Quad was the early version of surround sound,
using 4 speakers,
like a front and rear stereo.
and only one AUX input.
no FM, tape or quad synthesizers.
Very intricately built,
there was no way I could afford a professional repair service.
and finally I was able to get down to business.
The insides were unmolested and original.
The first clean was done outside,
compressed air to blow out the dust,
and each pot (knob controller) lubed and twisted 50+ times,
usually all that's needed.
The thing was dead!
Did I pull a wire out accidentally?
Short something out?
There was intermittent clear sound when the speaker knob was inbetween the A & B setting.
Out of frustration,
the dormant 9090 was hooked up,
and wow at 110+ wpc it cranked those speakers.
1030 pm was the start of the 2nd clean,
this time inside huffing all the good chit.
Old sansui's were known to have flux build-up on the boards,
and I chipped off a bunch with toothpicks.
Like that would miraculously fix it!
After a more thorough spray cleaning,
and sufficient drying time,
the test speakers were hooked up.
All inputs, FM, quad buttons and A/B/front/rear!
Nothing perpetuates a rattlecan rebuild hack fix like success.
probably more so with the fumes.
Did the couple midnight celebratory tequila shots sober us up or help us wind down?!
