Power supply was also my first thought, but Nixies light up and if I

I have already emailed k5cm asking if he has the manual
The have a few manuals online:

but not the GR1192B. *Send them email as I'm sure they have a printed
copy in the archives that only needs to be scanned. *Maybe just the
schematic and block diagram.
I did get to ietlabs site in my first searches. Never thought of

Cool. *One question. *Is the frequency range of the Eico the same as
the Heathkit ranges that I listed? *I'm curious.
Eico 710 has 8 coils starting below AM BC band:
L1 0.4 - 0.7
L2 0.7-1.38
L3 1.38-2.9
L3 2.9-7.5
L4 7.5-18
L5 18-42
L6 42-100
L7 100-250
