Re: New poll for ham_amplifiers
Funny, the YC-156 TRIODE has 3 times that gain in GG. I drive my grid driven 4CX3000A by a 4CX350a in class A which I integrated into the amp 73 Peter wrote: motivated by a pair of UTC CG310s on

Re: New poll for ham_amplifiers
Yup Mike, They all went to Frank because I have a box of 4CX3000As. They also work well in GG mode and have a bit more gain than the 4-1000A. wa1gfz Mike Sawyer <w3slk@...> wrote:
