Details:

The circuit is based on the very expensive kondo (audionote) M77 model

Tube preamplifier, compatible with Phono amplifier. The Phono amplifier part can be closed under independent control

Tube model: 6X4 (ez90) * 1, 12AY7 (6072) * 8

TRW and GOOD-ALL bakelite sealed coupling capacitors and gold-plated electronic tube sockets are used for signal channels

It is designed to turn off the Phono amplifier function independently, switch the signal of 4-channel relay, and reserve a way to add chokes by yourself

PCB size: 220 * 290 MM

Transformer voltage:
AC250V~0~ AC250V@100mA
0~ AC12.6V@3A
0~ 6.3V@2A

Gold-plated PCB on both sides

HiFi audio resistors and capacitors components.

Note：

Assembled Board： has been assembled and tested as OK. excluding all tubes

Diy Kit : Complete kit, excluding all tubes. You need to assemble and weld by yourself.
