Yay!
Looks like you resisted the temptation to look at the innards?
Looking forward to hearing whether it makes a difference - hopefully after all that!
Well it took some time (7 months I see ) but today I had a look inside of the SR7 because I wanted to increase the voltage of the output feeding the sMS-200 to 12V. I temporarily powered it using the 9V output which used to previously power the downstairs FMC. I temporarily switched that one to the 7V output previously used for the microRendu. That 7V output is now at 12V.
SBooster recommends running the sMS-200 at 12V so I thought let's do it. I love free and easy tweaks! The sMS-200 sounds/operates best at 12V because of it's internal voltage regulators/converters that emit lower noise at higher voltages. They work a bit different than those inside the microRendu which only heats up more when one increases the voltage.
The adjustment was an easy job, just four screws to be able to remove the top plate to get easy access to the potentiometer on the board of the corresponding output and with my multimeter connected turned the screw several turns until instead of a 7.00V a nice 12.00V was displayed.
There's a sMS-200 'Ultra' coming by the way (expected for April 2017) having upgraded clocks based on the SoTM sCLK-EX clock board. Also other very interesting findings were shared on CA by Romaz.
