No complaints  Time owned: 0 to 3 months
ORIGINAL 2/21/2017 review:
This is from initial impressions, having received it a couple of weeks ago. Everything has been consistent with product descriptions.

I purchased from HRO and shipping was very prompt. It was well packed for shipping and arrived with no damage to boxes or content. After setup & connection to 240v I ran through the meter displays & everything was spot on for normal operation.

Connection to a TS-590S via DB-DB7DK cable works as described with the amp following band changes as they occur and getting keying signal via the cable. 1200 watt output on all bands tested with significantly less than 100 watts drive (have not fully tested 6m output as dummy load SWR does not permit full power test & MFJ-998 antenna tuner does not cover 6m).

The key loop provision allows the MFJ-998 tuner to disable amp keying during tuning & high SWR. Fan noise is noticeable but not excessive. I had some issues with the MFJ-998/TS-590S rig control not related to the ALS-1306, and the key loop made a good place to insert a conveniently placed toggle switch to disable the amp before triggering TX tune on 590S without having to use the front panel standby/operate switch.

It powers up in just a couple of seconds and then is ready for immediate use. So far, all comments for on-air operations have been positive. No issues to date. So far it has met all my expectations and I am quite happy with how it works.

UPDATE 04/14/2017:
After a couple more months use, it is still running well and meeting expectations. On a few occasions it has not caught a band change from the TS-590S while using the ARCP-590 program, but a subsequent change put things back in sync. I can generally run the transceiver at 30 watts & see over 600 watts output from the amp on the lower bands.

Excellent  Time owned: 0 to 3 months
I ordered the Als-1306 from HRO (free shipping) 5 days before the WPX Rtty contest. Placed the order on a Monday and the unit was delivered super fast the following day without having to pay extra for shipping. I owe it all to Eddie Padilla as he was the one to handle to order.

I battle tested the ALS-1306 during the contest and it did just fine. It handled 500 watts plus during the long 48 long hours Contest without a sweat. The fan seems a bit noisy on high speed but, thatís to be expected. At least it lets me know the fan is running. So If you are a not a picky person then the Als-1306 is for you. It delivers as much wattage as you antenna can bear plus then some.

I love now having a solid state amp!  Time owned: 0 to 3 months
I have had my ALS-1306 about a month now....and i love this amp! I replaced a 20+ year old AL-80A (tube type). It's just great to be able to turn it on....and go. Spot DX on the DXcluster on another band, just go there....nothing to tune...nothing to set. I have paired this amp with a Yaesu FTDX1200 and an MFJ 998 auto tuner. When i see a spot on my laptop listed on the local DXcluster.....and i click on that spot on my laptop, my radio instantly and automatically tunes to the spot frequency and mode.....and my amp instantly and automatically tracks there too. IF my antenna isn't quite resonant (though most of mine are), put the amp in standby....hit the tune button ON MY RADIO ( i have the 998 interface cable also)...and the tuner tunes in seconds....instantly if I've been on that frequency before. Amp back to operate and's just that easy.

Like others have noted, i had to learn how much drive to use on the different this amp can easily produce 1500 watts on some bands with 100 watts drive....if not a bit more (a couple of times on initial testing, my 998 shut down and said i had EXCEEDED 1500 watts!). I have a chart i made show how much watts to drive on the different bands to get 1200 watts (as exceeding 1200, might cause the output to be non linear or distorted). I'm amazed that on many 20 and 40....40-43 watts puts out 1200 watts!

I do have ONE QUESTION: Initially, i set up my amp WITHOUT the band switching i initially DID use the ALC connection on the back. With that setup, adjusting the ALC on the amp....adjusts the power output. Later, i added the band switching cable....which DOES NOT use the ALC connection on the back. Now, i don't think the ALC adjustment on the front panel of the amp seems to have any affect? So what is the function of the ALC adjustment on the front ot the are using the band switching cable and DO NOT have an ALC line attached to the back of the amp? I'm thinking, with that no longer has any function/affect?

Great amp  Time owned: more than 12 months
Why spend $7000+ for solid stare no tune amp the ALS-1306 sells for $2900 and is a terrific amp Buts out 1300 watts and is all automatic I have had no proplems at all with this amp

Good amp that delivers what it claims  Time owned: 0 to 3 months
This is my fourth solid state amp. I have a Ten Tec Hercules as well. I have had the ALS 600S and the Yaesu VL-1000 before. The 1306 delivers 1200 watts without breaking a sweat - care must be taken as it will easily go beyond the 1200w level. The fans are much more quiet than those in the VL-1000.

The only gripe I have is the loud clanking TX relay- for an amp at this price a quiet QSK capable TX switching should have been standard.

Apart from the loud relay the amp is a solid performer.

