Hello Steveo:

Are those four each 811 tubes for the Collins 30L-1 Amp? Or did it use 2
each 572B Tubes? No I am thinking of the Yaesu FL-2100B Amp? yeah thats it.

Well look at RF Parts at http://www.rfparts.com

They have a matched quad set of 811 Tubes for a $100.oo American Dollars.

The out fit that I occasionally help out bought a new 3CX3000A7 Tube
from them for their Spectrometer. It generates a RF Arc with rock and
what not in it and analyzes the color spectrum of the rock for mining.
They won't tell me about the rock make up or anything else, but it
doesn't take a rocket scienctists to see where there all digging.

A local guy replaced the 4CX1000 tube out of his Collins 30S1 amp with a
4CX2500 tube still waiting for the results on that one.
