Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

yes I have a multimeter

Yeah I have a multimeter,

Both the 12AX7's and 6SN7 have 6.3vac, The 6550's have 7.3vac before the R68 resisters.

With the 12ax7's and 6SN7 using center tap after the choke in the HV rail, the heaters for the 6550 have the low side grounded in the schematic. What would cause either 6550's to power? This is why I tried with no ground.

Very good questions guys, thanks. I am having troube uploading the schematic. I have apple computers so I will try with my other one later.
