Hello Peter,

I received them last week, they are looking beautyful.
I am scoring the parts here and there and will post the end result.

best regards John

Hello Peter,

I have received the boards yesterday and as already said, they look beautiful.

Thank You

Can anyone suggest a good source for parts (transistors that is). I could not find anything @ digikey or mouser.

Thanks

You should be finding most everything there. That said, I took the easier route of using Tech-Diy parts pack. Jack participates on this board.

Note that the Tech-DIY parts kit needs a bit of work to mount properly on Peter's board. The resistors are all mounted vertically and the Ohmites mount to the back of the board. Can take a while to figure out how to mount these on a chassis this way...

I just used the standard Tech DIY parts and stood the resistors up soldier style.

My parts kit was a bit different - I got sent a bunch of Ohmite resistors (which NP mistook in someone else's post as a cap).

This is my board:

The board was designed to be used with Dale CMF50 resistors, available from DigiKey: http://dkc3.digikey.com/PDF/C091/P1890.pdf

For the large ones, use 3W Panasonic metal film, also avaialble from DigiKey: http://dkc3.digikey.com/PDF/B092/P1920.pdf

You may also consider 5W Mills and then use single 50R resistors replacing R5/R7 and R6/R8 parallel combos.

I would also suggest simplified amp circuit, without protection circuitry and thermsitors; it really works nice and according to others sounds better. Since such version uses even less parts, you may also consider Caddocks or Vishays: http://www.audiostereo.pl/zalaczniki/1272620_1.jpg
