[Heathkit] Differences between HG-10 and HG10B VFO?

[Bwana Bob]

Dave:

I never did any measurements, but its pretty stable. Like any  vacuum 
tube design, it pays to let it warm up for about 30 minutes.  Heath paid 
a lot of attention to stability issues. hey used good quality 
capacitors, and ceramic coated inductors. Also, there is an internal 
regulator tube.  When I did have stability and chirp problems, it was 
due to a faulty 6CH8 oscillator tube. Some tubes will oscillate fine but 
will chirp on the higher bands and will drift when keyed. Try to find a 
couple of spare tubes, just in case.
