The SR45 upgrade kit was a limited run that we did a few years ago. I will need to have a chat with PJ about whether this is a more approachable project now that we have updated some aspects of our kits, that might make for a reasonable way to put such a kit together. As we have just redesigned two amps (Paramount and SEX) and not so long ago introduced Stereomour I think our emphasis will be more towards preamps, headphone amps and possibly a guitar amp in the next few months.
