What's wrong with simple kiss , boy?

I hope you're going to have general PSU for that drek ....... take two wires and one resistor from there

spoiled Greedy Boyz are wanting even LED on PCB ......

thumb of rule :

(rule of thumb is so boring )

1K for each DC volt

then , with nowadays hysteric LEDs , if too bright - ad 50%

if it's Dodo , polarize it the other way



and yes, plain 600mW MF resistor is going to be cool , with LED as load

Hi ZM
the sink visible in the photos: what is it? physical dimensions.
also the inner baseplate: physical dimensions?

local to you - Modushop

their Swiss Knife case for FW format amps - 4U/400 , with inner base for 400 deep cases

works as charm , more than decent quality , and hard to beat money/quality ratio

Wakoo 'Talians



pic (even if I think this one is for 5U/400, but you'll catch it) :

yes ...of course Modushop is my target

heatsink 5U = height 210 mm
heatsink 4U = height 165 mm

I would say that 5U is adequate for the right dissipation

4U/400 is enough for targeted dissipation , whatever you set - 70-90W per side

though , with hot summers ........ I believe nice Babysitter is making more difference than going from 4U to 5U

4U/500 would be real gem ..... but there is no 500 , without resorting to 5U

Grg, I have a problem, i set the pots as said in schematic. R6 max value , what measures about 23 Ohm across pot. R7 set at 0 Ohm.
Than i powered it up, Multimeter across R8, set for 200mV DC, and it instantly gave me the Diode-Test tone for ecceeding the measurement limit. Powered off instantly, dunno, i got to recheck everything tomorrow.
@ ZM: Potsetting schematic is right? Du you think buffer went dodo now?

srry for trouble
