Maybe post some pics, including one of the entire underside.

Interference in left channel
- Thread starter Nignoog
- Start date
I am wondering how helpful pics will be for two reasons:
1. I sent my Crack in to be repaired a few years ago and I haven't touched it since.
2. If the interference goes away when I relocate the amp, shouldn't that imply that the issue lies outside of the amp, not within?
I am happy to post some pictures if you and others think it might help, I am just weary about the prospect of having to do an soldering.

Dunno. But what's the harm in posting some pics?
I'm curious as to why the interference only shows up in the left channel. That suggests to me that there is something about the wiring of that channel that makes it more susceptible to picking up noise. Maybe that's something worth exploring. Pics might help with that.

Yes, this is quite true. It's somewhat possible that picking up a cheap pair of used tubes on eBay might mitigate this issue a little bit. It's certainly an inexpensive experiment to try!Nignoog said:
I have a few other tubes here already that I will try.
In the meantime, I am wondering if the picture I am attaching shows what is negatively impact the Crack's performance. I noticed that the building across from mine has a lot of satellite dishes and antennas on the building. And the area in my apartment where there is no interference is in the opposite direction. If you think the antennas are the culprit, is there anything I can do short of relocating the amp?

Yeah, that would do it! It's probably particularly bad because you are up above the ground and those are aiming right at you.
One thing you could try is to buy a 0.1uF Z5U capacitor (voltage doesn't matter) and solder one end to the right RCA jack shell and the other end to terminal 22 (be sure terminal 22 has continuity to the chassis plate). That may give the noise an alternate path to travel that isn't through the circuit itself.
