Different types of transistors can be used, AC126 is possible. I seem to remember that the first transistor is closest to the nearest outer corners of the amp. board. The service manual will tell you which one(s). It's possible that the same fault is present in both channels but of course, it could also be caused by something else. Is the static

Jeg går ud fra, at alle transport-skruer osv. er klart. Det lyder som om den er kommet ud af sin mekaniske sekvens. Den må nok til service. Martin

Wow, good job ! Swap the leads to the speakers to see if it's a speaker fault or listen carefully as you power on/off the Beomaster or switch channels for a thumb or any other sign of sound from the otherwise dead speaker. Check potentiometers, especially the balance potentiometer at the backside. It's often left unused for ages and will easily

I agree on the switches. Especially the ones that are only rarely used. Work them all a bit. Swap the speakers first to make sure that the problem is not with one of them. Martin

Looks to be a fine repair. Definitely sturdier than the plastic and I'm sure it will work fine. Good job, let's hear how it works once mounted. Martin

Det lyder mere som en pladespiller end en CD-spiller. Er der en plade på Beogram'en ? Den vil ikke starte uden plade. Martin

Me too. It's always interesting when a solution to a general and stubborn problem is found. Martin

Yes, that looks fine. Martin

Note that the 5-pin DIN pins are not sequentially numbered. Taking that into consideration, the leads seems correctly mounted. The two mains fuses are 250mA Slow-blow The dial lamp fuse is 1A Fast-blow Martin

Yes, and just added a bit to it as well. You need to check those leads against the servicemanual and make sure they are properly insulated. Martin
