I use this one, fed from the 12v lv to delay hv output. https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.nl%2Fulk%2Fitm%2F122078937183
I use a drop resistor to feed the cpc1117n
Two Methods for adjusting ccs. Got the link from here somewhere I think.

I use The v tap guide From big gator tools with success. Use their drill hole guide for the drilling. I have no drill press. https://biggatortools.com/v-tapguide-faqs
I thought I did that already but seems not the case. I deliberately avoided vague eBay sellers and went for a seemingly reputable seller (not through eBay) in Germany. And maybe the tubes *are* okay and something else is wrong with my build. That is why I seek for alternative measurements on the tube side as well as on the amp board side. Will ponder about buying extra tubes though. Any suggestions for sellers in Europe? Verzonden vanaf mijn iPhone met Tapatalk
Pity, local tube seller is not that helpful. Pondering about another DIY project to help myself out: http://www.dos4ever.com/uTracer3/uTracer3_pag0.html Is it up to the task?
Is it helpful to power up the amp without tubes to measure voltages at the pins to verify that all tubes (output vs CSS of course) get the same input?
