Silvertone 1485. This is the model made famous by Jack White, with the 6x10 cabinet and the head that tucks inside. This was a full vintage restoration job plus mods for Ben from the band Restorations.
The amp is a weird design. It has two separate push/pull output stages with two 6L6s each. So there are two output transformers, each of which drives 3 speakers out of the 6. Both output stages are fed from a mix of both input channels, so there’s no way to do stereo. One of the OTs was blown in this amp and had to be replaced, along with all the original Silvertone-branded 6L6s. All but one of the preamp tubes were good and stayed put. Most importantly, the reverb and trem are working well; only the reverb driver stage was blown and it was easy to repair. The reverb itself is radically different from a usual Fender design; there’s no transformer and the transducer is a piezo element driven directly by a 6CG7 used as a push/pull long-tailed-pair.
The amp needed a bunch of other normal rehab work: grounded plug, disabled ground switch, all new supply caps, removal of leaky paper caps, grounding scheme updates, cleaned pots/contacts, replacement of drifted resistors. I cut the hardwired speaker connection and added two speaker jacks on the amp, and two on the cab.
