That "safety" device can easily destroy your PS and I always disable/remove
them and add a warning label.
If you are that worried about safety then add a cover switch to disable the
AC line as many other amps do. Very simple and inexpensive.

Subject: [Amps] Looking for picture of SB220 interlock switch
I'm preparing to start on an SB220 renovation project:
replace capacitors, update diode board, etc
The previous owner has disbled the safely interlock by
bending the brass strip away and removing the
"tapped phenolic spacer". I'd like to restore them.
I'm not sure what, and why, the machanical and electrical
parameters are of the spacer as I'll need to find something else.
I'd expected it to be a metal thing but according to the manual
it isn't.
Does someone have a detailed picture of the interlock in place?
Why is it an isolator? What are the mechanical stresses on the spacer?
73,
Geert Jan
PS: I know the interlock doesn't make it safe, but 'safer'
and that's still a good thing IMHO
