[AMPS] Parasitic suppressors/another question,

[jono@enteract.com (Jon Ogden)]

Rich says:

>100% increases in R-supp after bandswitch arcing?

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?
