In what way have they been problematic? I'm not sure what you mean by "Wear indicates performing well repeatedly."

My XL-7 is actually a PX-7 in disguise. My original XL-7 mainboard exhibited a problem whereby one would get clicks in the audio out when the machine was running warm (i.e. in my studio in the heat of summer). It turned out I could get a (used) PX-7 for the same amount it would have got me to get a replacement mainboard shipped from EPR electronics, so I did that and swapped the lower half of the PX-7 with my XL-7 and put both the XL-7 and PX-7 ROMs in the unit. I now have a spare unit which can be handy if some front panel item or the power supply fails. The only downside of all this is that the XL-7 now says "PX-7" in the display upon starting up. Not a big issue. Would be easy to fix with appropriate software, apparently, but only service facilities such as EPR can do this, on-site, which would mean I'd have to ship the board to EPR and back again...

(Yes, I could have moved everything to the PX-7 instead, but I like the XL-7 front panel graphics and color scheme better, and besides, the XL-7 parameter wheel had a better feel to it, being more worn (easier to turn)).
