WOW I spent many hours of my youth with hard headphones on listing to my HW-18. When I got out of CAP I gave the Rig to the Lapeer squadron in Michigan.
I found one on eBay a year ago and could not stop myself from putting a bid on it, well as ebay goes I now own it. I purchased a internal DSP board and I am going to turn mine into a external speaker (I am going to make the lights work and if I can without screwing up the audio I am going to have the audio tickle the S meter.
I am telling you all this to say if you need some parts I plan on removing the guts of the rig, if you want the parts I will be happy to sent them to you. (except the swithches, s meter, speaker, volume controls.
I DO NOT have a power supply but they are available on ebay all the time.
Mine was on 4604 KHZ
