I'm getting the BMC-220 from eBay. It has 2 batteries, no but charger. I have to plug it in with a 9.6v DC. How would I clean the heads? Like a normal VHS or Hi8 VCR? It has a strange head setup that allows it to record 2 fields with one head. Chamois swabs and 99% iso alochol? Or just get a Beta cleaning tape? It's record only and doesn't even have FF/RW functions.
