so no point in asking if still for sale.....
Up for sale is this vintage Bogen Challenger Model CHA-75 75 watt tube amplifier that has POWER!
It's being sold with all good strong tested tubes included:
All required tubes are now included:
2 x 5U4 Rectifiers
1 x 6AV6
1 x 6AN8A
1 x 12AX7
4 x 6AV5 GA Output tubes
The front panel has separate volume controls for each input (MIC 1, MIC 2 & Phono) and a separate bass and treble/On/Off control. The back panel has an RCA type input plug for Phono or CD connection, an electric receptacle, two speaker output sockets with a 6 screw speaker terminal strip with a wire that allows you to choose G, COM, 4, 8,16 or 65 ohms plus 25v and 70v. There's also two bias adjustments on the top to independently adjust the power tubes bias (nice feature).
This amp powers up fine and works with all of the tubes lighting up and the transformers stayed nice and cool during the testing. The sound is very loud from this amp!
The chassis and cage are in really good condition for its age with no rust at all and just very minor age related wear (please see pictures). The cage and bottom plate are present and also in good shape. It measures approximately 17" x 12" x 6 1/2" and is pretty heavy weighing about 30 lbs.
