I presume that was a typo. Does anyone challenge this? What is the
effect of different modulator current values. Changing it risks
breaking the wire on that resistor... which BTW, Rick sent to me as a gift.
Why would Johnson change the value so drastically from one manual to the
next?
Does the 6l6 have anything to do with my problem?
