They are in the meter cicuit...and if they are wrong..the plate current will 
not read correctly...and of course the current on both tubes will not be matched

Subject: [Drakelist] TX4B cathode resistors



The two cathode resistors in the finals in the TX4B should be 15 ohms each, but 
R32 is 30 ohms and R33 16 ohms with the finals unplugged, so R32 is definitely 
bad. The difference in voltages on the cathodes of the two finals is, however, 
minimal. The voltage across R32 is 0.85 and 0.7 across the R33.
What are the causes and consequences of the differences in the cathode 
resistors?
Thanks.
