[Central-Electronics] Amplifier for CE-20

[W2HX]

why is the 600L a better match for the 20A than the 100/200V? I always
thought since they were in very similar cabinets (600L/100/200V) that they
were designed to work together.

And while on the subject, anyone have a nice condx 600L to sell? Has to be
nice (to match my 100V) and in good operating condx

thanks!

Tom,

     The best choice here is the CE 600L amplifier. It is a better match 
to the 20A than it is to the 100V/200V series exciters. If you are 
looking for something cheap, look for a Dentron MLA-2500 with used up 
finals. These amps are sometimes cheap, work 160M, and are ripe for a 
wide choice of tube substitutes. If your real lucky, you might find one 
with just one dud tube. That would be almost perfect to your needs.

    I have a MLA-2500 here, and I shoe-horned a 8877 in there. The gain 
is about 13 db, and a 20A gives about 15 watts PEP (depending on the 
band - 40, 15, 10 less), so 15 watts with 13 db gain provides 300 watts 
output.

    If your into home brewing, a single, or dual 813 amplifier (grid 
driven) would fit the bill nicely, and do so on a budget.
