I have for sale my Henry Tempo 6n2. This amplifier has an output of a kW on both 6 and 2 meters. The desktop unit contains both the RF deck and power supply.

More if I push it. This one gave me a lot of trouble, I followed the modification instructions from the internet.

Inside top view Power regulator section, this was where the problem was. Automatic tuner Finals heat sink and cooling fan. Transformer and power supply.

The amplifier does not have an internal antenna switch over relay so you have to add an external relay to switch the antenna over AND switch the tube bias, wonder why they did not add an internal relay? Anyway, I have a few relays but need to make sure I have one that can handle 1kw of VHF RF! So it will take a while to get it going. Homebrew HF amplifier with 4-400 My first attempt at a completely home-brew amplifier, the 1 x 4-400 tube give me an easy 'legal limit' (South Africa) output on all HF bands.

I have not used this amplifier for years, I think the last time I did was when I used it in a contest, and I have not run a high power contest since 1998! This amplifier will run 1kw with 100% duty cycle in any mode for as long as you want, it was used by embassies for RTTY, CW and SSB in the days before satellite telephones. Update:I decided to check my TW-1000 amplifier and prepare it for use. I decided to connect PTT and ALC cables internally to the controller rather than the 12 pin external plug, I plug I could never find and I was not happy with my previous temporary arrangement. I must say I forgot how heavy the amplifier is, around 40kg, everything is super heavy duty including the internal 120A 28V power supply! This amplifier is a thing of beauty, I normally prefer tube amplifiers but this one is special.

Metron MA1000 Solid state amplifier Inside of the Metron MA1000, it uses 8 x MR 454 transistors, you can also see the relay switched band pass filters. In the above photo you can see that 2 of the relays are open. As standard maintenance I always clean T/R switching relays on all of my amplifiers on a regular basis. Fischer F70 New I finally found time to go and fetch my new 70cm amplifier. It is a Fischer F70. How to play the klub 17.

My main power amplifier is a Tokyo Hi-Power HL-350VDX that puts out around 300W PEP. I do have much more available using a pair of 4CX250Bs, which I use on special occasions. It is not practical to run very high power most of the time. All my high power amplifiers use valves and they tend to be noisy. The amplifiers get used for contests and special expeditions.

It just sits there with it's quiet fan producing lots of power without any fuss, I am glad I added this amplifier to the shack. Yaesu FL-2100Z This amplifier uses 2 x 572B tubes and is a classic from Yaesu. This amplifier had been the work-horse in my shack for a long time, since we have a 400w power limit it copes well and has been reliable. Heathit SB-200 Amplifier using 2 x 572B tubes.
