Right Channel Issue, Continued...
- Thread starter Jameson
- Start date
In essence, you have a decent amount of signal at terminals 3 and 17. This signal is stepped down through your output transformers to your speaker posts. If it isn't getting through, I would focus on the output transformer wiring.
You did the voltage checks...
You can measure the AC voltage between terminals 5 and 10 on each OT-2 if you like with the signal generator on.
It is incredibly unlikely that there is an issue with the output transformer (you would be the first person ever to have a defective OT-2).

You could definitely take advantage of the repair service. You might also want to post photos of the OT wiring on each side.

Jameson,
I use an Exacto blade, I lay the blade on the insulation with light pressure and roll the wire under the blade. This will cut almost through the insulation, then use your finger nail to strip off the cut end of insulation. A little practice to get the pressure right and you can strip that CAT 5 wire without any nicks.

Paul - Here is the wiring for the right side output terminal.
The current status after a little prodding around over the weekend is:
You'd mentioned previously about installing jumpers to troubleshoot. Would that be my next course of action?
The current status after a little prodding around over the weekend is:
- Right channel is completely out
- Left channel is working but staticky
- Voltages and resistances are all within regular parameters

If you don't have one perfectly operating channel, then the jumper tests won't provide any conclusive results.
Ok. Hopefully I’ll get some time in the next couple weeks to devote to getting the left channel back. The only thing that’s changed there is the pot, so it should be easy enough to isolate. I picked up an extra foot of Cat 5 just in case.
I’m kind of baffled that everything was working reasonably well for a month and then just imploded. Doesn’t inspire a ton of confidence that I can pull off the builds for the Stereomour, Smash, and Reductor that I have boxed up and waiting to start.

Sometimes just purchasing some tools that are slightly better suited for the job will make the build process a ton easier.

These showed up last night. I tried them on a couple spare pieces of 24 gauge wire I had laying around… Wow! Really nice stripping. Thanks for the recommendation!
Our fiscal year ends tonight (thank god), so I shoul hopefully get some bench time on the amp this weekend.
