Dear all, sorry for my writing in English, but I could not get any help on other forums and here I can see some specialists in Tandberg electronics.
My problem is: I have a TR-200 and I get the sound coming only from the left channel (A and B). I have checked the 4 big electrolytes, other smaller ones also seem to be OK. Output transistors (2N5496) and driver transistors (MPSU06/56) are also OK, I have checked only some resistors and they seem OK. I don't see any traces of burnt components, dry solder joints, bad connection etc.
I have cleaned and measured the balance potentiometer with my meter and it seems to be ok - when I turn the knob in the left position I get no sound from L channel, visa versa with the R channel.
I have swapped the cable from the preamp R channel to the L channel and I still get the sound from the R channel only. So, the problem is with the output stage, not with the preamp, correct? Is there any particular component I should check?
Thank you all and Happy New Year!
