My 38-690 Project
#5

Pictures of the restored chassis's with new caps and candohms. I like the look of everything freshly painted.

While I was in the amp chassis I found that the tweeter wiring needed to be corrected so that the speakers were in phase. I followed the post that Ron made to correct this issue. In addition, I found the audio Transformer wires reversed, or at least the colors did not match the schematic. Once corrected I had much more volume. To top it off, I replaced the coupling cap with a 4.7uF film cap which really gave the tweeters presence.

I threw in the sub chassis photo, as I had it out to replace caps, resistors, and clean the switches.
