[Amps] 4CX1000A for SSB??

[Mark Marsden]

Hi Peter
 
No it doesn't use any feedback. The schematics are in pdf form on the
website, just a tad out of date now that I've changed the pi tank.

Do you use any negative feedback?  It looks pretty good to me, but it
would be interesting to drop in a 4CX1500B, which is supposedly more
linear and see if you can tell the difference. I know, the problem is
getting one!
 
I presume there's tuner used on 80 and 160, which would push the
harmonics down further.
 
All in all, Mark, very interesting and useful information.
