[Amps] ARRL Amplifier book

[Bill Coleman N2BC]

Pete, the Harris RF-110A / RF-124 meets most of those requirements.  With 
careful shopping, one could have 3 or 4 (or more) Harris setups for the 
price of one new Alpha 87.

It covers 2 to 30mHz in 19 bands, no tuning. The Harris can easily be put on 
160M with a minor tweak.  It runs a pair of 4CX1500s driven by a pair of 
8122s.  Requires about 100mW drive.  It can be driven from most rigs 
transverter output thru a 1W broadband amp or from a 100W rig thru a 30dB 
attenuator (readily available on the e-place).

The negatives are it's noise (an 11,000RPM fan), and size (~300 pounds in 
two 10.5" rack mountable cabinets). It's rated at 1KW output, will easily do 
more but I wouldn't want to have to fix a toasted tank assembly.

The pluses are it's easy to control it remotely with a simple home-brew 
control head - move the noisy beast into the next room. It's quite 
serviceable, slide-out drawer, etc.

I have some words and pix of mine on my home page:
