[sdiy] SSM2164 protection

[Barry Klein]

Man, sounds like we are so lucky this nasty part is going away.... :-)
Reminds me of the Memorymoog timebomb in my garage.
Fix it, play it, put it in the garage for a while, get it back out, turn it
on and 4051's, VCA chips, etc. die.  Not to mention the tantalum cap on the
negative rail that may have caused it all.

Will do. I'll give that a shot this weekend.


Tim (good thing my 2164 is socketed... and I have about 300 of them) Servo
