Just finished all boards.
Fire up, nothing smoked, all are good.
Measuring Vout at shunty +/-20v
VR not working, nothing happen turn left or right
Vout still the same no changes.
IRF using 610 and 9610
All other component according to BOM
Can someone explain why?
Thanks.

send me pictures at mail , to leave too much traffic of forum
did you made everything by the CookBook , including use of resistor load for setting ?
with pictures send me also data for xformer
it must be some methodical mistake , judging that you have low and same voltage on both rails

Hi zm
Sending all pics.
Yes all according to cookbook.
R load are 500R 5watt.
Tried to replace 4R7 from AC inputs (into jumper)
Still the same no changes with VR turn left or right.

Just finished... (sorth off) my Pumpkin today.
Tomorow rest and enjoy 😀

I finally started sorting parts for my Pumpkin and Shunty.
Is the 100uF capacitance for C10 and C10A (Shunty schematic in Pumpkin Cook Book) critical or can I use the 82uF/25V that I have in my drawer?

are those different LEDs ?
I really had intention to keep cascodes at 6x 1V93
ok voltages aren't so critical , but green ones are good in noise department

I only had 6 green 3mm leds left. The yellow measured the same voltage (1.94V) using a component tester so I assumed they would be ok.
Leave the yellow in or replace by 5mm green leds?
