:>From: "w7ry" <w7ry@netzero.net>
:>It is a Viewstar....And yes, it covers 160 meters.....
:>Last one I had I sold it for $ 800.00

Hi Jim, 
-
Compared to today's "Ebay Prices," it went pretty cheap. I'd 
like to get a look/copy of the circuit diagram if anyone has 
one to share. 
-
:>They work good, but some have had trouble with them.
-
There are a series/generation of HF amplifiers produced in 
the 80's and 90's which are similar in appearance, but 
their Engineering and Production Origins are a bit vague to 
me.  The Viewstar and the B&W Amplifier along with one or 
two others appear similar in construction, but probably have 
different roots. 
Carl, km1h was reselling the B&W amplifier for a time, I'd 
never heard of a Viewstar vender, and there is also a 
"Palstar" amplifier..?  I would assume none of these 
amplifiers lines are still in production..?
-
:>They run 4000 volts on the plate, very easy to tune, with nice Jackson
:>Brothers drives.
:>Has a squirrel cage blower and glass chimneys..
-
Were these amplifiers plagued by any the classic dual 3-500z 
construction format "glitches" ... (parasitics, cooling, high 
filament voltage, power supply heat) ..?

Thanks for your input Jim...

I just found/bought an old home brew dual 813 HF Amplifier, 
just because of the hand made output tank cap physical 
hardware makeup.  The original builder made a really wild 
low end range band switch lever mechanism which moves 
a plastic square with a metal end attached to slide over and 
short the two halves of a center parted surplus air variable 
capacitor.  
-
Just the mental work to come up with this hardware was worth 
the fair price I paid.  After next Thursday, pictures of this wacky, 
but well working hardware can be seen on the 
http://sonic.ucdavis.edu  Amateur Radio Pages. If nothing else, 
it's good for a head scratching laugh. 
-
Anyway... anyone with a Viewstar Diagram to share..?

cheers
