All ready to give away a very sweet sounding amp and speaker system to my sister and brother in law when I discovered one channel on one of the three sources not working at all.
Three pairs of RCA input each pair connected to a relay - I managed to desolder the 10 pin relay and replace it with a socket and a new relay but still no joy on the same input source. Relays are triggered by three way toggle switch on the front of the amp. Relays are TQ2 5V DPDT Type Form C

Output from the circuit board is the same pair of cables sharing a ground connection and L and R for all three relays. There's a couple of resistors and transistor on each relay - I don't understand why I only get one channel if the relay is working.
Any Ideas very welcome Pictures from Ali Express site with source relay board in the middle.
