National GAP-2 60's 2-Watt Solid State Combo Amp

Cool little solid state amp that used to sell in the Montgomery Wards stores. I believe this was made in Japan in the late '60s possibly '70s. It works as it should and gives a great distorted tone when cranked. Incredibly light and small, and has a two prong power cable.  At some point it lost its rear cover and has been replaced with a piece of cardboard. Message if you have any questions, thanks!
