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.

If you have rust between the vanes, I wonder how you get the NJ in between, and how you then wipe it off.morzh — 12:02 PM

If the noise is still there, the OPT might just be OK. Or so we hope.morzh — 12:01 PM

You would probably be replacing the OPT.RodB — 10:54 AM

Thanks guys. I think I'll give the Naval Jelly a try since I can better control where it goes.dconant — 09:23 AM

Just forget this number, it is useless anyway. Simply proceed with your project.morzh — 10:08 PM

My $0.02 is that it is a misprint. I tried to look up the value for the similar 84 and 37-84, and ther is no resistance...MrFixr55 — 09:51 PM
