Cheap @ HI price Time Owned: more than 12 months.
After 18 months of use I can write nothing that "it not worth the money!"

deficiencies:
-NO vacuum relay (on qsk cw it seems that you are a Tip Tap dancer)

-Very noisy fan (I think that a 2 step fan is a MUST)

-NO 6:1 ratio knob

-SWR protection does not works well (I can tx with 5 of swr on 160m)

-2 Phases line is not easy for everyone

-HT primary voltage is not selectable, you CAN’T select 220 to 230 or 240v

-24/28 & 18/21 band switch, not a good thing on his price class!

-HT meter works at end of scale …3kv

never again

Dream Machine Time Owned: 0 to 3 months.
this amp opens the world. I used an Ameritron 811H before, which was a nice machine, but was overloaded at maximum legal power.
The OM2500HF has so much reserves on all bands and makes a crystal clear and powerful signal.
With this perfect amp I am ready for the upcoming solar cycle.
Thanks to Tibi for the good support and the very fast delivery during the ham fest.

Dx machine Time Owned: more than 12 months.
These days I was thinking of a word to try to define the quality of om 2500, but after a long time I realized that I have no capacity to try to put into words the quality and technology involved in the OM 2500 the only thing I can do is thank Tibi.now I'll dream a little louder and I leave for OM 3500.And remember this amplifier power over 2000w, so be prepared cable and antenna to support this power.sorry for the English and I hope they understand the text.

3K badboy amp Time Owned: more than 12 months.
Here in the high arctic, you can realy feel the loss in the auroa, to handled the loss OM2500 is good choise. It put out 3K on PL-259 output connector. There have not been any problem, only when I forgot to switch band or overload it with 100w. The safety put it in standby for 2sec, then it is ready again. Next step will be 3500 automatic.

best amp I ever had Time Owned: more than 12 months.
We use an OM-2500 amp for some years now @ DR4A. The amp runs flawlessly without any problem or interuption. One time I produced a problem inadvertently and OM Tibi OM3RM did reply very fast and straightforward; great service at all ...

Connected to a stable power grid it will put out some more than 3kW even on the higher bands. 2.000-2.500W are easy to achieve even in RTTY. On a fieldday the power connection with two independent cables allows operation on two smaller power generators. The military power tube GU-84b allows operation at 500 W out without cooling for 30 minutes; giving some additional safety. I like that.

A sure to please product with a great service leaves no suggestion for improvement.

Amazing quality Time Owned: 0 to 3 months.
I had the chance to operate this amp during the WAE SSB contest when we were active as 4U1VIC. 15 Watts input gave a smoth Kilowatt output and there were absolutely no problems during the rough contest operation. This amplifier can be recommended to those who can afford to buy the best.

Brilliant Time Owned: 0 to 3 months.
I am owner of om2500hf for one month. Serial number 757. I bought diretcly from Slovakia with very good and professional service by om3rm, Mister Tibi.
I am useing amplifier in the building in the center of city, and with full output no any TVI! Wow! For conection with ft2000 I spent only 2 min. ( I am medical doctor with poor tehnician knowlege). Amplifier work very quiet. Easy to tune up. SWR meter work even when amplifier is switch off as a external SWR meter for rig. Good protective sistem.
Very simply to use.
Now I have a big signal on the air. When you buy om2500hf you have lucky price to became a Big Gun!!!

Again, compliments for om3rm, and he is great constructor and good professional. Clear and fast comunication, and keep word in deal!

Excellent HF-Amplifier Time Owned: more than 12 months.
At the OM0C Contest Crew we are using these amplifiers for some years, mostly for contests and DXpeditions (3B8/OM0C, IB0/OM0C, C52C & C50C) and there we had a chance to operate OM-2500 for some weeks under very hard weather conditions when temps inside rised more than 40 degrees Celsius for 24 hrs a day. The amplifiers alive even very hard handling of different airports staff which confirming the very good and sturdy construction. Most of us are also guest members of OM5M and OM7M contest stations and we have the same favourite, OM-POWER.

I'm not only contester, but technician engineer too. From my technical point of view, this is the best amplifier I've seen. Robust construction, easy to operate, the tuning is one of the easiest I have ever used. Also the protective systems is working fast. The blower on my amp is quiet. And with 50W drive I have 2500W output! I simply love this amp!

If you want to have big signals on your DXpedition, this is the right choice for you!!!

Thanks to Tibi OM3RM & the OM-POWER team for this excellent product. Well done boys!

I'am happy owner of OM2500HF Time Owned: 3 to 6 months.
I`m a very happy owner of an OM2500 HF amplifier. Just my station is in balanced with RX and TX side.

This is a well engineered, well constructed and well built PA. The tube, GU84b is a new generation tetrode, built for the Russian army. The robust tube and the same robust power supply with 2pcs of toroid transformers, gives 4.5KVA continous input power. The RF part is clear and beautifuly designed. The protection system has made the PA “bullet proof”.

I use the IP dip and LOAD for maximum output tuning methode. This is a fast and perfect way. My own tuning chart gives me opportunity to change band w.o. driving signal. The large metering is very good because I can see all the important parameters and also see that the amplifier is ON or OFF. :-))

The output signal is clear and narrow. During the contest some of my neighbours came to 300 Hz to me and made me some QRMs. When I asked them to QSY a bit they answered: “SRI, I didn`t hear you - 300 Hz away”. So this is a very good and one of the best price/value PA.

Please read again my first sentence.

Thanks to OM3RM, Tibor and his team, from Slovakia for their nice product.
