I am new to HF and have a chance to buy an amplifier.
Choices are Henry radio 3k-a or Sb-220 neither amp has been in service for about 10
years. They are both the same price (500.00) the SB-220 was in use when station was
last in service. The Henry 3K-A was purchased about 12 years ago but never went into
service at the QTH.

I know either will be a roll of the dice as to which one or both may or may not work.

So the question is which unit would be the best gamble?
Your thoughts will be helpful in me making a choice.

They are both nice amps.  The SB-220 is not nearly as Heavy Duty as the Henry.  Henry is the clear winner because that is a Military/Commercial amp built like a TANK!

No.  The 3K-A uses a pair of 3-500Zs, but uses them in a very different way from the SB-220.

It's a MUCH better amplifier in every single way I can think of.  Its only drawback is it takes up a lot of space, sits on the floor, and weighs 170 lbs.

For $500 I'd snap up the Henry so fast the seller's head would spin.  They normally sell for much more than that.

Yep after looking at the manual (thanks BAMA) I saw what it was and edited my post. I have a Henry 2K-4 and love it.

Damned if THAT question didn't get everyone hyperventilating!!  My vote: Henry!  While a floor sittin amplifier is a PIA (usually requiring a long cable from the exciter to the amp) it's a classic amplifier that you should snapped up while the gittin's good!

Roger,

   For what the Henry is worth, you could probably buy them both and take the family out to dinner.  Soooo.. Why are you still reading this?  Go, Man, Go!

A Henry 3K-A (which I have), for 500 bucks is the deal of the century, even if it didnt have tubes in it.

Buy both, they both good amps. The Henry 3KA can be upgraded to other tubes like the 8877, everything in it is heavy duty.

Sometimes you dont want noise and heat, and the SB220 makes a nice relatively quiet desktop amplifier.  Console amps make great contest amps.
If you on the air  daily the Henry would  make a great amp, if you operate casually I would go for the SB220, 1kw is enough on any band.

If it was me I would grab both of them.

The Henry can pump out RTTY and AM without worries, the SB-220 not so much.

OK i want to thank all of you for your input that helped me out a lot.

This am went to see the OM and handed him $450.00 he said well i guess so it a deal.
So now all i have to do is clear room for it and run 220v svc, and get some help moving
that pretty thing to my shack.
Guess the real hard part is learning how to tune it and get it on the air,


Again many thanks for ever ones help.

Do yourself a favor and bring her up nice and slow using a variac. Let the tubes cook for awhile with just heater voltage before apply HV. Hopefully the caps and tubes will survive the long inactive period. You are probably the envy of everyone that's familiar with the name Henry.
