Built out a pair of Mark 2 chassis with Poseidon boards but converted them to Ned's Tubezone version because I wanted to use NOS 5751s and 12BH7s. (Have SDS cap boards, 5AR4 and C354 installed)
On the 5751 I'm getting 165v on Pin 1, Shannon's voltage chart shows 196v and 1.44 v on Pin 3, Shannon shows 1.26v
Likewise, the 12BH7 getting 290v on Pin 1, Shannon shows 219v; Pins 3/8 have 14v, Shannon shows 10v
B+ is 517, "C" lug is 451v, "D" lug is 362v
It sounds almost too crisp... very Audio Research like, was wondering if these voltages look right to those of you who play with these things.
Am also wondering if NOS 5751s and 12BH7s might require slightly different resistor values? Ned supplies his kits with Russian tubes.
Any advise would be appreciated.
Thanks,
Ed
