1 year on  Time owned: more than 12 months
After 1 year - still rocking !!!
Mainly DX & Contests (SSB, CW and DATA on 1/2 pwr)no problems at all. The pwr drops a little bit after a long time running but not a big deal.
Completly satisfied.

Great amplifier in small and easy to carry package  Time owned: more than 12 months
I picked up my amplifier at the factory in Rome on my way to the IARU-R1 Conference in the fall of 2008. I hand carried it in his convenient padded bag thru Dubrovnik, Frankfurt, Madrid and finally home Caracas. No trouble on any of the 3 airlines or airports.
The amplifier has been used in activation of some of the Venezuelan rare provinces and prefix like YV8 and YV9, promoted by the Radio Club with some inexperienced and young hams as operators. Once connected the amplifier to the antennas and the exciter an IC 7000, after configure the right antennas to the bands in use and going once thru the tuner settings I confidently let the novel guys operate knowing that no damage can be done,. The linear tracked automatically the band changes, if something went wrong the many protection features worked fast.
The voltages taps on the transformer primary is much convenient, when once the line voltage was very low I changed to the 100 volts tap and the rig keeps working happily. At home I use the 220 volts tap.
I bought the amplifier with the idea to be used during our IOAT islands hopping in Venezuela and possible DXpeditions but later I am using it almost all the time at home, and the big and heavy tube amplifier with the “longest” three minutes delay has been relegated to one corner of the shack

Great amp-Loads of features  Time owned: 6 to 12 months
About one year ago, I got the wild hair to get rid of my QRO HF 2500 "rock crusher" in favor of something a little smaller with the ability to do quick changes between bands to support my mostly casual operating style. Wanting to go all solid state without totally breaking the bank, the "race" was between the THP and the SPE. I have good friends who own both and they are very satisfied with their respective decisions.

My decision was made at Dayton last year---and it was a close call---but the advanced features of the SPE won me over. I received my new amplifier in June 2010.

Steppir was very good at keeping me informed throughout the order and delivery process. They have also been excellent in responding to the two issues that I have had. They are;

1. My unit had a defective fan that produced way more noise than it should. Steppir sent me a new fan as soon as I made them aware of the problem. Easily replaced and --problem solved.

2. One of the front panel switches (Input 1/2) did not work--I only noticed it in December when I tried to use that feature for the first time. Once again, Steppir responded immediately to my quiry and after a few e mails back and forth it was determined that in fact the front panel switch was defective. Steppir put their east coast rep, Jim Streible on the case. Since I live relatively close to him, Jim actually came to my home and did the repair on the spot. Now that's service definitely above and beyond what is expected or required.

The amp itself is a dream to use. It interfaces perfectly with my 756 Pro 3 and computer. I do not miss the difference in power between 1.5KW and 1KW. At half power it is hardly working. At full power it is definitely working but not stressed. I especially appreciate the protection built into the unit to save me from those times that the wrong antenna is selected. The protection works well---every time.

In summary, this is a great little amplifier with ample power, good protection circuitry, and in the US supported well by Steppir. I have not regretted my purchase decision.

100% Up and running  Time owned: more than 12 months
After a few months back the SPE 1K is back to operating to its max efficiency. Service was outstanding and repair was completed perfect. The amp is by far one of the best on the market. Still working DX pileups with it and will continue.

great Amp - Cannot Kill it!!  Time owned: more than 12 months
Got this amp in dec. 2007 from array solutions. It was upgraded free of charge in dec of 2008 by B&B. Works great with my Ten Tec Orion 2 driving it. only takes 8 to 10 watts at the 1/2 power setting. antenna tuner "remembers" previous setting at the current frequency. If antenna changes (or I forget to switch antennas), the amplifier saves itself from problems by kicking into standby/error mode. A push of the tune button lets the auto tuner find a new setting which is then stored for further reference. Note: If the antenna itself has changed, the tuner doesn't know it! The amp follows my rig from band to band overall does a great job. Note that the antenna tuner works for an antenna SWR of up to about 3:1. Beyond that you will need to reduce drive to operate on a mis-matched antenna.
Great amp - can't kill it and that fact alone is worth paying for.

