Hello-      A long shot here. I am looking for info on a 3CX1000A7 VHF 
amplifier by Bob Sutherland (and two other authors in second article) that 
appeared as a 2 part article in March 1969 HR Mag page 6 and April 1970 page 
26. What started my inquiry was discovery of a plate line assembly from the 
estate of a well known Collins engineer JB Jenkins W5EU. I recognized the 
assembly as from this 2 part article of which I have studied in past. Mostly 
for the sake of historical reasons, and learning, I am asking these things:     
   1. Does anyone have a copy of the full set of plans that are offered by 
contacting Bob Sutherland at Eimac as referenced in March 1969 article? I 
surely would like to have a set to go with this plate line assembly.
        2. Does anyone know if any of the complete amplifiers as offered by Al 
Roach W6JUK of Dymond Electronics were ever produced? This is referenced in the 
April 1970 article adjacent to the picture of the modified Henry 2K amplifier 
(modified by Bob Sutherland at Eimac to incorporated 3CX1000A7 RF deck using 
Henry power supply).
    I am curious about the history of this 2 part article and if there are any 
pieces of equipment that survived from it. I don't believe I would care to 
duplicate the complex output coupling scheme and mechanics but it is 
interesting to study. I would like to try and find a copy of the construction 
plans to go with this plate line assembly.
Thanks,Byron W5FH936-349-6353 cell
