This sounds great , I have uploaded a video on YouTube ..just enter Kinergetics Research KBA-75 and it was posted today July 1 2023. I am listing this for parts and repair only because the power switch is finicky ..so I leave it in the “on” position and have been using a power strip to turn it on and off. Local pick up is welcome and if so, please message me through eBay and I will adjust the price lower. Otherwise , I will have this packed well for safe delivery within the lower U.S 48 only. Sorry, no international shipping. I will also pack and ship this for free. https://youtube.com/shorts/0PiovIaV6r4?feature=share Thanks!

Kinergentics Research KBA-75 Class A Power Amplifier (read description). Very highly regarded older power amplifier..unfortunately this has no sound output. The power switch was broken upon my recent purchase ..I had a friend replace the switch..and now what’s happening is as follows: The power switch seems to be stuck in the “on” position, so when I plug it in to outlet, the red power light comes on briefly , and I hear a “click”noise, but then the power light goes off. During this whole time , the standby light stays on (while plugged in).Cosmetically, there are various marks throughout ..please look at the pictures carefully using the zoom feature to determine as well. I will pack this well for safe delivery within the lower U.S 48 only. Sorry, no international shipping. I will also pack and ship this for free. Thanks! Note: if doing local pick up ( not too far from zip code 78132 TX) I will be able to meet for transaction and I will also adjust the price lower since I won’t have to ship this.. Thanks!
