440 amplifier kits?
 

I've been looking around for a 70 cm band amplifier kit (to give my HT a
little more power), but can't find one. And it seems that Mirage (MFJ)
is the only company that even sells a 440 amplifier nowadays.

I found a few older 440 amps on eBay, but I'd kind of like to build it
myself.

Does anyone know a source for a 440 amplifier kit?

Thanks for your help.
