Hi, Im fairly new to vintage audio. I picked up a working KA-501 amplifier from the dump last year and spent the beginning of this summer fixing it. I got all the controls working and replaced the meter lamps with LEDs. I cleaned the entire inside, replaced the speaker terminals with 5-way posts and tested all the components with a multimeter. The amp is in perfect working and cosmetic condition, but is missing the front plastic side straps and the power paddle is broken off. I would like to know what a reasonable asking price would be if I were to sell it.
