this is just a question:
i just got a furman spring reverb rack thing and it wasnt working right and i opened it up and there is that amber-looking gunk all over the PCB solder joints.
an amp i fixed recently had the same stuff that was causing intermittent noise and when i cleaned it, it got all better.
now what IS that gunk? and why sometimes when i re-flow solder on an older board does it seem to appear?
is it rosin? but if it is, is it bad? it certainly seemed to be in the case of the amp....is it nicotine (i think roly maybe mentioned that) or other noxious residue? or just oxidation?
just curious.....
