I see on Ebay Yaesu power amplifier boards with 2 and 432 modules mounted with the heatsink. A few relays and your ready to go. Mike

I have been trolling ebay looking for a linear amp capable of taking my 2W output from my IC-402 bookcase rig and get it up to around 20-25 W.

I have found this: https://www.ebay.com/itm/400MHz-470MHz-25W-UHF-Ham-Radio-Power-Amplifier-For-Interphone-Car-Radio/121409629932?_trkparms=aid%3D1110006%26algo%3DHOMESPLICE.SIM%26ao%3D1%26asc%3D20201210111314%26meid%3D4b7474922b8a4a86bd204059544d5e9b%26pid%3D101195%26rk%3D8%26rkt%3D12%26mehot%3Dag%26sd%3D112544232673%26itm%3D121409629932%26pmt%3D1%26noa%3D0%26pg%3D2047675%26algv%3DSimplAMLv9PairwiseUnbiasedWeb%26brand%3DUnbranded&_trksid=p2047675.c101195.m1851
