AUDIO AMP CO Twin Low Power 5E8


This is the most different Tweed Amp and one of the rarest.

Different input stage, different EQ-section and a different driver. The output transformer has got a lot more iron on it compared to a Bassman, this gives a tighter low end when cranked.

The EQ is very efficient but lacks the Middle Control. This amp has got the cathodyne style phase inverter which produces more gain than the long tailed pair driver of the High Power Twin and the Bassman. Amp is an alternative to the Bassman. I recommend effective Alnico speakers for this amp!
