Yes, I noticed this first time when I brought the amp home and played with lower volume level. However, before that I used the ch2 always in vintage mode and never tested the ch2 modern with higher volume. In the local Mesa store where we tested the amps, the volume level was already higher that...

Hi, I noticed a serious issue with my 3ch Dual Rectifiers channel 2 when using the modern mode. When turning the Presence all the way up (It starts already at 12:00) it kills all the high frequencies from the signal and makes the amp sound like playing under water. Clearly a fault, no amp...

Is that change done when EU is formed? I found this link: http://www.gbaudio.co.uk/data/mains.htm which seems to say that the upper limit of the new voltage tolerance in EU is about the same as the upper limit of the previous UK specs. The TA I have is from somewhere around -95 (SN32xx), so is...

No, The USA and EU Triaxis have different transformers. In both of the versions it seems to have two wires for different voltages 100/120 and 220/240. So, if you buy TA from US you need to change the transformer or use a 220->110 converter. I called to Mesa to ask about the power supply issue...

Thanks Supramax for the comment. I received my TA from service and they said that there is nothing wrong with the unit. Ok, That is fine for me as I haven't compared it side-by-side with another TA to check that it sounds just as it should. Anyway, what was slightly disturbing was that the...

I seem to have wierd problem in my Triaxis. It sounds a bit noisy (50Hz Hum) and I have a feeling of lack in gain. I have suspected the power supply capacitors but now I noticed that the transformer is wired so that the 240V node is used in the circuit board. (The thermistor is connected to...
