I say:
So the bandswitch arced. OK, I'll give you that it could be an
oscillation. But how can you say that Rsupp increased 100% AFTER the
bandswitch arcing? Did you measure Rsupp BEFORE the bandswitch arc
occured? Or are you making the *assumption* that the resistors were good
beforehand.
Perhaps failed resistors (due to heat, age, etc) in the suppressors
casued the amp to oscillate thus destroying the bandswitch.
>From what I can tell, one has NO way of knowing the condition of the
resistors prior to the arc. Visual is not good enough.
What do you make when you ass-u-me?
