This is a Leslie Reverb power amplifier that was used in the122-147-RV models. It has been sitting on my shelf for many years. I feel sure it was working when pulled. I plugged it in and all the tube lit up. No other testing was done. It is sold as is due to age. This one is gray color. I see people are making guitar amplifiers out of them. Shipping will be what is listed. The model is 016140 Thank you.  I will include copy of the schematic for you.
