Type 1: DIY FULL kit.
Type 2: DIY kit (not include all the Capacitors)
Type 3: Bare PCB ( with 8pcs tube socket + 6pcs relays + Signal switch + one connect cable)
Type 4: Full Assembeld board
Note: all of these opinio are not incldue tubes.
PCB are all Black color at present.
Introduction:
- This circuit is compatible with preamp and phono amp, and the phono amp part can be controlled independently.
- Recommended vacuum tubes(you need to prepare by yourself): 1*6X4(ez90) +8*12AY7(6072).
- The transformer and other components' parameter please read the below circuit.
- Adopting 2.4mm double gold-plated PCB, most resistors are original DALE and Philips brand.
- The phono function can be closed independently, 4-way relay to switch the signal, preset the function of adding the choke.
- Suitable machine case: whose front pannel with 3 knobs, standard size of (width)430mm*(inner height)70mm.
PCB Size: 290mm*220mm
Works voltage:
250V-0-250V ( 230V-280V are all ok. current about 100ma).
0-AC6.3V (Currect about 2A)
0-AC12.6V (Currect about 3A)
