NEW SECA PCB
Power can be set from 14W - 40W depending on heatsink.
The PCB's are £60 each. Please contact Mr Brown on http://https//www.abcaudio.biz/
The PCB is now leaded components and should be easy to assemble.

A question for Colin.

I've got a pair of V1.0 PCBs that came from you quite a while ago.

Do they differ in any significant way to the boards currently on offer ? V3 I believe.

All leaded components no SMD (well 2 it you want to use them) simply to build. Better BW a smidgen, mount into mod shop case.
But best of all one can be a master and you can have 10 slaves with a bigger heatsink and huge transformer you can make a 300W mono, OK OK 1800W of heat but no logs or coal to bring in from the snow in winter I think that's a added bonus. Oh that just one channel, for you cold morsels. Total 3.6KW stereo and just 7.2KW for quadraphonic ideal for digital lies Dave, honest.

Colin
Can you use your dynamic PSU instead of the one on the schematic ?
Thanks

Not sure on what you are asking, if it can you add a PSU Dynamic to this yes you can but on testing on the right heatsink there was no need. Except you could push it to 50W.
