Yes, to measure AC volts you want to use the AC volts setting on the meter.

Chalk up another for Doc, PB.

Wow I feel dumb. I just saw in the instructions above the voltages in the instructions it said dc closest to 400... my bad.

And apparently you are VERY good because my 6080 just turned on for the first time, despite not changing anything from last night. The following are with both tubes in (AC500)

More or less yes. I haven't systematically gone through them 1 by 1 but I've resoldered almost all at least once, many several times. I'll keep at it though.

Alright so went through them 1 by 1, only thing I really found was B6->T1 looked a little sketchy. Redid that and several others... and bam. New voltages all approx 10-16% from the guide, everything lights up. Thanks so much DocB and PB, one of the reasons I trusted myself to make this in the first place was because I heard about bottlehead's amazing forums/support if anything went wrong. Now on to listening!

Yes the keyword is all the solder joints. I don't understand why so many builders are so stubborn about reheating every joint. It takes like ten minutes. I couldn't count the number of customer amps I "repaired" over the years that I simply reheated all the joints on.

I think this thread is the best example I've seen yet of how outstanding the BH customer service is, how timely responses are provided, and how well troubleshooting from afar can work.

Congrats to chavac for not giving up and for successfully completing your build!

Best regards,
Adam
