A LOT!  Time owned: more than 12 months
I think that any OM should use this stuff! You keep your IK-FA off... did u Listen for a DX? In 5 seconds 1K-FA is ready to operate! No more tuning, no more whistles, no more warm-up!!! Think it over!

Wonderful toy!  Time owned: more than 12 months
Last summer I operated as CE0Y/I2DMI from Easter Island. Transceiver was a Kenwood TS-480 with an EXPERT 1KA amplifier and N1MM+MVARI software. I am very satisfied from both the hardware and software. I made about 2800 QSOs in RTTY only (AFSK mode) by using 550/600 watts of my Expert. I used it in HALF POWER and CONTEST mode. The PA temperature never went over 65°C at full duty. The fans were very quiet and I could operate while my wife was sleeping in the room. I had no RF problems so far with my DELL 6600 PC. The apparatus has never shown operative tiredness considering that the activity was made in RTTY only.
My main concern had to deal with the air transportation and the potential damage to the amplifier. I was granted by SPE that their packaging (double boxing) was guaranteed to any kind of shipping, across the Atlantic as well. I trusted in them and luckily the Expert went to E.I. and got back to Italy safe (abt 25.000 KM), along with the cases and the antenna.
Just to have an idea of the intense activity done in RTTY, please watch the video you can find at the bottom of my homepage:

Highly Reliable Design  Time owned: more than 12 months
I purchased my amp two years ago from SteppIR. It's been a reliable amp with no difficulties and it attains full output power on all bands. The amp interfaces nicely with my transceivers although I would like to see SPE offer an output vacuum relay and/or PIN diode option.

The amp produces quite a bit of fan noise as the PA deck temperature rises but that's something owners must live with for solid-state convenience. Output power falls off a bit too as the PA deck temperature rises.

I like the amp for its no wait time power and its solid construction solid quality, but I would not rely on it as my only amp. Tube amps still offer much more cost-effective operating headroom capability and generally, output power remains constant with PA deck temperature.

Awe-inspiring Amp!  Time owned: more than 12 months
One of my favorite items in the shack. This has changed my operating procedure for the better. I have complete confidence in the amp and it's incredibly accurate tuner. It is connected to my TS-2000 and responds immediately to my changing the bands on the radio, and tunes as soon as I press the PTT. Seeing the internal temperature of the amp on it's front display is so helpful when you are operating full power. There is a half power button on the front to dial back the power output when you don't need the full 1kw (it's actually 1.1 - 1.2kw). I feed the output through a Array Solutions Power Master SWR meter to see what is really coming out of the amp. The backlit display and the compact size of this unit make it a great, but very pricy (and heavy)addition to the shack. This amp, purchased in 2008, has helped me make contacts from San Diego to New Zealand, South Korea, European Russia, and southernmost South America, as well as all the US and Canada. It feeds a Windom Wire at 55 ft and a Steppir Small Vertical with 60 radials.

Great Solid State Amplifier  Time owned: more than 12 months
This amplifier work great!!
Really fast (two second ) and you are in frequency, without tune or turn knob for more than minute like a lot of others amplifiers. All is under control, SWR,Power,Alarm and more.Quiet and no warm added in your location when is in recive or in stby, and really compact for the size ideal for expeditions, the best one with the antenna tuner inside all included.
For my point of view is a balanced union of cost and performace for the radioham with medium budget to spend for this class of amplifier.

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.
