I've bought a 505-1 TT few weeks ago from ebay.
Everything seemed to work fine but first I had a problem with the cartridge (still alive) and now I'm having trouble with the Black RCA Plug / right channel.
So I was Thinking.
Everything works fine the first 10-20 minutes but after this time I can't hear anything but a soft noise from the right speaker and I need to shake the RCA cables to repair the situation but unfortunately this workaround does not always works. I've checked all the cables and they are OK, I've put some of lube on the bearings, I've checked the tonearm... can't figure out where is the problem.
Sometimes I need to turn-off my amp wait few seconds and restart it.
Any suggestion will be appreciated !!!
my amp is a brand new Denon + JBL es30ch speakers
