Hello everyone!
About a week ago, I discovered the Arcatron HDA-100 amp on eBay for $25 shipped through a liquidator. I got into a haggling war with the seller, whereas 5370H55V was able to get one very quickly.
This is the picture he took of the audio input.
What is this and how could we/he/I hook it up to a computer?
Thanks a bunch!
