[AMPS] 4-400 replacement

[John T. M. Lyles]

I got home from the NAB convention in Vegas last night. Reading the 
questions and answers here, I saw someone looking for big coils. 
Besides Multronics, Phasetek had some nice looking pieces, and 
complete antenna tuners and phasor systems for broadcast. Kurt Gorman 
is the pres, in Quakertown, PA. (215) 536 6648.

Kintronics in Bristol, TN also makes big coils, and should have a website.

Penta Laboratories is still in business. They showed a '4CX400' 
ceramic tetrode which is made to fit into a glass 4-400A or C socket. 
Claim is that it is a drop in. It looked a bit rough, esp the fins on 
the anode. I saw a data sheet. They claim to be working on a 3-500Z 
replacement in similar fashion.
