RD series
Rob M0DTS published an easy to construct design using the RD series of FETs in CQ-TV 247 and 249 - a good way to get a clean 5 watts on 146 MHz. (The full article is available in high resolution in the magazine)

Mitsubishi power modules
The Mitsubshi RA60H1317M 60 watt brick can be driven via the YU1LM filter and a 10 dB attenuator from the Portsdown transmitter to provide approximately 7 watts output.
Ready built amplifiers using this module are available from Bert Modermann PE1RKI http://www.pe1rki.com/
For those who want to roll their own the following were published:-
- Sam Jewell G4DDK, 8W 2m amplifier.
