I just finished Step 2 (Audio and Video Output) of 6.
I did a minor mod when mounting the audio output transformer. It looks like they provide holes for the transformer but the chassis hole the primary wires go through would be off center and the wires would have to do a quick 90 degree turn then about 1/2 do another 90 degree turn down through the hole. That ain't happening on my watch! What I did was put the wires through the hole straight down and mark the chassis for another mounting hole. I drilled for a 8-32 screw and used some NOS 8-32 hex head screws, washers, lock washers and nuts. Much better and it looks right.
Then in one of the steps they want you to wire the speaker via 12" wires to the terminal strip. Too much left to do to finish this thing to have a speaker hanging by some wires. I did think that a disconnect pug would work great especially when I mount the thing in a cabinet. Here's my question. Does anybody know where I can get a period correct disconnect? We're talking mid 50's here.
