Seeburg auto speed

Hi Group,
I have an LPC-480 that the carriage won't move. One of the SCR's that
forms the bridge in the auto speed unit is toasty and tests bad. (I
have Zero volts at the test point) Where can I find these? John
Robertson's site crosses these as a 1n1488, but neither Mouser or
Digikey have them. Any ideas? Also, a bad motor run cap could cause no
voltage ,correct? Thanks for any input.

First off, the autospeed only comes in when the record is clamped... it runs
native at 33rpm in scan.

No SCRs in that puppy, just diodes... and transistors.

Every Autospeed I've repaired needed a new run cap.. they're about six bucks
at your local motor repair shop, and don't let them test the old one, the
testers lie.

Cheers,

Don
