A While back I bought Dick Smith's ESR meter. I tend to find that somethimes, more often than not the old caps don't really have poor ESR coampared to the new one( i tend to spurge for the best).
Case in point, Klark Tektik D780 Reverb(1980's) caps in the power supply were lower ESR .2 compared to Panasonic-NHG .36 -
This is one scenario but other units I knew needed to be recapped because of humm/noise, showed that caps wern't too leaky. I changed caps anyway and the unit sounded f#@ing great and quiet.
Any ideas?
bad ESR meter?
old caps had fine ESR but no capacitance anymore?
