Building an amp!
Its always a good idea to select a tube that is twice the power out you plan to use and run it at 50%. This keeps it linear and very clean. A good linear amp should be no wider than the driver and in fact harmonics should be lower after the amp if it is well operated, designed and constructed.
Many people have used old commerical tubes where the tubes are taken out of service as there performance has dropped below spec. The only thing to be aware of is the higher than necessary filament consumption. Grounded grid is ideal with some of these old tubes as its easy to build, very stable and clean. Some of these old tubes are advertised from time to time on www.trademe.co.nz

NZ has a legal power limit of 500 watts PEP - Canada 1KW. This is only 3db of gain or 1/2 an S point increase.This difference is easy to match with 3db gain in the antenna. A 15db gain antenna and your 500 watts PEP is now 16kw PEP eirp. But there's more - you also get almost 3 S points or more on recieve.The people with high gain antennas are the ones everyone can hear but more importantly they can hear everyone else. Because there is only 3-5db difference between NZ power limits and that of many other overseas Countries, it becomes easy to spot those running high power with low gain antennas as they have big mouths but deaf ears.Message - Focus on big high gain antenna arrays if you have the space. I know many hams in the Cities don't have the room but even a 1/2 wave slopper can give you 6db of gain. That alone takes your 500 watts PEP to 2kw eirp. My 1500 foot antenna array on top of a hill gives me all the gain on transmitt and receive I need. (15db gain on the upper HF bands) Check out the playbacks I provide and you can hear the big antenna recieve gain. It is 4-5 S points over a dipole. Do the math and good luck with your high gain antenna arrays.
Many are confused about SSB PEP power verse the power measured on a Bird Watt meter.
500 watts PEP / 2 *.707 = RMS power 176 watts
176 watts /.707 * 2 - 500 watts PEP
600 ohm open wire spacing - dia of cable X 75
100 watt TV Peak sync TX shows approx 62 watts on a Bird Watt meter on black screen ( ie no video)
