AMPVHF - 500W 2m 144-148mhz Amplifier Here is a hand built 500W 2m EME amp. It was built here in the US from European DX World boards and Japanese NXP LDMOS finals. It’s a high efficiency amplifier with its own internal 60V power supply. It has been professionally modified with input protection, and 12-15W will easily get you 500W out (but you can adjust the input bias and get full power off an 8W handheld). The base is a very large aluminum heatsink mounted below a copper heatsink, and at the rear are two 3”constant speed axial exhaust fans, which allows quiet operation. I’ve tested it for full power out which it easily achieves, and below are photos showing how just a couple of watts in generate 93W out. This is the 2m version of the HF amp that DXWorld lists for 1400 EUR plus delivery. *Asking $900 shipped CONUS.* Zelle/Venmo. Will be shipped double boxed with all documentation and schematics.
