Walked into GW yesterday, looped past the electronics aisle and saw something almost pioneer champagne series-ish....got closer, MCS 3237 $4.99. picked it up in a perfect baton handoff and went home.

It works.

should be a quick and easy restore - got the SCM from hifi-E and while it works, every part is a simple sub.

HOWEVER....what is the idle current setting? has a VR for both sides and emitter resistors with places to hook up a meter...anyone know the proper voltage I need to dial in? striking out on the net...

and after a complete tear down, cleaning, recap, refurb you name it:

In case this is ever found....struck out on bias settings, BUT, found 5.1 L, 3.9 mv R so I split them at 4.6ish since that seemed to work after consulting with Mr Vince at Galaxie.
