Most of these resistors are very conservatively rated. Unless a position calling for 1 watt, 3 watt, 5 watt and so on 1/4 is usually adequate, sometimes 1/8 watt. But for better sleep....My F5 boards from Peter Daniels required standing up soldier style (which I did) anything over 1/8 watt.

@Russel, thanks for the tip, will take it into account when soldering resistors.
Hey ZM, any news on psu schematics ??
Anyways, started stuffing the board and noticed small mismatch between Q5 transistors you've sent (BC546) and labels that are attached (BC556) - see photo. Let me know if it still OK to go with it.

my bad
anyway - these are non-matched - random , so use anything you have in drawer
regarding schematic of PSU , same applies as in Babelfish M25, SissySIT - general building tips and tricks , post #113

R17-18 - 5.1k got 5.6kwhich ones?
R22-23 - 1.5r got 1.6r
well, the availability might never be there anyways, i got it in lower wattage so might play around by connecting in parallel or in series to get it right if it's important to have exact valueswhy hurry?
R22, R23 - these are 1K5 , not 1R5
I should probably do this in the morning... It is 1K5 in the list I have.
Thanks for checking anyways, I should be good to go with what I have then.
ok, just noticed the size, it's not gonna work unless i buy microscope
Few questions:
1) In case using only base PCB, I should only connect AD-AS, instead of N1-N2 right?
2) Is there a good reason placing transformers in front of the case and wiring through the bottom baseplate? Looks easier to have them in the back with less wiring.

observe orientation - all LED anodes are looking at GND
Looking at schematics top row LED anodes looks other way around... could you confirm I am wrong?
