Use BD139-140 instead any higher speed transistor so no need any compensation caps.

Congrats. You are the first to build the dual FET PeeCeeBee made of edible sweet solids.

Please upload the pdfs of layout, silkscreen and mask if you think we should eat... uuh.. build it too.

Again, what innovative speakers John, quite inventional haha...

The speakers just for fun has build it long time ago

So here the PDF but no value cos I don't have it

please send me PM if someone want the .dip file(I use diptrace)

board size : 100mm x 64mm

Hi wenz.

I think it is possible.

With CFP/Sziklai outputs the amp should produce good sound [with some extra care to prevent oscillation in the o/p stage].

All the best.

I already have a DIY amps, all are TEF, I did not try CFP/Sziklai outputs,
maybe I will have to try CFP/Sziklai and modify it to TEF if CFP is working.

Default last version

Here the latest version, some tweaks and fixes. The spaces are great for those who want to use polypropylene capacitors, but can also be used small electrolytic capacitors.

Sorry if it's posted in the wrong location, please enter the correct location

Thanks.
