[AMPS] Additional Tube Brand Questions

[Phil Clements]

The best L4 was the first L4 without the B thad had EIMAC SK sockets and
chimney. Great.

This is about the time chimneys doubled in price as well as blowers and tank
components. This is when we started seeing key-down time limits in the ads
and manuals.

Eimac says that the useful power output of a pair of 3-500Z's is 1500 watts.
This assumes that you are using chimneys, proper anode caps, and proper
blower. I guess the 'muffin fan" users that have modified their amps with increased
anode voltage also have a big supply of tubes in the closet!
If the case is getting hot, this means that every component in the amp is getting
hot also....not good.
