I would like a copy of the article. I have an amp in process-gathering parts
now-was thinking of 4 572B's but 813 is good tube.

> Hello All,
> The thread on final circuits has been great to follow especially with the
mention of 813's.
> It is still a very cost effective tube and in good supply NOS since the
audio crowd has yet to make much use of them.
> I have a copy of GE Ham News from Nov-Dec 1959 that features a "Kilowatt
Grounded-Grid Linear Amplifier" to quote the cover.
> It uses a pair of 813s GG with a standard Pi Net output configuration 5
band switched 80 -10 mtrs.
> Looks real easy to build and with the exception of the B&W filament choke
FC-15, I have most of the needed parts or
> can find them. The construction article is well documented and pictured.
> Is anyone is familiar with this amplifier or better yet knows of one
being built? If 160 meters would be easy to extend to with more L & C where
needed then it would work well for anyone with a good drive source.
> For those that do not have the Ham News Issue I can scan a copy and e-mail
> Thanks for any info,
