Hi Fellows,
Maybe anyone from can solve this. On my Amateur radio Station during many years I've used a Interface Cable between my Transceiver Kenwood and my Heathkit SB200 HF amplifier. Last weekend during a contest the relay fault. The circuits consists with a OMRON 12VDC Relay,56KOhms and 2 NPN Transistors Darlington in Parallel. I've to replace by another relay . The problem I miss the conections from 56kOhms and 2 NPN parallel Transistors .
Anyone have any idea ?
please look at image BUFFER circuit
Thanking in advance for replying.
