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?

Also, I have 12uF. Can I use these instead of 10uF for C9 and C9A (Shunty)?

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?
