[Premium-Rx] [Milsurplus] R1451A/WLR-6 - One More Time

[w3jn at verizon.net]

 Al, Sylvania made the R-1414 and R-1451 about the same time period and there are definite similarities, including the bandswitch shaft going through the boards.
Not sure how similar the RF boards are, but I do have the R-1414 manual (huge) but I could scan a few pages.

Gang,

Thank you to everyone who weighed in on this.  I must say I'm amazed at 
how many of these are in captivity.  I'll host any documents that show 
up on my site, and maybe even do some scanning if the Jersey Boys come 
through with paper.

I made some progress on my set.  See: 
http://www.ar88.net/pix/R-1451A/Troubleshooting%20A1%20-%20RF%20Head.png

So I'm really in need of, at least, the RF No. 1 board schematic. Has 
anyone been inside one of these.  I'm assuming step one is to disconnect 
the shaft coupler between the front panel and the band switch.  Then get 
the module out of the radio, pull the shaft, and extract the board.  
(There's a tool for that included.)

VY 73,
Al
