Great amp  Time owned: 0 to 3 months
For a manually tuned, vacuum tube amplifier, This is about as modern an implementation of this century old technology as I can currently imagine. I won't repeat the good points well illustrated by others. Six meters is certainly a plus.
I do wish though that they had used vernier drives on the tune/load caps (they bind slightly) and the knobs for those controls look cheap. I find myself preferring a calibrated analog display for output tuning as opposed to the bar graph display on the amp, which is nonetheless perfectly adequate.
With all vacuum tube amplifiers these days, it's advisable to maintain a stock of spare tubes. Supply for these can only become less certain.

Simply The Best  Time owned: 3 to 6 months
Thankyou Acom for a superb product.

I can only repeat what so many others have said in there reviews about the Acom 1000.

Simple/Easy to tune 10 secs max or less.

(Att) Prev - Next function for tuning is fantastic

Over 1kw out
runs cool
Lot of protection
Looks great
Tubes still cheap
Great service.. e mailed Acom and reply same day.

I use the Icom 756pro with the Acom 1000.To key the amp i used a 7 pin din plug (pin 2 GND) (pin 3 SEND)and a standard phono plug the other end straight into the amp...The 7 pin din plugs straight into ACC(2) on the back of the 756pro.....No Hotswitching,No external Relays needed...Works fine using ACC(2)back of Icom.

The Acom 1000 is the best bit of ham radio kit i brought in ages.

Im very happy with the Amp....Its a keeper.

Fantastic!  Time owned: more than 12 months
I've used the ACOM 1000 for two years now here in Russia and have never had a problem with it! Easy to tune, quiet, over 1kW out, etc., etc. Everything fantastic, and if I ever buy another amp, it will only be an ACOM!

nicest amp ever  Time owned: 0 to 3 months
Have had them all since been a ham for 52 years.This is the best amp I've ever owned.Recently got it after hearing W4WTX on his and it sounded great.It's easy to set up and use.Getting a KW with only 45w of drive.Can't hear the fan or switching.Basically foolproof design.QSK is superb.Wish I had bought one years ago.Highly recommended.

"HOT SWITCHING"  Time owned: 0 to 3 months
I recently bought an Acom 1000. When I hooked the amp up and started to tune I got a "Hot Switching" message...I run a Yaesu FT-1000MP, this is my main rig and I use it to run my henry amp...I have a extra relay in the keying line...When I hooked the Acom 1000 up I would get "Hot Switching". After several attempts, I called Jay at Array Solutions and he advised me to take the extra relay out of the keying line.The amp then worked perfect....What was happening was the extra relay was slowing down the switching process and let rf go into the Acom before it had time to switch...This caused the "Hot Switching"
I like to talk using vox and the Acom 1000 can switch so fast that I never hear any relay switch or any thing. I can not even tell the amp is working unless I look at the watt meter...I have several amps from the Alpha, Collins,Heathkit, Commanders and Henry. I like them all, but this ACOM 1000 is so smooth and easy to tune, it is the best amp I have ever had.......

Life of HV transformer .. no more than 5 years !  Time owned: more than 12 months
I am not agree with ACOM.

The HV transformer is out and I spend 500 euros for repair.

My 25 years old TL922 is always in life. Before YAESU 2277Z, and before FL2500. No problem with, only I changed 2 time 3-500Z with TL922, 1 time 572b with Yaesu. In the same shack of ACOM 1000 now.

I know that many others people have problem with the transformer. I received other mail for that. Vince in England know also the problem.

I am not a contester and never replace the original tube. I think that there is a big problem with the production of this transformer and his fiability.

It means that a transformer need to be remplaced every 5 years !

See the mail from ACOM service :

" According to us, the product defects appear before the first year to expire.
We provide two calendar years warranty. Francis, you have used this transformer
3 and half times longer. Consequently, we think that this fault is a result from
operating conditions - increased humidity, increased ambient temperature,
increased mains voltage, any power supply over voltage, etc."

