Freeze Sprays

[ld]

it is simple..some parts will be intermittent with temperature..when first
turned on they will be cold and work but as they warm up they become open
circuits..so after the synth has been on long enough to be fully warmed up
and in failure mode spraying the suspect parts will cause them to work again
for awhile easily confirming their defect..likewise with solder joints.
