Hiya all,

Just started work on my 1081's, and Ive started to build the power supply, but the parts list, doesn't seem to tie up with the PCB.

has anyone else had the same problem ?

Best Regards,

ok
c1= 4700uf/50v
c2=100uf/50v
c3=100uf/50v
c4=100uf/50v
c5=10uf/50v
c6=220uf/100v
c7=2.2uf/63v
c8=202uf/63v
c9=10uf/50v
c10=100n
c11=330n
c12=100n

r1=12k
r2=10k
r3=330
r4=47
r5=4k3
r6=240
r7=68

q1=317
q2=7806
q3=tl783

There was also some cuts you have to do to some traces depends if you have ver1 or ver2 of the board.
 
Cheers Fuzzbox,

Top geeza :grin:

regarding the cuts to the tracks, I think i might have issue 1 board - only because i cant see no revision 2 anywhere on the p.c.b.
what do i need to cut ?

Best Regards,

I'll email the files to you. It only affected the 48v output, apparently.

EDIT: I just sent you the PDFs with info on the PS boards and correcting them. On schems, I checked, and I don't have a schem for the PSU. I believe it was the same as Tekay's, and we used to refer to his schem. But I don't have it. Maybe someone can point us to it.
 
The TL783 can be change to a second LM317T, just add a 300R resistor in serie with the 12k resistor.
Q2 depends on what switching/ control voltage you need, if you need any at all.
