Missed the post on dual-mono Russell. What I have for trannies is the Handwound replacements they build for the Dyna ST-70. The specs are similar but the build is better. They can run EL-34's or KT-88's 6550's etc. The plitron Iron is they way to go. What I was thinking was to build with the handwound then substitute when funds permit. The circuit seems adaptable to either or. J.R.

J.R.

I got my copy of VTV 19 (and 18 and 17) and had a chance to review the KT88 design. One question for you. What are you suppose to bias the tubes at with the bias setting?

Hi Garman; I am not sure what you mean. I believe it is set at -62v. Is that what you get? J.R.

I was just confused as to what the bias metre should read with the adjustment of the two 10K bias pots. Gar.

I wonder if it would be possible to model it with Circuitmaker?

I sort of had the same idea. plitron is the bees knees, but thats a lot of expensive iron if one goes it all at once. Russellc
