Howdy,
I see the QRP kit, MiniBoots--a little 5W linear is not being shipped anymore. Is there anything else out there that is small, kitted, and somewhere between 5 and 10 watts?
Thanks,
Jonathan KC7FYS

Please visit this link:

http://www.kkn.net/archives/html/QRP-L/2005-06/msg01204.html

It may not be EXACTLY what you want, but I'll bet the info there will be close.. at least give you a starting point...

oh, by the way, a Google search on MINI BOOTS turned this up.

Hope it helps.

The Miniboots kits may no longer be available, but they still give you the schematic and parts list. You can homebrew one. If you insist on a kit, try:
http://www.ramseyelectronics.com.

The actual Ramsey linear amp kits are at:
http://www.ramseyelectronics.com/cgi-bin/commerce.exe?preadd=action&key=QAMP

The Ramsey amps come in 20m, 30m and 40m. They use a couple of power MOSFETS in push-pull to give you 10-20 watts output with 1/2 watt to 2 watts input.

If you Google "QRP linear amp", you will come up with the Ramsey kits and others.

Miniboots info is at:
http://www.amqrp.org/kits/miniboots/miniboot.htm

If you want to get even crazier with a homebrew amp, try:
http://lpistor.chez-alice.fr/pairf510.htm.

The page is in French and will need to be translated. It is instructions, schematic and parts list for a homebrew push-pull MOSFET amp.

Hi Jonathan,
This maybe more than you want; but, look up the HF-packer Amp. It is a multi-band HF amplifier, given two watts input it yields 35 -40 watts out. The output is lower when you get up towards 10 meters. It is a kit, the assembly instructions are on the web site. GL HTH
