Up for sale is a Bogen Challenger Model CHA-75
75 Watt mono block.
Apparently a PA amp from the early mid 70s
(This model is from 1974)

It's being sold as is, without all tubes

Required tubes are:

2 x 5U4 Rectifiers
1 x 6AV6
1 x 6AN8A
1 x 12AX7
4 x 6AV5 GA Output tubes

+ New power cord has been replaced
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
The cage and bottom plate are present and also in good shape.
Includes original metal cage

It measures approximately 17" x 12" x 6 1/2"
Weighing about 30 lbs.

Powers on!
All very strong tested tubes (all heat up and glow perfectly)
Its in pretty good shape.
The previous Cam member owner of this amp gave it a 7 and I concur with him and also rate it a 7 of 10
(due to a few scratches on the upper case and a broken knob.)

Payment by: CASH,EMT, Canada Post Money orders
(No Pay pal please,as we are not users).
Local GTA cash pickup preferred

I am reluctantly selling off much of my vintage audio collection,
so that my youngest son can better afford to live in residence with his harem scarem at his university on campus...


It's being sold with some of the tubes included
