SB-102 mic level

[Emil Dular]

Clear up my thinking for me if I don't have it right. If the problem were 
low meter reading rather than low audio drive wouldn't a wattmeter show me 
with unsuaully high output rather than about the 105 watts I expect to see?

If instead of the 210 milliamps the meter says are going to the finals it is 
really 250-275 or more that I'd expect to plates in the finals to light up 
furnace red.

Not to say the shunt resistors might not off, but wouldn't you see other 
symptoms.?
