Triaxis problem: unit turns off and makes loud noise

[Harsh]

Hi all Triaxis users. I bought a used version 2, non phat Triaxis a couple of weeks ago and already have problems!

First, it started turning itself off and on quickly. Now, it has progressed to the the unit turning itself off, while the tubes continue to glow. It also makes a loud unpleasant noise. After speaking to Mesa tech support and Fatboy, here's what I found:

1. Check the ribbon cables in the unit. Older Triaxises have known issues with the ribbon cable connections going corroded over time. Remove the ribbon cables carefully and clean the connections.
2. The voltage regulator in the Triaxis (LM323) does not regulate 5 volts correctly. This causes the unit to overheat and reset itself. Replace this part.

Guys, please correct me if I'm wrong, or if you have had similar issues and want to add some info, please post. Any help would be appreciated.

Cheers.

Check the ribbon cables in the unit

A big +1 (or even +2, +3, etc...) on that one.
I had to replace all of mine. The original ribbons just were not that durable. These older ones have the multi colored wires...the newer ones are grey with a blue stripe on one side.

I have also heard of the voltage regulator issue.....mine is a newer unit, though, and never had this problem.

Good luck
