3K Classic X MK II (3CX1200A7) Time Owned: unknown months.
One pharase that comes to mind in describing this amplifier is: "Industrial Strength"! Everything about this amp is geared towards durability. The
power supply is beyond heavy duty ( the plate transformer alone weighs more than many legal limit tabletop models ). The tube employed
( Eimac's 3CX1200A7 ) with it's 50 watt grid dissipation is indestuctable under normal usage, adding to the amplifier's overall toughness. If there are any drawbacks to be mentioned, it is that the amp also comes with an "industrial strength" blower which really lets you know the amp is there when running. Also, when changing bands the roller inductor "tune" control can take quite a few turns. Henry has remedied this by offering a matching crank style tuning knob which makes switching bands much easier ( perhaps Henry will include this knob on future amps??? ). In any event, the positives way outweigh the negatives. This is in my opinion the best, toughest manual tune amplifier on the market today. If you want a trouble free amplifier that your great-grandkids will be able to use, then this is the amp for you.

Henry 3K Classic-X w/8877 Time Owned: unknown months.
There is simply nothing like a Henry. Everything is heavy duty. I bought mine from an estate sale and after a few modern mods such as an electronic 3 minute timer it has worked flawlessly. With 4200 volts on the plate, it does 1500 out with 40 watts in on all bands including 10 meters. With 50 to 55 watts drive it does 2000 out. It has a tuned input for each band and a nifty test point on the back of the amp to check the filament voltage. The power supply is heavy and well regulated. It makes most table top amps look like toys. Yes, Henrys are big, but if you take a peek inside you'll see why.
