[AMRadio] Testing tubes

[DOXEMF at aol.com]

Jim,
Here's a Site in Korean that has some graphs and 
info but the Eico 1030 P.S. shown is the perfect
supply source for good regulated H.V as well as bias and filament.
I have found several cheap at Fests and they seem to be 
a hidden gem for tube audio work.
There are two 6L6's as pass tubes with the ratings of 400v at 150ma
which is conservative.
I put 6550's in mine, changed out the meters to read 500v and
250ma fs, upped some cap v ratings and can now get 475v at 200ma
no problem.
I added several digital panel meters for precise V/A readings
of all tube elements and it all cost less than $100.
Perfect for most power tube specking as well as working on any type of tube 
gear.
I will post the whole configuration when it's all reassembled.
After all, where would our AM be without good AF power tubes.
 Enjoy,
Bill KB3DKS
