Help with Bosch 48
#30

Quote:Morzh, its the resistor that goes to b+(5). Right now its 2200 ohms and 10 watts but its roasting.
I wouldn't run it too long with that resistor getting so hot, you're apt to burn something else up because someting is drawing too much current. Is it part of R11? If so could you post a pic of the original resistor? If it is a candohm style one or more sections might be shorted to ground.... they are known to do that, so it is wise to replace all sections at once. Otherwise you need to find out why the resistor is drawing so much current. I take it you have already replaced the original? And that was because it was open?

I'd also measure that transformer you put it in backwards and make sure both sections are OK. Can you tell us exactly which transformer it was? And did you replace it with an original or ???
