AndersCRH Posted May 12, 2019 Share Posted May 12, 2019 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. -- Anders Quote Link to comment Share on other sites More sharing options...
psarkissian Posted May 13, 2019 Share Posted May 13, 2019 R23-24 are not related to the hum. There is a bigger issue there if the hum is that bad. There are multiple issues there. It needs to be taken to a Line 6 authorized service center. Quote Link to comment Share on other sites More sharing options...

It doesn't need to be taken to a service center, I'm quite capable of repairing it myself. Quote Link to comment Share on other sites More sharing options...
