[Heathkit] Suggestion for legal limit AM amp (was Heath Warrior as an AM amplifier)

[Paul Baldock]

I use a DX-60B driving a pair of 813's. I get outstanding audio 
reports. The 813's are running at about 2500V and comfortably give 
600-800W (depending on band) PEP, 150-200W carrier. I know this is 
way over the spec'd dissipation for 813's but I've yet to have one die.

I have my DX60B set to around 10W standing carrier, 15W average 
power, and 60W PEP.

The DX-60B would be a great driver for the Warrior.
