Wanted Lafayette Comstat 25B Late Version Manual/Schematic/ Block Diagram/ Alignment

[SuperLid]

Wanted Lafayette Comstat 25B Late Version Manual/Schematic/ Block Diagram/ Voltage chart/Alignment.

There are two versions, early,uses 6AQ5 AF amp, 6AN8 RX OSC. The Late version uses, 6BQ5 AF amp and 6BL8 RX OSC.

The SAMS I have, covers the early version radio, which, is not providing the info needed and has many errors.

I am going to use the Teaberry Model T SM for now.

Thanks,

SL

what about the robyn t123b? That schematic looks identical very similar, but with the tubes you mentioned.
