i still regret that my brains did allow me in high school and later in university to obtain ample knowledge of electronics and so keeping me away from easy ways to solve problems in faulty audio devices.
Consequently I have to address questions for help to forums like Beoworld's .
So here is one:
One of recently obtained beauties is a BM 1700 unveiling the usual problems with the tone- and bandselection sliders; I was very lucky to obtain, via the internet, replacements in impeccable state for these panels. After installing, the biggest problem was solved, but this action made audible that the balance was not yet OK. Inspection showed the situation on the powertrap; see picture. Measuring these 2 R's (0.39ohm should show on the multimeter, but they did not : one was short.
Inevitable question is: except replacing these 2 R's what other components that could have died and should be removed to be tested outside the pc board ( or maybe onboard)
