HI HI !
My preference in amps for whatever it's worth.
For contesting a N6UR homebrew 8877 or 4-1000A that loafs at 1500 watts
output, uses silver plated 3/8 copper tubing for 10 thru 20 meters and silver
plated 3/8 edge wound copper for 40 thru 160 meters...will NOT meltdown.
Vacuum tune cap is a must but a air load cap is quicker to move bands with.
The tuned input circuit is tied mechanically with the RF Switch Co. output
tank circuit switch.(Kinda sounds like a Alpha 77DX). In the case of the 8877
I do suggest a grid overcurrent protection circuit. These amps do have more
air going through them than probably necessary but for contesting maybe not,
anyhow they are somewhat noisey as a result. Headphones take care of that.
For general rag chewing and dxing I prefer the SB-220, no warm-up time,
quiet, near legal output, and they seem to run forever. With vacuum relay mod
they are much less noisey and even QSK if you like.
