Hello All,
I am in the process of restoring a Beogram 8000 (USA model) and have done a capacitor replacement and reflowed the solder connections on the board to the power transformer and the other solder connections that are the usual likely suspects. The transformer is for T56 120V 60Hz 23 W. There is no indication of any power getting to the turntable unit. No lights or any movements when the buttons are pushed. The fuse is good and I have cleaned all the contacts on the key board. Can someone tell me how to safely test the transformer with a voltmeter? I am a novice so please dumb it down for me regarding where the probes should be inserted to check for power and if the transformer should be checked out of the unit disconnected from the circuit. I have spent quite a bit of time getting a beat up turntable to a very presentable place so would like to save this unit.
Thank you,
John
Did you remember to introduce the ground connection that gets lost when you replace the original C27?Did you check the fuse inside the transformer housing?
Voltage checks are done with a multimeter (AC Volt), the voltages can be found in the schematics.

Hello Martin,
Thank you for your reply and sorry for my late response. My computer decided to quit on me after my post, so I am using my iPad temporarily to email. I followed all of your directions which were excellent that came with your capacitor kit, including the ground wire but I will recheck everything. I checked the fuse with the continuity setting from my multimeter and it is good, as well as is the one on the board.
While I have resurrected two other Beogram 8000 turntables, I am not very good with schematics and even if I find the voltages I am not confident about where the probes should go in the circuit. If anyone can really dumb this down for me as to how to check it with a multimedia I would be very grateful. I can solder and follow directions but am not that good with trouble shooting electronics and reading or understanding schematics.
