Heathkit A-9C Integrated Tube Amplifier, Working Unit. This is a mono amplifier so you will need another for a stereo system.
I have checked all of the tubes and they test strong. Controls have been cleaned with De-Oxit. Hooked it up to a speaker and an Ipod and listened to it for about 20 minutes. Nice sounding unit and all controls are working as they should be. Under the chassis, it appears to be all original.Here is a short video of the amp in operation taken a few days ago. Power output: 20 watts per channel into 8? Frequency response: 20Hz to 20kHz.
Input sensitivity: 10mV (mic), 7mV (MM), 80mV (ceramic), 600mV (line). Tube complement: 12AX7, 12AU7, 6L6G, 5V4G. Dimensions: 14 x 8 7/8 x 7 3/8 inches.All tubes are tested on my calibrated TV-7/B or on my calibrated Hickok 539C. All of these tubes have been tested for transconductance, shorts, gas, leakage and life. If you have not already done so, please take a moment and look at my feedback.
All tubes are 100% guaranteed good on arrival. These are great tubes for your new audio gear, guitar amps and vintage stereo/audio gear.Please check out my other auctions.
