Accidental Sound, Can Someone Explain Why....

Tube Audio | Audiokarma Home Audio Stereo Discussion Forums - audiokarma.org
Hey Everyone...

Ok I've been troubleshooting a Telefunken 5216WK receiver/amp out of a Hymus Console. It has not been re-capped yet but will be once I figure out why there is no sound at all, it's actually been in this condition for almost 3 years. Ok here's what happened this evening. I had been taking some voltage readings along with checking resistors, well I accidentally left my Simpson 260 analog meter in the resistance setting and probed the 50uf leg of one of the electrolytic cans. When I did this I had music through one channel. You can see in the pic that I'm posting the can and the tab I probed, it has the 2 red wires along with a 390 ohm resistor attached to it. So my question is why would this cause it to produce sound? Oh by the way I did have a cd player hooked up to it, so it wasn't just music out of the blue coming through the speakers.lol! The pics will show the Simpson meter and the settings it was on. I don't have a schematic for this thing and for anyone who has worked on these German receivers know how tight things are underneath the chassis. I'll start a whole new thread in the next week or so when I really start digging in to this.

Thanks,
