Iím redoing this SX-62. I got this up and running but the no name
Output transformer lasted about an hour. Audio was ok but very low even at full.

Previous owner apparently ďrepairedĒ this with random parts and then left it in a Michigan shed since 1963.

Currently replacing output transformer with a correct output transformer 55B077.
Iím measuring about 400 ohms on the primary - with 200 ohms between the center tap and the other taps.

My problem is that the wire colors have faded. By the schematic the red wire is the center tap going to L1.  I think that I have correctly identified the red wire with use of a loupe and a bright light. I assume the middle wire which appears red is the center tap per the schematic but I make no assumptions about how Hallicrafters does things.

My other issue is v12 the 6v6 socket is broken. Wires were removed but no new socket installed. I have a nice octal ceramic socket which fits right in but now Iíll have to trace out the wiring to see what goes where.
