    Triaxis Optocouplers, LDRs, Relays

    Thanks. And just to confirm this is measuring from ground to pin 3 on each IC? You have been super helpful. Sorry for not following some bits. This side is all new to me. Give me a regular amp and I can build/fix it but the triaxis is a bit fancier.

    Triaxis Optocouplers, LDRs, Relays

    Just measuring now with all the BMT set to 4.5 I'm getting IC1 - 4.82M IC3 - 3.66M ic5 - 49.2k IC7 - 2.04k (can only get a reading with it on 0) IC9 - 3.48M most adjust with increments. I have swapped the two tl072 with ones from other spots such as dynamic voice and still no change. The...

    Triaxis V1 Calibration

    Hi, My triaxis BMT controls seem to have very little effect on the sound. I have replaced all valves and no difference. I have looked up the triaxis calibration procedure but my unit seems to be reacting differently. I entered calibration mode via the factory reset and it says everything...

    Triaxis Battery Drain Issues

    Right guys i've been banging my head against this for ages now. I replaced the entire backup circuit and it still did it. So i thought i'd experiment a bit. I got a FM16W08 NVRAM chip and a SOP28 to DIP28 adapter to match the form factor of the 6264BL that the Triaxis uses. Installed this &...
