Hello there,
I'm trying to repair a DT50 212 for a friend, the amp hums as soon as it is turned on. No sound seems to get through at all.
Now, I've taken a good look inside the unit and it strikes me that R23 and R24 on the tube/psu board seems to be missing. I can see that they have been there as the resistor legs are still in place. Could anyone tell me the values of these resistors?
The hum must somehow bleed through from the psu, but I will look into that at a later stage.
Thank you in advance.
