GREAT  Time owned: more than 12 months
I have several amps, My AL-1200 is by-far the #1.
It has a 30 second start time and gives full power. Not ever a problem. Works full duty. A little sensitive on 12 meters. I have operated mine for over 5 years now and would buy it again.

WHAT A TANK!!!  Time owned: 0 to 3 months
I am experienced with legal limit amps. Commander, Alpha and others. All I can say is WOW. I bought this TANK used only 20 minutes on the tube. the amp was purchased originally from a ham that is a silent key. His brother got it. No use. The boys were only mid 40's and i turn 46 this year. Paid 1900.00 for it went to outside of Detroit and paid for it brought it home. Shazam!!! A-4s, A-3WS, HF-2, and others they all love it. EASY TO TUNE FORGIVING. Find one. Buy it. I have heard they sell medical pulls in NE Ohio 3CX1200A7. If any body has a line on this, e-mail me.

I love this amp  Time owned: 0 to 3 months
Have had my AL-1200 for only four days. It is serial no. 0277 and I bought it from a eham classified from a fine Ham in TN. It came unmodified and I inspected all workmanship before installing XFMR and tube/chimney. I was positively impressed by the workmanship involved. The power output is there plus, even for such an older unit (all original so far as I was told and can see). It is easy to tune and forgiving of operator headspace (if anyone can blow out a tube I can). This is my first full legal limit amp and I expect it to be mine for life. The blower, as described by many, is noticable - yes it is. I chase DX and usually the hot DX are pretty light. My ears are 57 years old now but I find it not an additional problem copying the light signals with this amp setting beside my rig, right there with me. Tuning is dependably repeatable. I paid a certain fair price for this amp just a few days ago and would NOT take an additional $500 profit for it. This is my keeper and I am so very happy to be able to have her. I love this amp.

Perfect 1.5 KW amp!  Time owned: more than 12 months
My AL-1200 is going on 10 years of near flawless performance.

My only failure was the surge suppressor relay in the HV primary circuit. Within a week I had a new relay and replacement resistor (design change) that went in easily.

If I had to purchase an amp today, I would not hesitate buying an AL-1200.

Beyond Excellent  Time owned: more than 12 months
I wanted you to know the AL-1200-XQ is working flawlessly and the new 2.5KW Pin Diode QSK-5 PC internal PC is AWESOME ! It is seamless and silent, you can not detect any attenuation on or off and it is as smooth as if you were using the K C keyer, Perfect With the Icom. The new QSK-5 switch is far better than the old pin-5 switch as far as attenuation,swr change,loading and logic. the 12v jack on the back now has a lable called Handshake used for yaesu and Ten I'm very happy with it.Love the instant on of the 3CX1200A7 truly a tuff tube,mine is 20 years old and puts out +900 watts with 30 watts in,and goes way beyond our needs. Need Help?? talk to MIKE ENNIS @Ameritron he is great to work with....!

Good Value for High-Power  Time owned: 6 to 12 months
My AL-1200 was rescued from CB service and is about 5 yrs old. It proabably wasn't used for ragchews or contesting. The HV cap and diode boards are shared with 2 other full-power amps and the caps are pushed beyond the max rating. Two of my 'lytics vented violently leaving a mess to clean up and $120 for new ones. When installing the xfmr and tube, do inspect and tighten everything because MFJ is notorious for bad solder and loose screws. The AL-1200 is NOT an Alpha but I didn't pay for one either. It's a good value for the bucks.

Well Built Amplifier  Time owned: more than 12 months
I've owned two of these in the past and just bought another one used. It's a fairly early model but it works great. This one still has the original tube and only takes 75 watts to produce legal limit. 100 watts makes about 1950 watts out. Although not as much output as my 800H it is built better on the inside with better components. Would probably take alot more abuse than the 800H as well. I'm very well pleased with it.

Pretty Good Service  Time owned: more than 12 months
I have owned the AL-1200 for about 2 years. In that time, I have had no problems with the amp, even when on the wrong antenna. I have a PL-259 that this amp burnt up without damage to the amp. I run legal limit for hours during contests and about 1K during RTTY contests. I don't doubt the ability of the amp to run legal limit with RTTY, but want to take it easy on the radio during that time.

I highly recommend this amp as the tuning is very smooth and very tolerant of operator error.

6 YRS & STILL GREAT  Time owned: more than 12 months
I have had this amp for over 6 years - bought it new.
IT JUST KEEPS ON PUMPING OUT 1500W ON ALL BANDS despite my many senior momements....

I have owned many amplifiers but this one is the best - and it is a basic amp that any OT OP will be able to maintain....

Smooth loading and MOST Rugged

Excellent value  Time owned: 6 to 12 months
I got a good deal on a used AL-1200 made in 1987 that needed some refurbishment due to prior operator mis-use, not design deficiencies. It now puts out more than 1500 watts CW with the original tube! The 3CX1200A7 is a very rugged tube.
I replaced the arc-damaged plate tuning cap (from high SWR) and replaced an arc-damaged 120 VAC SPST step start relay with a $10 double-pole version, both poles tied in parallel, and the step start resistor with a 20-Ohm unit, as used in the newer units. I replaced the meter lights (which had burned out) with a light-bar I made from 1/2-inch plexiglas bar stock, and 6 super bright white LED's, 3 above each meter(and appropriate series dropping resistors). The LED lighted meters look great. Stripping and repainting the cover made the amp look like new. When I replaced the bias zeners (one had been damaged) I improved their heat sinking to the chassis with an aluminum strip with smaller thru holes, and thermal grease. I adjusted the position of the 40-meter coil to reduce coupling into the cover, per factory suggestion. I made 0-100 scales for the TUNE and LOAD caps, that I laser printed. This makes logging settings much easier. Factory technical support was excellent, and Ameritron replacement parts cost was very fair (zeners and new plate tuning cap). I have several HF linears, this one is a keeper!
