[Amps] Alpha 374A ?

[chas]

The 374A being a typical tube amp, I assume that it is NOT going to be 
capable of tuning in the MARS portions of the various bands to include 
30 and 60meters without a lot of effort from my Dentron MT3000A.

The only amp that I am aware of which will tune continuously, all freq 
from one end of the band plan to the other, is the Henry 4K Ultra (and 
that is limited to 3.5-30mc).

Now I am hearing that this is also true of the 374A in spite of my 
reading of the manual.

How well does the 374A handle 60 meters?

what output should I expect with a set of 3CPX800A7s?
what is the warm up time for this tube?

any other comments on this amp vs my fully modded Heathkit SB220?
iow, considering the difference in prices between the two, is the 374A 
going to be worth the extra $$$?
