I'm using the HF amplifier kit from Minikits; works well on 50/70MHz. You'd have to adjust levels for good linearity.

It also does 6M and 2 M although the input matching may need tweaking.
So my question which ones do I need and where do you get them?
RA60H3847M1 RF Module 60W 378-470MHz for 70cm
RA18H1213G RF Module 18W 1240-1300MHz for 23cm
For 2m have a look at M0DTS web page. http://www.m0dts.co.uk/index.php?tag=146MHz
Roberto Zech DG0VE https://www.dg0ve.de/en/ or Bert Modermann PE1RKI http://www.pe1rki.com/ for ready made units.
I was totally confused with the M0DTS site!

Also this link on the M0DTS site for a 2 metre PA.
