Does anyone in the UK know where I can get a replacement Drive Belt for my
Mitsubishi B31 VCR?

Or even know if they are still available. Its an old machine but in mint
condition and working fine apart from the drive belt which is beginning to
occasionally slip and jump. Have tried cleaning the belt and pulley wheels
with Isopropyl but I think that the belt might have stretched a tad over the
years.

Thanks,
John
