这么差的东西居然还卖4000多美元

看看alpha,acom算是比较贵族的。
qro,al陶瓷管功放,emtron的性价比都比om的高呀.

老外也是把钱当钱花的,性价比还是很重要。

其实赚得差不多,就差一个汇率。设备的价钱也差不多,也只差个汇率。

没有大销量,自己焊板的,看来人工够贵的,使用上应该还是不错的,什么时候有机会试试,看它干活咋样。

看他下面的电路板图好像没那么差啊。另外,那个中国制造的继电器我知道不怎么样,有人在关键时刻在这个继电器上面栽了跟头。

跟你现在手上那个比感觉如何?

陈老师你发的是老版本的了,新版的你怎么都用不坏的,它的保护太完善了,有电流保护,高压保护,ig2保护,开关机保护,见过实物再下定论最好,它的每个零件都可说是精品了,看到实物你一定有耳目一新的感觉,特别是它的空气电容太靓了,比dx-3好很多了.欢迎有时间过来测试对比.还有它的设计思路也是我们想都没想到过的............

做工没见到实物,不均论了。

突然有一石激起千层浪的感觉,起码也有两三层。但是国外功放在国内并不普及,多介绍点除大牌外的冷僻型号,对于认识功放应该有些帮助。

陈老师,迟段时间寄一台给你测试,让你看看人家的设计思路,为什么从图片上看不好看呢,因为此机比一般的功放要大约4份1,所以看不到有密密麻麻的零件,维修非常零容易,此功放连一条飞线都看不到的里面非常整洁干净,它里面那个散热风机就要1200元,那只功放管也要6-7千元,管坐也要千几元,电源部份,控制部份,机箱,加起来造价是非常高的了,所以它卖那个价并高不了多少。
    电路保护也非常到位,各个部份都有非常完善的保护,风机能随温度自动调整转速,当你关机时风机会先把功放管的温度降下来再停可以说这台功放任你怎么用都不会坏的,当你调整不正确时它就给你保护了,电源方面:一般的功放都是倍压整流,但这台机采用全波整流所以它的功率是非常强劲的,很少看到有功放采用全波整流.
    当你看到这台功放和使用过这台功放,你看别的的功放都不放在眼里了,一摆上来那个大气呀,一拆开看那个干净呀,一看那个结构那是我们怎都没想到过的,它的空气电容结构也很独特,我们中国人那个设计思路永远走不出那个圈圈,这是我自己的真实感受。

关老师,按照你这样的说明,新om2500应该是脱胎换骨了。
原来的om2500图看起来都是08年以前再再早些的产品了。

突然发现这个帖子有幸成为投石问路的妙方了。

说起电子管pa,其实按照道理是穷途末路了,但是我等爱好者乐此不疲。其实国外比较著名的产品各有特点,有的极端到ac电网输入有自动电压切换并且有稳压的功能。

说句心里话你才是我们的老师,你懂得比我多很多,以后还有很多问题要向你请教请多多指导。在此跟帖只是互相探讨,
    功放我还是比教喜欢用陶瓷管的,因为它比波离管耐用,很多大功率专业功放也是用陶瓷管的,晶体管就不用说了搞不好啪一下就没了.
  还有om这个牌子很多人对它了解并不多,因为它这个牌子的产品在全球使用的人并不多,它那个价格并不是一般人承受得起的,但用那个价格你绝对买到了让你不后悔的东西.

best of the best   time owned: 0 to 3 months
1st i want to thank tibi and all how work on ompower for there professional way on dealing with people. i had all the information about om2500hf before i buy it and tibi was very propitious, i was wandering about few electronic information before i buy it so he explains every thing for me.
ompower have on time delivering policy and i resave it on good packing.
about the amplifier, looks very good shape good materiel solid and power full, you have to tray it.
with 40w input its give you 2000+ output you can drive it more for more output.
quit, very friendly and easy to use.
aging i want to thank all people who work on this company for this art.

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.

big signal   time owned: 6 to 12 months
i have used the amplifier only under contest conditions (to5a) and it has worked flawlessly. the construction is heavy duty and i look forward to many years of usage with this amplifier. i have an alpha 99 that with the same output as the om 2500hf i had tvi. with this new amplifier i have none. very pleased!

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!

very goood   time owned: more than 12 months
hello i introduce myself fred f4fgy user of om 2500 hf since 1 year, it is very robust, and the power is well of 2500 watts exit, i find it well meillor that touts the others amp. and i will buy the new om 3500hf. greetings and good traffic

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.

excellent hf-amplifier   time owned: 3 to 6 months
this om2500 hf by om-power is the best of the best i ever used. i have nearly 40 years of experience in amateur radio – equipment and have naturally used lot of amplifiers like tl922 and ten-tec titan and some yaesu amplifiers

what really surprised and struck me with this amplifier by om-power is the rugged mechanic construction. mechanically and electrically this amplifier completely outperform my previous amplifiers and easily have much output power.
om2500 hf is very easy to tune up and with an input of 45-50watts i have 2500w output.

last but not least, with om2500 hf i have overwhelming super-reports of nice audio-reports and big signal.

the kindness and service i have had from om-power is first-class and i mean first-class that put om-power to number one and the amplifier om2500 hf to the best of best. as an addition 3 years of warranty and 1 year for the tube gu84b outperform any other amplifiers on the market. thanks tibi

i'm come from l4-b twelve years experience. tested during some contests also the alpha 91b and 87a and now after 8 months test i can say: the om power om2500hf it is a "really great" amplifier !

really heavy duty product, compliments to om power !

great amp   time owned: 0 to 3 months
10 watts in and 600 watts out was my first test!
quiet operation and real "soft on".
design is "cool".
with 600 watts out 25 minutes on "dummy load" on rtty + 7 deg change on tube airflow...

i will inform you about progres!

p.s.

dl1bbr - om is slovakia not slovenia. i wish we would produce that amplifier, but it is produced in slovakia.

outstanding amp   time owned: 3 to 6 months
outstanding processing,real 2.5.kw cont carrier out, extra large construction units like 2 transformers each for one phase, bandswitch like
a coke box (hi)...pi circuit condensers and so on,protective circuit for gu84 tube.
timeless look (a matter of opinion), fastest supply (eg: slovenia to norderney island northsea only 3,5 days)
technical designer tibi (om3rm) and its team are very reliable.
