Hello Dick,

Well, I'm beginning to think that I have things backwards. It's a bit like
building a boat to fit the size anchor that someone has given you (;->)...

I haven't read the article thoroughly, but no less an historic personage
than William Orr, W6SAI, says that the 4-65 is not suitable for grounded
grid. Here is the link:

The 4-400 sounds very likely, and I read somewhere that they are a bargain
due to their common use by commercial stations. Any suggestions for where to
find them?

Cheers,

Brian  

P.S. I was W5BRO down in McAllen in the early 1950's
