I would agree with Joe's recommendation. A 3-500z beats any number of 811s
any day of the week in my book. I have a box of 572b here (a much stouter
tube than the 811) on the shelf that died running within their specification
limits in RTTY contesting. I suppose that the 811 will do just fine if you
are careful. A 3-500z can take miserable abuse and still keep smiling
though.

Dick, I would suggest the AL80B instead of the 811's. The single 3-500Z
will last a long time in RTTY use.
You can get a used AL80B for about the same price as the 811.
AA5AU uses two AL80B for rtty contesting and he is a winner most of the
time

Many thanks to all who sent me an e-mail with comments on amps. I asked
about the AL-811 and 811H with comments ranging from "NO to anything 811"
to
"I have used a 811H for RTTY at 400 watts with no trouble." Almost all
commented on plate voltage requirements. I have 2 radios, YAESU Mark-5
Field
and a TEN TEC Omni-7. Looks like I will have to do some more searching to
decide which radio I want to use with the amp and what the radio/amp
requirements are best for me to use.
I had several suggestions about using other modes, such as the JT's Olivia
and PSK31 instead of RTTY. I tried PSK31 several years ago and found it
boring and not suited to my contesting use. I prefer to use CW and RTTY
and
not mess with other modes.
Many thanks for all the replies and information. Look for me in the RTTY
contests. Now back to the amp question for meJ
