Hello,
I am building a system based on the following-
Douglas Self Preamp. PCB by Signal Transfer Company
8 channels of Doug self design Class G amp using PCB's by Signal transfer Company.
Linkwitz Orion speakers with active crossovers.
I have hit a snag, and am hoping someone can advise me.
Do I need to match the transistors on this design. If so, does anyone offer a transistor matching service.
Regards
Andrew

Class G amp
I have built the class G amp that Douglas Self designed and as far as my working prototype there was no need to match the transistors.My amp has been working for about 2 years with no problem.I used +- 60 volts dc for the low and +- 120 on the high side.I used toshiba 2SA1943 and 2SC5200 for the outputs.
