Re: [Amps] Designing the Cleanest Linear with RF Negative Feedback

["Peter Voelpel" <df3kv@t-online.de>]

Hi Tom,

I put diagrams of the Harris linear and the Racal widebanddriver
on the following website:

http://www.pbase.com/df3kv/gallery/linear

By the way, 
the TA1800 also uses 10db of negative feedback, but just to the driver
stage, not to the pre-driver.
All stages run class AB1, except the wideband-pre-amp which is class A.
25mW -> wideband pre-amp 250mW -> pre-driver 4CX350A 2.25W -> driver
2x4CX350A 113W -> 4CX10000D 10KW.
The 4CX350A get their 1500V anode voltage from the screen-supply of the
4CX10K, clever!
