I bought a late 70's Sanyo am/fm/cassette/turntable on eBay about 6 months ago. The guy who sold it to me cleaned and lubed to near perfection. It's in great condition and plays well.

Today I went to turn it down and when I touched the volume knob I felt a shock of static electricity. Ever since then one of the channels won't work. I initially thought it was the speaker, but i switched speaker cables and they both work on the one channel, but not the other.

Could static have done this? What would likely be the remedy?

Thanks in advance!!!!!!!!
