Yep.
I'm starting to think the trimpot may have went poof, because the 1000uF cap leads were/are shorted or the cap is shorted internally.
Would having the jfets switched caused the cap to internally short? I looked at the leads protruding from the underside of the board and I dont know how an external short could of happened.
So I have learned.Maybe just a poorly manufactured trimpot.
The lesson here is always buy spare parts.
Since I have got a place an order now should I remove the 9.1 zeners in favor of the LM329?
A lower voltage zener or lm329 is a good idea.
Anything between 6V and 7V is good.
Use Bourns trimpots. There are so few parts so make sure you buy good quality parts.
Parts ordered. I guess I am in a holding pattern till they show up.
Worth checking the capacitor is ok.
Take it out and test.
Or just replace.
Try not to put too much heat into components when soldering. That is get the soldering iron in and out within 3 seconds.
Allow heat to dissipate before soldering next lead on component.

Is there an optimal temp setting to have a soldering iron set at? I've got a Weller WES51.Worth checking the capacitor is ok.

not much difference
Thank you! I have both values. Seeing as the schematic says 3.3k ohms that is what I will go with.
