Sibelius a new amp
Top left PCB convert Balance to un-Balance,Top right PCB is the twin bridge PSU with 88,000uF Caps and the 12V supply for the Balance PCB and the ON LED drive. The bottom two PCB's are the power Amp, they will be running 35W P-P Class A.
NOTE:- The balance PCB can have a variable gain control not used in this project.
Running the PCB on +20 and _20VDC will allow with larger heat sink a deeper current and more Class A, also note the DC offset can be adjusted to less than 1mV, max current is 12A continuous and 1mS peak current can be over 100Amps. Then the fuse blows.
Great fun on a lock down day.

Hi Colin,
Most of that except the 35w bit went right over my head, but that looks really interesting, eventual cost of completed amp?
Hope you are both well, I see you’re keeping busy

Well another personal money pit, they do not seem to want to pay for R&D, and seem like the same thing that as happened in the past, a freeby design. No way this time.
