Hi!
Can anyone point me in the direction of circuit/diagrams and PCB layouts for an experimental Class D amplifier board using through-hole parts only and output inductors wound only on readily available Ferrite core kits please?
I'm looking at outputs in the 20-50W range!!!
Many thanks,
Chris Williams

Try the TDA8920BJ it comes in both a through hole (23-SIL) or a surface mount package. Digikey has them in stock now in the through hole for $6. It is made by NXP Semiconductors (founded by Philips). Philips is the same company who Bruno Putzeys worked for, though I’m sure it’s not a UCD topology.
The Dared DV-6C uses the TDA8920 and in was awarded 6moons Blue Moon Award in 2009, so sound quality should be excellent. I trust 6moons far more than other reviews. I don’t know if there is a difference between the through hole (23-SIL) or a surface mount package the data sheet does not sagest it. I have not heard it myself.

I was wondering about something like tda8920jb, i have had BTH but i killed it, heatsink+ground ...
Now i found this:http://www.elsemik.ec24h.pl/avt14921-b-wzmacniacz-2x100w-tda8920/
I did everything to get it, i as every ready to rob bank, until i asked them about shipping...
Im depressed i need 3 of these boards right now, my class D surround system will never get done, has anyone tested these?
I didnt know much about poland but theres many many things i cant even buy from ebay
