Just be sure you know exactly what you are doing. Don't call anyone at EC if you need help on the regulator mod or the regulator mod breaks something else. We won't service or field questions on modded amps.

That's certainly fair.  I was one of those dummies that forgot to label the internal cables before messing around inside.  Let's just say..bad things happened.  Ended up finding a guy to fix it at my own expense who used to be a tech for Cary Audio.  All that ended up wrong with it was a blown Zener dioide.  A testement to the practicality of Craig's designs. 

But I ended up doing to the cap mod successfully on my own.  May want to put that disclaimer in the Super 7 Mod thread as well if you haven't already.

Hey jwahl - Merv's warning is certainly not to be taken lightly. Diving into modding electronics is risky, more so with tube amps.

Warning aside though, this particular mod isn't super difficult and really made an overall improvement to the S7 performance. If / when you (or others) decide to attempt this, feel free to reach out if I can be assistance. Don't get me wrong - you assume the risk, but always ready / willing to share my experiences with fellow pirates.
