I found this on the Heath reflector and could not
resist forwarding it to this group. I guess the
devil made me do it, but this just looked like
the perfect group to take care of this chap.
Cheers!

Does any one know the reason why Heath would chose to float the grids
above
ground on the 500z tubes. they are bypassed for rf thru a couple of chokes
and capacitors, it seems to me it would make more sence to ground them
directley to the chassis, for better isolation and stability. all bias
and metering is
suplied thru the center tap of the fil xformer. Thanks Dick K6KWQ
