JVC M70C MMS demo
This lovely specimen was purchased on eBay with only the tape deck working and a very low volume/bass issue when playing. Wouldn’t pick up any radio stations. Had a power issue as well with power being delivered to the box even with the power switch in the ‘off’ position.
After removing the leaf spring switch assembly I found it to be stuck together. After a quick spray with deoxit and some fiddling, the box was up and running beautifully.
