<comes out from bushes> ah, that was me.
Was a great time and really a blast to dig into the Alto. We definitely
improvised, not having a stock of uA709 opamp on hand... we just bypassed
that regulator circuit and stuck a 7805 there instead, which was pilfered
from Vince Briel's spare parts stock for his
Altair8800micro kits.
Too much fun.
Good luck Nick and keep us posted.

Some GOOD news, at the Midwest VCF, Chris (from St
Paul, don't remember
last name) and Eric Kudzin were huge helps and took Jim S's
recommendation and repaired the 5V Op Amp fixing the 5V issue and now
the Disk Drive SPINS! We still need to repair the CRT and diagnose the
rest of the system, but we are making progress!!
Thank you Jim (for the amazing feat of properly diagnosing remotely via
schematics) and thank you Chris and Eric for your endless hours of help
at the VCF!'
I will keep everyone posted as we progress, Eric and I will be working
over the next several months to restore the Alto!
