okkkk... so it's a normal diode, not a zener... I could have tried for months
now I put a z12v

now I put a z12v
okkkk... so it's a normal diode, not a zener... I could have tried for months
now I put a z12v
I'm waiting for the measurementsput 15v
Wait
D2 voltage, D1 voltage
relative to GND
D2 = 17,15v / D2 + D1 =25v
the common DMM probe is on the body...
Put D2 15v
(+ D1 15v ?)
Yes
put D2 original stock in place and put D1=18v
and check if something has broken next to the jFET.
it looks like the oscillator doesn't want to oscillate, maybe îs the disk
D2 îs the original stock ?
Yes I put it back
17,27v at D2
Let's go to plan D
In series with stock D1 and D2, we put a 4.7v zener, in the air. With the disk.
respecting the polarity.
Plan ED2 17,20v / D1+z4,7v 28,22 / polar +57,43v
looks like we're standing still...
how many plans have we got... ?
replace the 4.7v zener with a 6.2v one
