1963 Magnatone Panaramic Model 1210 Amp with "True" Vibrato

In this video, we will closely examine a mint 1963 Panaramic Model 1210 amp, made by Magnatone primarily for accordion use, but ideal for guitars. This amp closely resembles the Magnatone model 250 and 213, and has the famous "True" Vibrato effect. The circuit is analyzed, coupling caps and bias are checked, and the Vibrato circuit is explained verbally, then demonstrated both audibly and on the oscilloscope. In addition a brief discussion of the key components for this effect, the varistor, is provided. In the middle, for a break, we will visit the feral cats living inside (Jack & KC) and outside (Ollie, et al) of our house.....including a handsome newcomer with a cartoon character name.
