Silvertone 1485. About to do a full restoration of this amp… lots more to come of this one. It needs a new OT (there are two in the amp), new power tubes, new pilot light, new supply caps and sundry other small parts, and a grounded power cord. The owner has also opted to have speaker patch jacks added to replace the hardwired connection, which was falling apart. Overall, a great specimen, but a real rat’s nest to work on.
