I have one with the TX4 recto board. It was modded by Mesa boogie for extra gain on the LDY2. Basically it makes it a 2C++. It was also modded by boogie with additional switching functions. For example, I used an outboard GEQ with it and the additional nap switching let’s me turn on and off the GEQ via midi. It was also fully serviced last year and all lights are bright and it has zero issues.
I've got a buddy in Cleveland, TN selling a 2nd version Triaxis along with a Mesa 50/50, a power conditioner and rack for $1500. I dunno if that's up your alley.
