Unmatched EL34 in a 205.

Post by namklak » Sat Jul 08, 2017 7:09 pm

Hey,
Valve Queen has unmatched SED Winged-C. It seems to me I could buy two unmatched for my 205, as I can bias them separately. Will this work?
Thanks,

JVM205h. Added 100K from R94/C43 to ground for V1b (OD Channel) gain reduction. Installed 1000pF in series with 47K, in parallel with R58 (82K), to reduce power amp squeal. V3 Valve Wizard diode protection mod. Active power soak for more EL34 goodness.
Guitars: Angus Young Sig SG w/ Pearly Gates Neck and Custom Custom Bridge, Les Paul Special (2 pups) w/ SD Stacked P90s. And occasionally a Warmoth Strat w/ Dimarzio True Velvet in N, M, SD P-Rails in B.
HD500x in 4CM for all pedals and Midi control of 205h (grounds lifted on two of the signal cables).
