[Collins] HP 410 b

[appo2 at juno.com]

2-01c or whatever it is,,I have a few of it somewhere,,,NOS .
EA53 or whatever similar is used in 410c,,which is my Collins utility
unit.
I had both in many ham radio swap meets,,nobody ever offered me any money
in past 20years.Instead,,I have a tie pin made out of 2-01C.I forgot who
gave
it to me at ham radio convention or swapmeet.
I collected too many 410c's,,want to get rid of them all,,,these are
excellent to
measure power output to balanced mixer adjustment in M2 and Sline.
Solid State unit will not do it.Needs extra attenuators to bring them to
proper
measurement range.
