[QUOTE="fredeb, post: 1025402, member: 13623"] With tubes in , B+ has only dropped 5V to 425V , so thats good . B++ is now slightly under 400V which is just about perfect . B+++ is waaaay too high at about 360V , so I'm going to have to change the 4k7 to 47k which should drop the voltage down to ~200V , where it's supposed to be . ATM I measure 20V across the 4k7 , so 47K or 33k should be perfect . Nice to have lights in the city . ;) Sent from my SM-G935F using Tapatalk [/QUOTE]
