[Amps] 6C21

[Barrie Smith]

Carl & Roger:

I'm really not arguing with you here.  However, comparing a 6C21 to a 750T 
runs contrary to what I know about the tubes.

An older, local ham gave me a NIB pair of 6C21s about 25 years ago.  In the 
early 1990s I built a push-pull transmitter using the pair; modulated by a 
pair of 304TLs.

I used a data-sheet written by Bill Orr when he still worked for Eimac.  It 
clearly states that the 6C21 is comparable to the 450T series of tubes.

450 watt PD in CW and 300 watt PD in AM phone.

After reading your recent posts I thought I may have missed something, so I 
went into the basement and compared a 6C21 to a 450TH.  The 6C21 has a 
sturdier grid lead and a chrome plated base.  Other than that, I see no 
differences between the two tubes.

The anode is certainly no larger or snmaller in either tube.  The base and 
socket are the same.  The physical dimensions are the same.  Filament 
voltage and current (according to the Bill Orr spec sheet) are the same.

So?
