If it could help to lead me further in repairing the amp myself: I remembered, that when I was disassembling the amp for changing the transistors, it was, of course, off the 220v outlet, but i somewhere short-circuited those big caps (on the line of power supply, I assume), and as they were still charged, they sparkled a bit. I didn't found exact

Hi, I need help again :(... I replaced potis and transistors (I used BDV67D instead of BDV65B, that was there originaly, but they are quite the same). Although, the voltage between measure points disappeared at all. It's 0.00... How could it be?!...
-
So, if I got you correctly, I firstly replace the potis, and if it doesn't help- the transistors TR1xx, yes?

It seems I need help again. I measured the DC voltage between those measure points you wrote (the same I found in the manual)- it's obvious that the problem is there, because between TP200 and TP201 there is almost 10 mV (~9,8), but between TP100 and TP101- ~78mV (!). The problem is that turning those potis doesn't influence those values at

Whow, at last something to try! I definatelly will do it in weekend. Will let you know the results!
-
Can you explain more about those trimmers?
-
Yes, it becomes quite warm in minutes the like you sugested...
-
No, the speakers are ok, i tried another pair and even checked the impedance.

Hi, my Beomaster 5000 started to behave like that: once i turn it on, it sends a big POP sound to loudspeakers and immediately turns itself off. What's going on? If I disconect the loudspeakers, it works- display and etc.
