Re: [ARSCLIST] [AMPEX] Loss of Lubricant and A- and B-winds

Hi Richard:

I have a Yamaha dual-well cassette deck that dubs at 3.75IPS. I have no idea
if you can tap an output somewhere because it dubs silently, without sending
signal to the output jacks. So you'd need to then transfer off the dub, on a
non-squeal cassette, at normal speed.

BIC used to make dual-speed standard-head decks back in the day but who
knows if a working specimen exists anymore.

Another idea might be to filter the squeal frequency out if it's narrow
enough and constant enough. I've never encountered this problem with
cassettes.
