Mike, I just got the manual in my E-mail! Thank you
Really interesting stuff, I noticed the manual says it has a 12" tube, but mine is 10" Looking closely at the mask (see pic) it looks like there is a section around the edge that can be removed for a bigger tube?!?
Also it shows me that the knobs I have are correct, I'm guessing they had a lot of channel 1 escutcheons that were useless in 1949 and decided to use them for knob trim
Waiting on the Electrolytics to arrive from mouser so I can get started on this thing!
