In this video we take a look and a listen to a vintage Magnatone M-197-3-M lap steel 1x8" tube amp combo. This model is similar to their earlier Dickerson lap steel amps, although with some differences that we will discuss as we go over the schematic.
Here's a link to the schematic. You may have to like my Facebook page to see it. Not sure.
