I'm working on a Beogram 4002. I've replaced all the electrolytic capacitors and also the 4 large carbon resistors on the main board. Everything works, but now the relay that connects the signal from the tonearm has almost no delay in it after the tonearm drops. The relay closes long before the tonearm hits the record.
I know there is a variable resistor nearby to change the delay, but no matter where I set it I almost instantly fires.
I think this was working before with a 1-2 second delay and I'm scratching my head trying to figure out why replacing parts might cause this. I have two of these turntables, and they are both behaving like this!
Any ideas?
Did you fit a correct trimmer?1Mohm if I remember correctly.

Since I managed to screw both of them up, i figured it was a wrong component swap. Martin suggested wrong trimmers. Good suggestion, but I didn't swap those.. What I did find is that I had used the wrong capacitor next to the relay... I installed a 10uf 63V, but what you need is a 100uf 6V. Makes a big difference and the relay delay is back on both decks. I'll wear my reading glasses next time!
