The possible marks in resistors (3W) are in the listing of the manual of Fab, all fingerprints except the condensers are not made to accommodate larger sizes because it is useless and especially to keep reduced dimensions of the printed circuit.
Here are some examples:

Where can I find more information?
I see one PC board has feedback caps the other not, what is the reason
Thank you

Do your reading.
You can learn much and there's nice pics.
Thanks orginal theme for all fun.

The third picture is an USSA-3 with jfet input thus no feedback caps needed.Where can I find more information?

Hi Tonza75
Thanks.
I have added a coma because it was changing the meaning...
The USSA-6 proto is an class AB amp (high bias for class AB though).

Hi
Please send me a PM with your home address (to calculate the cost) and then payment to my PayPal account. Read post 1 instructions. However, I have already ordered the pcbs for you from the preceding group buy #5 so I can begin to ship to the peoples providing home address and payment.

The holes for capacitor C2 are spaced 5mm, 27mm, 34mm and 41mm apart.I've seen something like a short list which resistors could be matched closer to get a better performance but I couldn't find it anymore. Can anybody tell me where to find it?
It would be also nice to know what are the possible lead-spacings for C2. Anybody can tell me? Thank you
The drawing indicates a 36mm length and 19mm width capacitor in available space without touching the other components but it is quite possible to put a capacitor a little bigger.
For the resitances the best is to choose the ones mentioned in the list of the manual of Fab.

There is no special matching of individual resistors needed. 1% telorance is sufficient and widely available.
Unless you mean adjustment of equivalent resistor value between positive and negative sides for the similar Mosfet drivers current...if that is so then refer to sections 8.17 and 8.18 of the manual.