Great little Amp  Time owned: 6 to 12 months
I've had this amp in service for about 7 months now and love it. It does all it's reported to and very easy to set up quick. I've got mine paired with a Yaesu FT2000D with the optional data cable and a 6 band Hex Beam. Having the data cable makes operating so easy since it's just a point and click from most supporting logging programs and it takes you right there. Whats really nice is the 6 bands on the hex beam are resonate so no tuning is required. It's very easy to switch back and forth from standby to operate by simply reducing power from you radio and nothing required at the amp. I recommend that if possible to run it from a dedicated 240amp circuit as it comes from the factory because it does pull the amps when close to full power out put. I've run it good and it never breaks a sweat. The power supply and amp have excellent cooling fans that do a great job with minimal noise in my opinion.If you have the opportunity to buy this amplifier do so. Once you put it in service you'll never want to return to tube amps (my SB1000 is pretty lonely now) hihi. In closing if it were ever to develop problems i'd never hesitate to repair or replace it. 73 K4SAW

Excellent / Convenient  Time owned: 3 to 6 months
I got a used (2 mo) 1306 from a Ham who loved his Drake L4B which was damaged and then fixed, for $1K below list ! I use it with an Apache Labs Anan 100d and a Palstar HF-AUTO. I wrote software to control the HF-AUTO, the ALS-1306, and my Ameritron RCS-8/RCS-10 remote antenna switches and now I have a completely automated station, just point and click on the frequency and everything else automatically follows.
I used the 1306 in the 2016 ARRL DX contest, ALL GOOD!

Worked for one minute  Time owned: 0 to 3 months
Looked ok - nothing rattled - put out 1200 watts on 10m for 15 seconds, 1200 watts on 15m for 10 seconds, then switched to 20m - while slowly increasing the drive, at 600 watts out it faulted.
Would not work after that.

Factory very nice when I called about service. Sent it back in less than 24 hours after receipt.
After a week, though I'd check the status. Was told four to six weeks before looking at it.

So, duty cycle of less than one minute on, 6 plus weeks off?????

Don't make the same mistake.

So far, so good  Time owned: 0 to 3 months
I just got this amp on the air this week. I admit that I bought it with some concern about quality due to the reputation of the parent company, but this product seemed to be perfect for what I needed (HF remote operation). I got this on the air pretty quickly with my spare IC746PRO driving it.
The amp easily does everything it promises. Drive it hard enough and it does close to 1500 watts output. Limiting it to a KW seems prudent though. The ALC worked perfectly with the Icom radio.
Icom uses an analog voltage output from the ACC2 connector for band data operation. This is not an ideal way of doing things, but the 1306 decoded the bands perfectly with the accessory cable (not included). There is some confusion when operating in the remote position since several bands are shared (e.g., 10/12 etc.). When selecting 12m on the ICOM, the 1306 switches to 10m. Similar issue with 20m/17m. But in all cases the 1306 switches the correct output filters for the selected band even though it does not display it properly. This is partly the fault of the Icom analog band data output so I don't derate this amplifier because of it.
But after one brief QSO, the band data remote stopped working and was "stuck" on 20m. AHA! There's that quality problem I feared. But it turned out that the IC746PRO stopped outputting the correct band voltages. I tore apart the radio and traced the problem all the way back to the main processor. Fortunately, a factory radio processor reset corrected the problem. I admittedly didn't have a good common ground for this first test so I fixed that and haven't had an issue since.
While it may come out in second place in the cabinetry department compared to the Japanese products, it still looks good and it does what it says it will do. The manual could be improved a bit. For example, it says that the power supply can be "easily switched to 120v" operation but does not give any instructions on how to do that. But that's not recommended anyway. They've included most, but not all of the schematics ... even if they are pretty hard to read.
I had major power supply problems with the more expensive Yaesu equivalent of this amplifier. The 1306 does not need to use an auto-transformer to convert the US power standard of 240v to the Japan standard of 220v. The supply is rated up to 260v input. My power line is very slightly above the US nominal: 244v. This voltage would possibly damage the Yaesu.
Yes, the fans are a bit noisy and the relays are loud, but my only "complaint" so far is that I have to buy a space heater for the shack now that I don't have filaments to warm me up any more.
The ALS-1306 is pretty much plug and play and does everything it says it does. Now I just hope it keeps on playing.

Great AMP  Time owned: 6 to 12 months
This is my 2nd report on the ALS-1306.
I have use this amp for about 7 months now and
I can find nothing wrong with the operation.
Work 3 contest and a lot of DXing. On SSB it seems that 800 watts breaks in to pile up with no problem. On CW I use about 200 to 400 when there is a pile up or bad conditions and it seems to do the job.
On RTTY I have use up to 400 watts and have no problem. I have had no reason to go any higher in wattage with the AMP. For a solid state AMP I give it a 100 per cent. And again TNX to Mike at AMERITRON he has help 1000%
