Magnatone M-197-3-M (Ray Meany) preset

Verified · 92/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Magnatone M-197-3-M is a tiny circa-1950 student amp from Magna Electronics, related to the Varsity M-197-3-V and sold as the Ray Meany model. Two inputs feed a single 6SJ7 pentode preamp, then one Volume control drives a cathode-biased, single-ended 6V6 into an 8-inch speaker, with a 5Y3 rectifier. With no tone control and one gain stage, it gives a simple, warm clean that breaks up softly when turned up.
