Hi Roger:-
Answer part by part:-
1) If the receiver was no modified, the outpot transformer for
phones es L30.- In some receivers modificated has reeplaced by one R of 100
k, and attached a tetrode tube i.eg 6v6 or 6K6 for the AF amplifier.-
2) I have many years working one R-1155 with the following tubes:
6K8 or 6J8, 6k7 in IF amplifier.- 6R7 or 6Q7 in seconddetector and 1st.
audio.- In the magic eye can be a EM34 european tube.-
3) Yes,the IF is 560 Khz. Will be adjusted warning the traps .-
4) The double triodo (V9) is CV1102, or BL63, not know reeplaced for the
american type. It is not neccesary for the amateur use.-

I hope was be useful for you.-
Excus me for my bad english

Regards
Heriberto

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
