 Henry 2K Classic in Great Condition  
Henry Amplifier - 2K Classic
Henry 2K Classic amplifier is in excellent shape and my friend, KRØP, just went through it - I have not used it for almost 15 years since I bought it and it is an awesome amp. Has two 3-500Z tubes that are working well. Can use 60 watts up to 100 watts to drive it. It can put out up to 1,500 watts PEP. Wired for 220 volts. Henry amps are built like tanks and it is a great amplifier. You will have to pick it up or meet me within about 250 miles from my QTH - located in Eastern Nebraska. We have family in Dallas, Texas area, and I could bring down there, if the timing works. Price $1,650 OBO. Cash payment please. WTØQ

 Heathkit SB 220   
Very nice, updated Heathkit SB 220 HF Amplifier. This Amp is very well documented on multiple places on the internet so I will not go into a long discussion of the specifications/features here. Everything is working fine, it has full output and its in very good (not mint) cosmetic condition. It appears to have newer tubes and at least 2 Harbach mods; Power Supply upgrade FB 220 and the RM 220 Rectifier Metering Board. The fan is very quiet so it may have been serviced or modified recently. Currently running on 110VAC but could easily be switched to 220. With OEM Manual and an aftermarket custom dust cover as pictured. For now, PICK UP ONLY in the Denver, CO Metro Area for $1200 on a cash-N-Carry basis. I would be willing to drive (75 miles or less) to meet a buyer. Also, I will be at the Rocky Mtn. Radio Club Hamfest on Aug. 24 at the Adams Co Fairgrounds and could meet a buyer there. I have a lot of Hi-Res Pics and can provide them upon an email request. Thanks for looking
