[AMRadio] Grounded grid amp

[Bernie Doran]

glad you spoke up Phil, you probably remember the upside down ones.   I had 
a pair of PP 304TLs driven by a 20A, very easy to drive with 4400 volts on 
them.  also had a 75A4 and still have it, I am the original owner of it and 
second owner of a KWS1 that I got around 1958 or so, always thought it would 
make a nice driver for a bunch of 304TLs in gg!!!  hard to believe that I 
remember some of the old stuff and I am close to 50 years old!!.
