Maas-Rowe Carillon Amplifier
#15

I don't have the exact schematic of this amp.  Paul Rowe of Maas Rowe is looking to see if he has one.  However, it is very similar to this 500A schematic except that the 4 6L6's were replaced by 2 6550's.  Can someone splain to me function of the 6V6 in the screen grid circuit of the 6550's?  I would assume it is some form of regulator for the 6550's (6L6's).  Perhaps protection for excessive output?
