FOR SALE: SPE 1.5KFA Amplifier Series 3: Due to medical issues this past year, I am selling my SPE 1.5KFA Amplifier Series three in mint condition. I am the original owner, and it is still under warranty until Dayton 2026. This was one of the last series three amps made before the Taurus. There are two inputs and four ant outputs. It also has a built in coupler for PureSignal. The internal tuner will handle up to a 5 to 1 SWR! I am asking $4995 or best serious offer. I would prefer a pickup so that I can demo the amp before you buy. It can be shipped at buyers expense. I have the box, leather carrying case, CD, all connectors, and warranty card. I can be reached by email or by cellphone at 609-351-0733. You can leave a message, and I will return the call. Thanks for looking.
