Great! Time Owned: more than 12 months.
Update 11/29/2024

Still in use with very very nice working power.
No issues at all so far. Working with higher SWR is still not a problem. As i said, build like a tank and looks like i keep it forever. Bought some used spare tubes for a really good price.
By the way, there will be new tubes available from China. Acom is selling them already.


---------------------------------------------------------



Hello! Today I would like to express my enthusiasm for the Acom 2000A.

I was looking for an automatic PA, which I can also operate remotely. Of course all transistor PAs came to the fore immediately.
But unfortunately I have also heard reports again and again (few), where the transistors were grilled by an overshoot.

That becomes immediately really expensive.

Furthermore (probably overdriven by modulation) I noticed transistor PAs again and again, which _not_ sounded good. Here the error is surely with the user and not with the PA itself.

Another criterion was that the output should have a good IMD3 value and be quiet in operation. I really want to have silence in the shack.

The selection meets then on the Acom 2000A.
It meets all my criteria:

- Quiet, quiet, quiet
- Remote Access and drive the PA also with Power on / off
- Massive like a Tank (i like it!!)
- more than enough reserve for 750W leagel Power in Germany
- It creates continuous operation (key down) at full power, if necessary (1500W)
- Immediate, automatic band change. One "Dit" in CW is enough.
- No problem with overshoots of any kind, a tube smiles about it.
- All possible protection functions, as built into a modern PA transistor
- Again: Quiet!

So far I got a lot of praiseworthy feedback about very clean and clear signals.
Of course, I also pay attention to how strongly the microphone gain is set.

It should be mentioned that the PA is very massively built up and offers more than enough reserves for the power supply as well.

1500W key down at the dummyload enchant the PA with a smile and no kind of strenuous work.


All in all I am VERY...really VERY satisfied with this PA and can recommend it at any time.




PS: Problems with the availability of the tubes? Not really. I could buy (matched pair) new tubes directly from a local dealer and also an offer for matched pair in local ads.

Great Durable Amp Time Owned: 3 to 6 months.
Well I received this Amp as a Gift from a Close Ham Friend who has many amps and thought this would be a great Addition to my Shack... Man was he ever Right Fully automatic and My antenna systems work flawlessly with it...... I was using a very nice Alpha 78 that I had for at least 20 yrs... I have since sold it.. As this is all the amp I think I will Ever Need... I am very happy with it, I run about 30 Watts in it for about 1200 watts which is the most I do 90% of the Time.. Of course it will do legal limit but I have found you seldom need that ...

Very Good so far! Time Owned: 0 to 3 months.
Brough the ACOM 2000A used from a HAM that lives 1 1/2 miles from this QTH, for a very reasonable price, Am very pleased with the ACOM 2000A amplifier, use it in conjunction with my Palstar HF Auto, nice combo for sure
the ACOM will do 1500+ watts no problem. This ACOM is very easy to tune, it tunes itself, but do check it every time just to make sure it does, its always been 100% correct in the tuning, am old school, just I want to make sure! Have to other ACOM amplifiers a A1000 an a A1500,
never had a problem with any ACOM amplifier over the last 15 years, an the 10 year old A2000A is working very well so far, Thank You ACOM for building Great tube Amplifiers!.....73s......WN Bryant.........kb6hrt

ok first 2 years Time Owned: more than 12 months.
In my first review i wrote many good things about the Acom 2000A, but now 9 years later, not so happy anymore, after 2 years problem started, parts failure factory called it,than 2 more years tubes dead,with all this protection, tubes schould last much longer, this amp is priced way to high, but everybody like it when it work, me to.
We schould all use it a bit longer before writing a review, those happy after many years may not use it much.I was told from the factory that tubes last normally 6-7years, mine lasted only 4years.Service from factory is very good, but it dont bring my tubes back to life.

GREAT AMPLIFIER - easy to use - full protection circuits Time Owned: 0 to 3 months.
I've had this about a month now. Previously I had an Ameritron AL-811 and an AL-80A. This beats them both hands down. This is definitely a full legal limit amplifier that will coast along all day at 1.5KW!

