 Henry 2K Classic amplifier  
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 100 to 150 miles from my QTH - located in Eastern Nebraska. From non-smoking home. We have some family in Dallas, Texas, and I could bring down there, if the timing works. Price $1,750 OBO. Cash payment please. Blessings to you and your family. WTØQ

 FOR SALE: Alpha 78
This Alpha 78 is as close to mint as could be. This amp was purchased from the original owner, used as backup for my daily driver 78. It has the original tubes with full output. It has very low hours. Not a mark on it anywhere. $1600.
I do not want to ship this beautiful amp but will meet someone within reasonable distance of Greenville SC. Or can bring to Dayton if someone is really interested.
Thanks,
'73

 looking for a grid meter for a al811h
Checking to see if anyone has a grid meter for a al811/al811h or if someone knows how to repair one that saw negative grid. Now the meter does not work but the voltage meter works so its not the diode d-16. I also changed the resistor that runs that meter which was open but still nothing. Thanks in advance.
