to Anthony A (#166):


the 2 pics on the left give me a cold shower on my back....:eek:..:D!


to zen Mod:


very nice work on your pcbs! Are you going to offer / sell them to
the plebs?
At the moment I try it point to point. But looks more professional and
shorter paths.
Greets
Dirk

as I'm always saying - it'll be either All The Glory , or Major Flop in Public :rofl:

in case of first one , I'll have them available for Greedy Boyz ....

proper testing , and I hope to be satisfied with outcome
 
to Zen Mod:


I am sure you will get all the glory! I'll get the horns and trumpets ready to
salute you as the winner of the olympic games in the Olympic discipline of
fast pcb-designing.


myself:


I think I have to change my forum-name to 'master of disaster' or

'copper - bender`? See attached pic.....:bigeyes:

lousy late night pics

lazy to arrange proper light

missing some tiny parts - few caps and small Graetzs, need to order them tomorrow ....

so , testing in few days ......

In the "SIT multi-flavor" lower PCB schematic what is the voltage at the gate of the IRF510? I don't know what the forward voltage is on YOUR green LEDs.

What is the A/C voltage at AC1 and AC2?. I am guessing 22VAC to run the buffer at 28V regulated but, if you write down the voltage, we don't have to guess, eh?

it's sorta too early for tiny details , prior to even firing them up
however , I'm counting on plain old difuse 3mm Green Leds , all of them having 1V93 at few mA

so , logic is to have tiny smd JFet buggers working at something as 9-10V

for SIT gain pcb , AC is once 15V ; if you calc , output voltage of LM317 reg is soso 12Vdc , so 15Vac is resulting in nice headroom even when mains goes funny (-10%)

rarely seen in my neck of wood , but that's my habit - taking that in account

for Mosfet gain pcb (xformer Schade etc.) , auxiliary xformer is , say, 30Vct (or 2x15Vac )

in both cases 100mA sec is Plethora of Pinjatas
