 Ameritron Al-82 amp $1500  
Sticker date 2/14/11. I purchased this a little over a year ago from KI5BTQ with the hopes of running 220 from PowerPoint into my house. Due to complication and my ex passing away a lot has changed and I dont see the need for 3 amps as I have an 811H and an AL80 that tom has just gone through. Amp was tested on multiple bands and full output. Just trying to get money back I had invested in this and havnt had the time or money to run 220v. I prefer not to ship but will at buyers expense. Can meet when work allows within a reasonable distance to Collins, MS. Has been covered up since purchase. Check my reviews as I do a good bit of selling and buying here and on ebay. Most all forms of payments accepted. More photos available upon request, took cover off to get photos of insides. Prefer text messages for communications but any for will work if necessary
