Thanks Heriburto - bookmarked, and some pages printed for bench use.

-- I can't find the phones o/p transformer (designated L30) anywhere
in the chassis - not even the mounting holes!

Ah, ha..! I've found L30 from a VMARS sketch. I was looking for
something much larger, like a radio OPT. L30 is tiny and buried under
wires, etc!

One last question (Q3): Is the IF 460 KHz or 560 KHz? I've seen
reference to both numbers.

Ans: It's 560 KHz, from the VMARS website

Do you, or does anyone else, have the equivalent commercial tube
(valve) type for the VR-types?
Here's what I have to date (hope the columns hold together):

Rec number VR-type Commercial
__________________________________________________ _
V1, V2, V4 VR99 6J8G (triode-heptode)
V3, V5, V6 VR100 KTW61 (NA type?) (RF pentode)
V7, V8 VR101 6R7, aka DH63 (dble-diode triode)
V10 (eye) VR?? ??
V9 VR?? ?? (double triode)

Thanks and cheers,
Roger
