Can someone fix my power supply Please.? I had my Quad amps serviced early this year and also sent my linn power supply to be checked and serviced as the resistors? at R1 and R2 were badly burnt.
When it arrived back the caps had been replaced and the burnt resistors.
Its been going ok now for 8 months but only with little use.
I switched on the other day and nothing, no light on the switch, just dead.
Removed the baseboard and it appears that the resistor has blown at R26. Im happy to pay the right person to check/update the board and to fix the problems. So can anyone help please?
 
Check the bridge fuse first. If R26 has blown then I expect Q3/Q4 output 2SC2501 devices will likely have died. C18 output capacitor might have gone leaky causing the failure. I'm just guesstimating from the schematic, my Valhalla has been fine for over 30yrs.
