Can anybody of anything to talk about this weird Amplifier?
I got some specimen. It is some kind of 100V line amplifier, but there is no information even on the internet.
And I also ask here - maybe someone knows something?
Amplifier has made an interesting - its input stage is used integral amplifier TDA2030, the power stage operating only N-Channel L-FETs, namely Hitachi 2SK135
, they are 6pcs in each amplifier, is it a MONO-amplifier.
The back panel is marked with the manufacturer: Communication & Control ENG CO. Park Road Calverton Nottingham – England.
Model: Power Amplifier TYPE 770/200M/A/382.
I check the MOSFETs and they are all good-). It is also the output transformer, maybe they can use without rework in a tube amplifier?
Or can anyone here to talk about this amplifier?
I do not have a schematic - so please don`t ask it
