н3П, splitter tube 6Н2П, power tube ГУ-17 for each channel, OT calculated for 8.7K, using 7 cm2 E+I core, 5Ц4С rectifier, used for both channels and CLCRC filter for each channel.
The schematic is not mine, I just modified it for my tubes.
This amp is hand made.
