Hi Dave.

I've disassembled a couple of tube tape recorders, and the parts generally do make very nice low power amplifiers. What I find is that the OPTs are often quite small, usually resulting in an amp with not much deep bass, but beautiful clear mids and highs. Should work well along side a quick, punchy sub.

Valuation-wise your Roberts could be worth anywhere between $10 and $100 depending on condition and buyer desire. I recently sold an Akai (same manufacturer) about like it for $35 at a swap meet. Some of the later solid state Teacs and (what was their pro brand?) still sell for hundreds of dollars, but most of the older consumer stuff isn't worth much.

Since non-functioning tube amplified tape decks can often be had cheap or free I've been hoping to find a better use for the iron than "another low powered SE amplifier". It is the same issue many of us have experienced with small console amp OPTs. May try some experiments using a couple small OPTs in series, or possibly as plate chokes (again, in series). If anyone has any good ideas I'd like to hear them.
