Greetings folks - my first amp build thread. The victim is a 1948ish Webster-Chicago 66-1A wire recorder amp. 2x6V6 in PP, one 6N7 phase inverter, one 5Y3 rectifier, 8" speaker. W-C had 2 amps for their wire recorders, this is the smaller and mostly unloved one. The larger 166 model has a 10 inch speaker and a much more interesting circuit - apparently harp players like that one. This one has no preamp to speak of, and really doesn't make sense from a design point of view. 2 6V6 but only 10W. 10W but only one 8" speaker with a tiny voice coil. But on the other hand we have nice iron, a cool chassis, 1 vol, 1 tone, and 4 octal sockets to play with. My plan is to fill them with three 6SL7 preamp tubes and one 6SN7 output tube in push-pull for ~1-2 watts. A 5F1 would also work here but I personally feel like the world doesn't need any more Champs.
