This only happens when you press "entr"? Or also with other buttons? Midi control and such do work properly?

Send me a PB. Then I can send you you the schematic.

Does anyone have a working programming software to create presets on my computer and then send them to the Triaxis? I found the following site: https://triaxiseditor.com/ But I can't change my presets with this... or I'm not doing something right. Then there is this...

Bingo! So far the problem seems to be solved. The device responds to all buttons and to my midi foot controller. A faulty Z80ADART IC was the problem.

Is not necessary anymore. I already have it.

Sorry to brag about this topic, but isn't this the last version that also roams the internet? I see version C here. I think this is all schematic with the Deep Mod. See the choke already drawn. I would also like to have the schematic without this mod (version A ??)

I have seen a Mesa Boogie 50/50 second hand that has some problems. I quote part of the ad. "Only internally it is a different story. 2 years ago a transformer and a tube broke. I then had this checked at NEL and had a new tube inserted. Since I still play mono, I decided not to use the broken...

And, have you got your unit back? What was the problem? Keep us informed.

I finally succeeded in having the presets changed by removing the battery and completely discharging the capacitor. It has now shifted from "program" 25 to "program" 1. With the corresponding settings. However, the problem persists that it is not possible to change the settings. However, I found...

Stupid, ... Power supply of the TL7705 is on pin 8 and 4. Here I measure 5V. So the power supply seems to be good. Still something has to go wrong in the 5V circuit since the voltage regulator gets very hot .. Investigate further

I had just started measuring and I noticed the following. The 5V controller (7805) became very hot. +/- 60 degrees Celsius compared to +/- 40 degrees Celsius of the 7905. I found this remarkable. Therefore dismantled the metal shield of the CPU. I noticed that the TL7705 looks suspicious...

Yes I had indeed seen that link. Of course much is made clear there. But there should be an original schedule somewhere on the internet. I had already sent a message to the man from the YouTube video, but unfortunately also without a response.

Hi, I'm looking for the full schematic of the Mesa Boogie Triaxis. On the internet I often see the same schematic, but this seems incomplete. (http://guiguijones.free.fr/Electronique%20&%20Bouine/electronique/Schema%20Amplis%20Effets%20etc/Amplis/Mesa%20Boogie/mesa.htm#triaxis) I miss several...

A late response, but I also have the same problem. I was able to take over a Triaxis with the following problem: The display does not respond to the buttons. So all parameters remain unchanged when one of the buttons is pressed. As far as I have tested, the Triaxis also does not respond to my...

Hello, I wonder how the shielding of the cable from the input to tube V1a is connected. The PCB has a connection for shielding to the GND. But on the input side, the shielding is also GND. But this does not normally seem to be the intention due to ground loops. Does anyone have clear pictures...