I am in France and my shack is in my house. All the conditions are good to use an amplifier. So this reply is not good.

Sorry for that because ACOM 1000 is a very good amplifier, very quiet and very nice to operate. But ACOM service is very bad. Not ready to buy the new ACOM 1500 !

Please tell me if you have also the same problem.

Best regards

Francis **F6BLP**

THE BEST 1 KW TUBE AMP. ON THE MARKET  Time owned: 0 to 3 months
After doing much research,over 2 months worth of talking to every person possible,and reading every review available, I decided on the Acom 1000 1KW single tube amp. I was convinced this was the best choice. This is my first amplifier and I did not want to make a mistake. My research showed that there are other choices that cost less. I was not interested in cold solder joints and loose parts etc. The saying you get what you pay for does sometimes apply. The Acom 1000 has a backlight display that has a wealth of information available to the operator. 14 points of info I believe. You WILL fault the amp. I was very careful and still faulted the unit. It did not call me a dummy and displayed my error. It is so easy to tune. I tune in 10 seconds. The unit is very quiet. I do not consider the 2.5 min. warm-up a negative. I consider it a positive. It takes me time just to get organized. The unit is sold by Array Solutions. The support is excellent. I have called with questions before my purchase and after my purchase and Bob has always been there with the answers. I do believe that anyone who purchases the Acom 1000 will be totally satisfied. Feel free to email me at: if more detail is wanted. so in summary...Quiet, has 6 meters, easy hook up, RF in, RF out, 1 RCA cable, forgiving, easy to tune, high quality, support, and user friendly. 73 K1YXP

On of the finest amps on the planet  Time owned: more than 12 months
I had my first Acom 1000 back in 2001. Although I had minor issues with the first amplifier, Ron from Vine UK sent me a second unit and I've been using that Acom 1000 for several years to my satisfaction.

Last year, in 2011, I was looking at another Acom 1000 but I bought a second hand Expert 1K-FA instead. Although I think it is a nice piece of engineering when using the 1K-FA for extended periods of time I could not stand the noise of the seven fans running at high speed. To much noise in the shack for me. And then there were the messages that over 80 users out of 1500 pieces sold had troubles with failing relais.

It took me not that much of time to realise that I was missing my beloved Acom amplifier so much. I sold the Expert, didn't look back and I asked Ron at Vine UK to send me a second Acom 1000. I'm so glad I did.

As for all the previous reviewers, I only can add that this is one of the most quiet amplifiers on the market. You just can't hear it working. It just sits there putting out an easy 1000 watts with no effort driving it around 55 watts from the exiter (FT-950).

I specially like the TRI (tuning aid). Tuning the amp takes me only between 5 to 10 seconds. Okay the 1K-FA had 4 outputs and no heating time, true, but the headroom of the Acom is a lot larger and the noise in the shack is gone. I can live with the 150 sec warming up time. I get myself a cold beer in the kitchen, go upstairs and enter the shack with an Acom 1000 waiting to punch out 1KW all day long while keep running cool.

I also like the LCD display. It's not that big but far large enough to provide me with all kind of info. Last but not least Acom's choice using the 4CX800 tetrode tube is great. Lot's of power, clean signal and less heat produced. Also the price of this tube is 3 times less than the competition.

Why is the Acom 1000 first choice:

- Reliable amplifier
- Very good value for money
- lot's of power
- runs cool and silent
- nice finish
- quality materials used
- lot's of headroom
- less expensive tube (GU74B)
- LCD display with handy info

Perhaps nice when new Acom 1000 arrives:

- 2 or more antenna inputs

Final word:

Buying an Acom is great but buying it at Vine UK makes it special. Ron's advice is very professional. His service is second to none. The best I've ever experienced.

In 2002 I published a review on eham (second page of this item) but this review seems to be deleted on the eham server? I can't find it no more. I hope my 2012 review reaches the public.

I recommend Acom Products and Vine UK !
