Sorry, Dan, I've looked at and repaired the very latest Henry amps. My
comments stand (you might read them again).
As I said, the 4K-Ultra is built better than all the current Henry amps
with the cheap roller inductor and "off shore knock-off" fixed caps
...that's why I'vekept it. Although like all the other 4K-Ultra owners I
know, I've had to modify the blower system to make it really work
right.
As for the roller being bought by other manufacturers...water seeks its
own level...bet Continental, Harris or Collins aren't customers for them.
And of course that doesn't say much anyway, MFJ uses roller inductors.
As for selling you my 4K-Ultra, it wasn't too many weeks ago that you
were advertising to buy one here on the Internet...guess you agree that
its a better amp thatn you 3K Classic X MKII (which from the pictures on
your web site looks like it could use a bit of rehab as well).

I can personally show you a HENRY that doesn't vibrate, MY 3K Classic X

Apart from the 4K Ultra, I can see that you should know better about weak
power supplies........
BTW, maybe you'd like to sell me that 4K Ultra nice and cheap as it's
such a junker, eh?

<bold>- Among others, amps by Harris, Henry (4K-Ultra) Alpha (87A & 77SX)
Drake (L-4-B), and a number of homebrew amps (4CX1500B, 8877, etc.)... as

>Fact: The transformers used are very reliable, we wouldn't continue to
use
>them if they were junk!
<bold>FACT: Henry has persisted in using unreliable components in their
amps for years. Ask Pete Dahl how many transformers he sold to replace
the early Triad and current ECA transformers Henry put in their amps.
Even the Henry 8K-s have weak power supplies...all the guys around here
who bought the vaunted 8K-Ultras had to buy replacement transformers....
And don't overlook the history of failures Henry's had with the cheap
Dayton blowers they use (e.g., in the 4K-Ultra).

and

>make the parts like HENRY does!
<bold>FACT: You and I both know Henry went to this make shift scheme as a
cost reduction scheme, not because it was a better way to go. And those
roller inductors are a joke (go look at the Johnson and Multronics
inductors if you want to see decent quality; Henry used to use them
before the cost cutting took over.
By the way, roller inductors are notoriously unreliable in r.f. tank
circuits due to arcing and pitting. RCA used to use this fact as a major
weapon in its sales campaigns against Gates (RCA used tapped inductors;
Gates used roller inductors in their tank circuits; Gates transmitters
were famous for "zorched" tank circuits).
</bold>>Sheet metal? You must be looking at something else. We use
aluminum.
<bold>FACT: Last time I checked, aluminum was metal. And since its used
by Henry in sheets to make cabinets and chassis, its called "sheet metal"
(see you learned something new, Dan). At any rate, you dodged the issue.
Henry's cabinets <underline>never </underline>fit properly. I defy you to
show me a Henry amp cabinet with sheet metal fits properly with its screw
holes (Henry is famous for making the screw holes on their cabinets line
up by reaming out the holes; as a result, their amps always look like
they were made by "shoemakers")
</bold>FACT: And while you're at it, show me a Henry amp cabinet that
doesn't vibrate like the devil. Guess the solution is to buy a 3 or
8K-Ultra and put it another room. That's a great selling point.... I
don't use my 4K-Ultra very much for because I can't stand the noise it
makes. If you want quiet, don't buy a Henry. Or at least, build an
addition to the shack to isolate your Henry in (unless you don't mind
operating in an environment that sounds like you're on the flight deck of
an aircraft carrier.
Dan, the point of all this is to say that Henry amps are built for a
price and are not the most rugged, reliable amps built. At least not in
my 30+ years of working on them.
