[Kenwood] TS-850 serial numbers

[Dave]

Matt

I've owned two 850's over the years, one of the best CW contest rigs ever 
mass produced. To be sure the  TS-850 has a few warts (VCO2 setting cap and 
the ALC board failures) which are chronic potential failures through out 
the life of the product.  I don't believe there were however any major mid 
run changes such as those seen on the TS-930 (I owned two of these) and the 
TS-870.

As a matter of good preventative maintenance IF I were buying the older 
2XXXXXXXX unit (manufactured in 1990) , I would replace the memory backup 
battery immediately (unless the previous owner can atest that this had been 
done in the last couple of years) to reduce the risk of damage to circuitry 
in the area caused by leakage of older batteries another often reported 
problem on older 850's

Good luck
