Well they've seeming fallen into Adminstration - Their Premises are in Mansfield UK.
All I can say is the design is going to be as simple as a fuseholder. They always are.
I'll scrabble about my designer mates - I used to do contract work for this company and still have some sources - cant promise anything
Hi Andy,
Did you get any further with this? I'm trying one of these amps in my system and would like to see the circuit to work out how to increase the bias current, as the amp sounds a bit grey and hard.
So far all I've done is remove the nasty pro-style connectors and replace them with good binding posts and RCAs, and replace the fan for a Panasonic Panaflo @ 6.9V, and short out the input caps and replace them with 22uF old Wima film caps. It sounds good but I'd like to increase that bias and I see no trimpots so I expect it's set by a resistor, but which one?!
Regards
Simon