I bought the version without a plug at the end of the cord so I could put my own plug on it for 120VAC. You can buy one for 120VAC, they just weren't in stock. So, it cost me another $15 for a plug! It was "stupid simple" to configure the amplifier for the voltage I needed. I run a dedicated 30A breaker just for the amplifier. It will put out full power plus on 120VAC. It is not limited or crippled in any way.

It has great protection circuits. It will simply shut down if it detects improper inputs, internal currents, or whatever.

I really like the remote control head on it. The amplifier itself is pretty big. You can put it where you want it out of the way and simply use the remote control head at your operating position.

It has built-in "default' tunings for each band segment. If you're having issues with those tunings, it's not hard to add your own. It does take a little bit of time. So, I still use an external auto-tuner. Though, I'm sure if you wanted to take the time, this has the capability for something like 10 antennas and 10 user defined tunings per band segment per antenna. So, it has a lot of capability.

The instructions could be a little better. But, overall, I really like this amplifier. It is well built and very easy to operate.

Best amp I have owned Time Owned: more than 12 months.
I've has an AL-811, AL-1500, QRO 2500DX, KAP1500, and OM2000 before buying the 2000A. Of all those other amps this is hands down the easest to use and quietest. It is fully automatic tune and will loaf along at full legal all day long. Very well built and great customer support if needed.

Super Great Time Owned: 3 to 6 months.
I really like the Acom 2000. The instant band change is nice and the power is ample. 30 watts of drive gives me a little over 1.5kw.

Awesome Amplifier Time Owned: more than 12 months.
This is the first and most likely the last amplifier I will own. It is simply outstanding and a powerful workhorse. It is great looking, very quiet, and can easily push over the legal power limit so be careful when operating it!

I usually operate without it but if I am having trouble in a pileup or hitting a DX station, it is my secret weapon. Push one button to kick it in and presto - it gets me the contact :)

Best auto tune tube amp Time Owned: more than 12 months.
I currently own several Acom amps including two Acom 2000A’s. These amps are bullet proof and you need to go a long way to cause serious damage to it with all the fault protection in it. Acom Bulgaria support is great and they are fast to respond. Yes, shipping is a pain, but so is anything else with $7K price tag. I am amazed how someone can rate this amp 1/5 without explaining something that makes sense.

** Update 2021
After relocating to AR last year I replaced my older two Acom 2000's with two new Acom 2000. As before, I can only say there is no other tube amp on the market that tops these. Period.
I also installed 6 Acom 2000A's for a client in 2020 and I will continue to recommend them in the future. Whisper quiet fully automatic legal limit +++. Customer service from Acom Bulgaria is top class and Val is always prompt to respond. Get an Acom. You will not look back......

Well Overdue 20 years Update (EI2IU Original Review 2001-01-15) Time Owned: more than 12 months.
I did a review having the amp about 6 months EI2IU 2001-01-15 couldn't retrieve log in details as email address at that time long gone so no access to retrieve details for this site

20 years service unbelievable piece of equipment I have gone through some HF rigs in 20 years and thats another review and story but I still have the original Acom 2000A the best piece of radio equipment I have ever purchased

Been one of the first generation models I have had some issues but what amplifier hasn't had issues if not died completely but not the Acom still working to its full potential flawlessly 1 tube in 20 years due to a grid short so I replaced the pair

Had some connector issues and a few general maintenance bits and pieces and a couple of component upgrades over the years as one could expect however here's the punchline anytime I contacted Acom for help and direction in fault finding immediately I had a response with full support through drawings and expert help and technical support its just unbelievable

Val in Acom is a gentleman to deal with and extremely helpful and has phenomenal patience to go through every detail and step by step assistance in all fault finding tests and measurements

If you are thinking of buying an amplifier buy an Acom they are just simply the best there is in the commercial market carrying the best technical support available think about it 20 years of service with over 5 million contacts what more is there to say a company that looks after their customers provides 20 years of backup and communications with hands on technical support most manufactures would tell you get stuffed and buy a new one but not Val and the Acom team SIMPLY THE BEST ! buy one and forget about the cost its cheap how can you put a price on such a piece of engineering and support its not possible regards de EI2IU
