Carriba!.
Thanks Mike. If i do go that route might source some proper ones from Dada -possibly why i have some spare new ones. I think that is what i did before on another 303 i built with new boards from China some years back - similar to that old thread - possibly ten years now. No access to a scope unfortunately only multimeter.
I should have mentioned - brain fog - once switched on for the first time in the day it doesn't pop on subsequent turn on during the day unless left off for some time - would that point to capacitor charging up for the first time and then depleting if left off for a period of time?
I did post this on the FB Quad group and suggestion is to go over all the joints on the board and re-solder so a job for the weekend.
