[SixClub] 3CX1200 and 3-500Z

[Roger (K8RI) on Six]

I've been having a problem finding the tech sheets, but isn't the 3CX-1200 a 
direct plug in replacement (with external anode) for the 3-500Z? OTOH the 
3CX-1200 is *considerably* more money.

I finally managed to get enough together to either purchase a 6-meter amp, 
or build one.  I'm not fond of the glass 3-500Zs and although they seem to 
have the same gain as the 8874s in my old Alpha the 8874s go the legal limit 
with less drive. Unfortunately the 8874s are expensive, but I see there are 
now imported versions at a reasonable price.

Although not cheap I like the looks and numbers for the 4CX-1600B for both 
50 and 144 MHz.

Any thought, corrections, or suggestions.  One thing though, I'm not 
interested in modifying a SB220 even thought they are popular.  For the 
price they've been going, I just might try to find a three hole Alpha 76 and 
the imported tubes for spares.

I have a Henry 2K4 out in the shop that has a new set of 3-500Zs and a heavy 
duty Peter Dahl transformer.  It works well on 80 through 10, but it just 
too big to go in my den. I do need to replace the output sampling circuit 
though.  That and it puts out wayyyy to much heat.