Nice amplifier, poor support  Time owned: 6 to 12 months
I bought my SPE 1K-FA from SteppIR in December, 2009. My exciter for the amplifier is a K3. The initial set up and programming of the 1K-FA was very simple and straight forward. The amp requires 25 watts or less of RF to drive it to full output. I used the amplifier for ten months without any problem to speak of. I did notice that the 1K-FA is very sensitive to temperature and will reduce power as the temperature rises. I am a CW only operator and primarily a DX'er, so not much of a problem to me. In August, 2009, I noticed that the T/R relay was sticking (not releasing to receive). I called SteppIR and was informed that the T/R relay would only switch at 15 ms. I had my K3 set to 8 ms. There is no information from SPE or SteppIR regarding that problem. I was advised to set my switching speed to 15 ms and the problem 'might go away'. Well, it did not and I was advised to ship the amplifier to SteppIR in Bellevue, Washington. The shipping cost was over $100. Even though the amp was still under warranty, I was responsible for the return shipping. SteppIR received the amplifier on September 15, 2010. I know that only because UPS notified me via email of delivery. After hearing nothing for three weeks, I called and was told SteppIR was waiting for parts from SPE. I called again a week later and was informed that SPE had still not sent any parts. I was told that they could replace the T/R switch, but they would not guarantee the problem would not occur again and that I needed an upgrade kit with firmware. I opted for the upgrade. I still have no idea when I will get the amplifier back.

The SPE 1K-FA cost me $4095, plus shipping. I would expect better support for that amount of money. I also know that SteppIR has a number of 1K-FA's waiting for repair for the same reason and for other computer related problems. It would be my advice to some one thinking about purchasing an SPE amplifier to consider other amplifiers in the same price range.

need a compact HF amp for your shack - this is it!  Time owned: more than 12 months
this little power house is a dream to own and use.

I bought this to run on HF and 6M with my Icom IC-7600. Its a perfect match!

The linear is quiet, compact, reliable and easy to drive, with a clear and helpful display.

Its has some fine features such as 2 radio ports, 4 antenna ports, CAT control/CIV port etc, plus some great touches like the super back lit LCD display with large bargraphs.

I really love this amp. Everyone who visits the shack is immediately drawn to this box!

I get some lovely reports on air with it, and I hardly ever have to do anything apart from switch it on!

I read a lot of good things about this amp- its all true!

Highly recommended!

definitely recommend  Time owned: 0 to 3 months
Compared to my previous Valve amp, this is a pleasure to use. Some of the main differences :
1. Immediate start (no warm up)
2. No tuning
3. No noisy fan
4. small footprint
5. Totally compatable with my Icom,Yaesu & TenTec i.e It follows band changes automatically, and even turns on/off simultaneously with my radio
6. Built in ATU
7. 2 x inputs
8. 4 x antenna outputs
9.Great service from RF Solutions, which is the local Australian approved dealer. Carsten , the owner has been very helpful and great customer service! 2 year warranty.
Im glad after all the research I did, that I made the choice to get the SPE. High Quality, Professional looking with an excellent informative screen display as well.
So far, so good. Il review again if i have any more updates as time goes on, as Ive only had the unit a relatively short time. So far its 5 from me!

Two years on  Time owned: more than 12 months
Had the Mark III amp for over two years, very dependable, runs 400w fully duty data on 6m without complaining and needless to say loafs along at full UK limit on any band.

Otherwise it's all be said already...

Keeper for sure.

Great Amp, Great Service  Time owned: 0 to 3 months
I received the SPE Expert last week after about a two month wait. I am still running it through its paces, but everything seems to working just fine. So far, I have gotten great reports and have broken the pile ups with the first call.

I had trouble at first hooking it up to my Kenwood TS 480HX. I sent SPE in Italy a note about it, fully expecting to wait a long time for an answer, but my questions were answered within 24 hours. Thanks, Dante.

Looking forward to many years of service from this amp.
