PS: Unlike the ROMs used on 01 board which are Roland branded and soldered on. And good luck finding those masked ROMs in case it fails (not because of it's limited lifespan but for different reason - ie. ESD when you are fiddling inside of the MT-32).
So 00 revision definitely has a big advantage over 01 here.

You totally changed my mind. MT-32 revision 00 is superior! 😉

Seriously thought, the difference between the two is very minor. I happen to have one of each. I'm just trying to figure out which one to keep and which one to sell. I'm going to upgrade the firmware on the rev 00 to 1.07 and replace the electrolytic capacitors in both. Then put one up for sale.

If you have a tester, please post the condition of the original capacitors .

I don't have an LCR meter.

Complete cap kit is available here BTW: https://console5.com/store/roland-mt-32-mt32- … -kit-rev-1.html (it's for 01 but it should be virtually the same for 00).

Yup, Luke at console5.com has all the best cap kits.
