Greetings After acquiring this beautiful transmitter it became readily apparent that documented wiring numbers were not in place like it used to be a few years ago when I helped move it. After installing the iron and capacitors I became a little confused about the blocking cap C-163. On the schematic it’s shown as a series blocking cap with respect to L-111 modulation choke. However, comparing to a photo from the WJ6W 20V-2, one side of C-163 is grounded. In the photo, C-163 appears in the lower right. You can see that all 3 of the caps are grounded on the same leg. Hence, my confusion. Compare this to the schematic and you’ll see what I mean. http://www.steampoweredradio.com/pdf/collins/manuals/collins 20v am transmitter.pdf Considering what I have, being very cautious is a good practice. These photos are not of my transmitter. Any ideas?
