[Fox_Tango] FT102 finals

[fox_tango@mailman.qth.net]

Ive never mixed finals....proper neutralization is easiest and most complete 
with  matched finals...ie not just  tubes from  t he same mfr. but tubes 
within certain close tolerances  But Ive never had problems using  two new 
6146s ones  from the same manufacturer.    

Poor neutralization can trigger    damaging spurious oscillations and isnt 
worth the chance you take when mixing different tube types or mfrs  o rnew 
tubes with used tubes that have been thermally stressed.
