Just completed a a zwreck build, having current draw issues. I used a two el84 output stage, gz34 rectifier. Power tranny is a from a hammond ao43 this is the fourth wreck style build I have completed using this setup all the others work flawlessly. Power supply is as follows
from rectifier to stby, stby to 250ohm resistor and 40mfd cap and bplus 1
output side of resistor supplying bplus 2 then dropping string paralleled to b plus 3,4,5. of bplus 2 node
I have low bplus 1 only 100v. The amp sounds wicked good, less this little current draw issue, any thoughts

Re: z wreck build power supply issue
Funky PT or rectifier perhaps?
What are you seeing for voltages on the PT primary and at all the used pins of the GZ34?
