All of the above amplifiers are fully tested and we provide and
install the proper 240v plug on the power cord at no additional cost. We
also re-pack the amplifier to assure safe delivery to you and then send it
with full value insured UPS Ground shipping for free!

Other Frequently Asked Questions:
*** TUBES ***
Fact: The rumor of tubes not being available for these amplifiers is false.
We have them in stock. We have a good and continuing supply of "new old stock" (NOS)
matched pairs, at very reasonable prices. Currently a matched
set of GU74B (4cx800) is $600 for the pair.
Array Solutions understands the GU74B (4CX800) situation as follows:
- Svetlana still makes these tubes - but not on a regular basis.
- New tubes are very expensive - > $1k per tube.
- The date code on these tubes makes no difference.
- If it is "new old stock" it's still new.
- If you think about it, any tube becomes "new old stock".
- Every tube supplied in an Acom amplifier is fully tested.
- Every tube sold in an amplifier has a full new tube warranty -
regardless of date code.
- To get a decent per-tube price, Acom purchased a warehouse full of
- The Russian military still uses these tubes in their communication
Are these amplifiers noisy? These are probably the quietest
amplifiers made. The 1000 and 2000A cannot be heard even when 1 meter
away. And QSK is whisper quiet and accurate with a dedicated QSK
process on board.
The need for an external fan for full output
with normal RTTY, SSB, CW, or other digital modes is not necessary.
We have the fans in stock, but it is thermally controlled
and probably will not come on even in a RTTY contest. The internal
blower is quite adequate to keep these tubes cool, and each tube is
monitored for its operating temperature. Acom does not recommend the
external fan for normal operation.
FCC and 12/10 meters. The FCC did away
with the 10m modification for RF amplifiers years ago, each one of our amps
is factory set up to operate on 12/10m.
Fully Automatic at full power output every band
switch every time. The ACOM 2000A is always
ready to deliver full power with one of the fastest tuning and memory
algorithms on the market.
Front Panel Control.
The ACOM 1000 has a unique front panel LCD display for control and
tuning, the ACOM 2000A is the only amplifier that has a remote control
panel, which can sit right beside your keyboard for full visual observation
of many of the amplifiers' operating parameters: the forward power, reverse power, VSWR, and alarms. An incredible amount of information is at your
fingertips. The protection circuit alarms are also located on this
handy remote control. Put the amp out of the way, there is no reason why you
need to touch it. The Remote control also turns the amp on and off, as
well as puts it into Standby.
Configuration of Mains AC Power taps.
We pre-set up your AC Mains taps. Once set to 240V AC you
don't ever need to change them unless you want to take it on a DX-pedition
and then you will remove the transformer for transportation. The
taps are set with removable solid plates that screw into place. No soldering
at all. The mains voltage is constantly monitored by the
amplifier as well as HV, Screen voltage, and filament voltage.
If any voltage falls out of the operating parameters, the amp will warn you
and shut itself down if necessary.
QC (Bird type) RF Input and Output Connectors.
Nope, Acom doesn't have them. Instead they
use heavy duty SO239 connectors which are soldered to the RF connections.
Factory US Service and Support is
done by Array Solutions right here in our RF Lab. We are certified by the
ACOM factory to perform all repairs to the component level. The
reliability of the ACOM amplifiers are well known and especially the ACOM
2000A which has been proven since it was introduced in 1998.
High Historical Trade In Value.
Any check of the well known classified ad websites will prove
that the ACOM 2000A and 1000 amplifiers have a historically high value.
Indeed a recent sale of a 12 year old ACOM 2000A went for USD $5,000.
What is the Warranty Policy?
Solid product backed by a solid warranty.
Standard Two-Year Return-to-Factory (RTF)
ACOM stands behind all its products with a two-year warranty. If your ACOM
product fails at any time during the coverage period, ACOM will repair or
replace the unit. Your only responsibility is prepaid shipping back to Array
service center. Warranty coverage for tubes is one year.

Who will repair the amplifier if I have a problem?
Array Solutions is an official ACOM repair
center. These amplifiers are built to high quality standards and will last a
lifetime. But occasionally, there may be a problem. Many times we can
resolve the problem working with you on the phone, and even sending you a
part to replace if you're capable of doing the work yourself.
Can I have a set of Schematics for my amplifier? Yes, we can
prepare you a CD with schematics, and hundreds of pictures and technical
Is the ACOM 2000A truly a full power auto tune amplifier, or do I
have to tweak it to achieve full power? No Tweaking ever.
The tuning algorithm is fast and accurate. It never needs "touching up."

especially in the power supply PC board area).
