Counterpoint SA-7.1 phono/RIAA settings?

I have a Counterpoint SA-7.1 that I am bringing back into usage.  It was owned since new (over 30 years). Asking this question as it is not a straight, stock S-7.1.
Around 25 years ago, I sent it in to Counterpoint for a rework where they may have UG'd it to a SA-1000 circuit (I don't remember but I do know the line stage was reduced to just a 6DJ8 tube).  I didn't use it due to a change in life until 11 years later when I powered it up and found the amp was dead and didn't feel I needed to pay Alta Vista quite a bit to further UG it.. 

Earlier this year, I opened up the amp and found that there was a leaking capacitor.  Replaced it and it's working.   Now I want to get a new turntable (found my old LPs).

Question is, the SA-1000 has a setting for MC or MM cartridge usage.  Does such an option exist on this UG'd SA-7.1?

my best guess is that a reduction of the line stage to just one tube did not affect the stock tube RIAA circuit description. It’s a totally different part of the circuit.

So whatever the original phono circuit was capable of re the manual’s wording, this would be very unlikely to be changed. Mike Elliot would not have failed to have informed you of any change in the RIAA use or settings.

(previous owner and rebuilder of at least 5 counterpoint components)(not an appeal to authority, just showing I've dealt with Mike directly back at the time, and had my hands inside the gear)
