That's difficult due to the 12V requirement. To do it right using 12V capable transistors/FETS would take at least two and probably four amplifier boards similar to the KPA500 with associated splitters and combiners. *Without tuner and power supply* would put the price somewhere north of the KPA-500 just because of all the controls, heat sinks, etc. There is a reason that 12V capable transceivers do not run more than 100W output (typically 2 x 60W or 2 x 80W transistors in push-pull). 73, ...

I would gladly donate my ALS-500 to Wayne and Eric so they could see how not to build one.
