MOTM

Frequency counters in most sub-$200 VOMs are not very accurate, especially
at audio frequencies.  For $70-$100 you can pick up from ebay an old HP
frequency counter 5314A (labeled "Universal Counter") that has pretty good
accuracy, to 0.1 Hz.  It also has A/B inputs for ratio comparisons, so you
can tune oscillators perfectly to octaves or any other ratio.  It's great
for tuning to perfect ratios, for instance a perfect fifth is 3/2 = 1.5, and
a perfect fourth is 4/3 = 1.33333, etc.
