Forget the link to the datasheet: http://www.g8wrb.org/data/Eimac/YC156.pdf The only thing I have against the YC-156 is the noise...damn, they're loud, if you're wanting to run power and keep 'em

Re: 3 x YC-156's vs 8281
Last 8281 I bought brand new set me back about $1050, and I think I had to add a socket. And, the tube's pushing good and hard at 20k, while a trio of YC-156's is loafing at 30K. Remember, a YC-156 is
