From: N_Cook on 30 May 2010 06:20 Translucent appearance, so can make out form but not detail of components under it, same when new. There is also iron rust brown colour as well as the green. If it was a mixture of paraffin wax or petroleum jelly and silica gel I could see the silica taking in water and the other breaking down to an oil. -- Diverse Devices, Southampton, England electronic hints and repair briefs , schematics/manuals list on http://diverse.4mg.com/index.htm
From: N_Cook on 30 May 2010 13:21 Didn't work , I'd not noticed one of the pyro TO5 size leads was corroded through. So much for Racal RLC1/2 , opened up a used working Racal IR771 with a RPY96 (same spectral response) and LM324 to play with, no conformal around that one -- Diverse Devices, Southampton, England electronic hints and repair briefs , schematics/manuals list on http://diverse.4mg.com/index.htm
