Greetings to the group!

I'm new to the group and new to running more than barefoot power. I will now be 
running power amps with my Collins S-line, KWM-2A and Icom Pro radios.

I'm wanting to check some 811A tubes in my Hickok 800A tube checker and the 
811A or 572B is not listed in the manual or on the "wheel" chart. Can this tube 
be checked and if so does anybody know what the settings would be? I would also 
like to know of a good reliable source to have on hand for a tube cross 
reference chart.

I'm also in need of some 6146, 6146B and 4CX-1000 tubes, any good sources the 
group knows of would be appreciated or anyone that may have some good-excellent 
used tubes available for sale please contact me off list.

I will soon be posting to my web site some detailed pictures of a home-brew 1kw 
amp that an engineer of some 28 years at the University of Iowa built back in 
the early 60's and ran with his Collins S-Line. I got the power supplies and PA 
all mounted in an original Collins rack from him. He use to shop the Collins 
Outlet store in Cedar Rapids. His health is not good and a recent stroke left 
him virtually blind, although he is available to talk to. He is a true 
"gentleman" and I would like to resurrect his station, I already have his 
Collins S-Line station working and it all fired right up and just worked, which 
says allot for his equipment and Collins. I promised him I would make a contact 
with him at a friends home in Ames, Iowa using his original station when I got 
it all going. The schematics he found and included are home-drawn and are 
fairly complete. The design and appearance of this amp looks excellent, as well 
as very professionally done with top components.  It's not a hack job! It was 
working for his last contact in his log book in 1984 and has been kept in his 
basement clean and dry.  

I will be looking for someone in Texas or near Austin to help me fire this amp 
up, for which I'm willing to pay. If someone is or knows of someone who is 
experienced in working on this type of amp please contact me. I'm in Quincy, IL 
in route back to Austin with the equipment in my van and I could stop along the 
way. Extensive pictures have been taken and I'm working on posting them to my 
web page very soon. I will provide the URL to anyone who would like to view 
them.

This is my first post and I will keep future posts a bit more abbreviated.  

Thanks in advance for any help the group can provide,
