@Liliya
I have 4 symef boards coming this way and still haven't started the 1diffqc build yet. Maybe you can have a couple of boards from me if I only need 1 pair.. ? It depends on my relatives that also want a great poweramp.

Harrison, I will wait for your next project that you told us in your last post in the SYMEF thread.
I stll have not finish my 1DIFFQC project, due to a stupid failure I did. A couple of TIP 142 went to "heaven". Repairing was set on hold because of a "house project" (painting) before Christmas.
For the time I am finishing my variotrafo project. As soon as I am throuh with this, I will give 1DIFFQC a new try. I hope to come back with a short listening test to 1DIFFQC compared to SYMEF.

Eivind Stillingen
Looking forward Liliya,

Thanks again, Harrison.

Sorry for the fuss......I am running Fiefox19.0.2 - a beta test browser - and have now had similar problems with their new .pdf viewer. Save a .pdf and it gives a message saying "damaged file". [I'd just managed to get them to print when the ink ran out ... totally forgot to reorder - so it will be a few days before I receive some. Our local town is a one horse town and that died last year!.....beautiful countryside though.]

thank you for the explanation.
IMHO, this is not a practical way.

Received my two boards today.
Still not really convinced about the location of the transistors and how to mount them onto a heatsink.

Regards
