Since there have been so many questions about this on the list, I guess I should try to answer some of them. It's going to have to be speculation, however, because I don't work at Eimac and don't rea

Well, this isn't the Eimac web site, just a reseller with copies of the spec sheets. I don't believe that the new tube has been put up on the Eimac site yet. The CPII site has dead links to the spec

For insulation in amplifiers, I suggest Teflon. It's soft -- not strong -- but is easy to cut, drill, and tap. It has fairly good properties as an insulator, especially looking good at VHF and higher

Well, perhaps he merely tickled the input of the YC156 through the MFJ with a tiny amount of drive. All the same, there is nothing to be gained in doing this without the filaments preheated and plate

This is a requirement that is specific to oxide coated cathodes such as the YC-156. Read your tube's data sheet for information like this. Thoriated cathodes generally heat more quickly than oxide co

When I do the math I get different numbers. At the 66% plate efficiency that is often quoted as typical for class B linear operation, which frankly isn't pie-in-the-sky considering that 50% of the dr

I have a transformer from a late 60's vintage Henry 2K-3 amplifier here, and it weighs 63.5 lbs. Although your transformer is from te 1950's, I wouldn't imagine that there is more than 10% difference
