These both have the preferred dual 5Y3 rectifiers (the other version uses a 5U4 rectifier). All of the tubes are included, each amp has..
These are perfectly suited for stereo as dual mono amps or for use as two separate lead, rhythm or bass guitar amps! The front panels have separate volume controls for each input (MIC 1, MIC 2 & PHONO) and a separate bass and treble control. The back panel has an electric receptacle, two speaker output sockets, plus a 5 screw speaker terminal strip with a wire that allows you to choose COM, 4, 8, or 16 ohm speakers. There's also an RCA type input plug on each for Phono or CD connection.
Both still look to have most of their original components, both amps were bought at an estate sale several years back and have been sitting in dry storage so you may or may not need new tubes and are not guaranteed but I will guarantee the power transformers not to be DOA. The chassis and cages of both amps are also in great condition for their age with no rust at all and just a few minor age related scratches please see pictures.The cages are slightly different and present on both amps, one of the power cords is missing as is one of the bottom plates. Each measures approximately 14 1/4" x 8 1 4" x 6 1/2 and weigh about 23 lbs. I bring all tube amplifiers up to power slowly on a variac with a full load to avoid damage and properly reform the capacitors. Although I test them to the best of my ability, I'm not an expert by any means!
We may not be able to test all functions, some may have been repaired or worked on, some functions may or may not work and there may be damaged components that we are unable to determine and need additional repairs. Some items will just be plugged in and powered on without further testing so don't assume the item works because it powers on. When purchasing 50+ year old items you should expect that some work may need to be done to them to bring them back up to their full potential...
