Super Amp  Time owned: more than 12 months
Bought used and love it. Some say Alphas are overpriced and the new owners are Horrible to deal with. I cant say I have any problems with mine or had to deal with them. As far as price, you can buy cheaper or more expensive. I think I got what I paid for. A few watts in gives a KW no problem and 65 will give you 2KW. Easy to use and quite fan. Highly recommended if you can find one.

The best I ever had!  Time owned: 3 to 6 months
I have had more amps then I can count and this Alpha 99 is the best hands down. Easy to tune, very good circuit protection and the tubes are reasonable to replace. If you can get your hands on one, get it! This is an amp you keep for ever!

Best amp I have ever owned  Time owned: more than 12 months
Bought about a year ago used and LOVE IT! Very forgiving if you make a mistake and a super quite fan. 50 watts will put it into the red (1.5KW) on any band. The L.E.Ds took a while to learn but I like them now.. Would recommend this amp to anyone looking for a SOLID rag chew amp.

Great amp  Time owned: 3 to 6 months
The Alpha 99 legal limit HF amplifier is a very solid made amplifier. Tunes very easily and I have grown to appreciate the LED meters and indicators. A quality unit and the fan is quiet yet provides good air flow.

Nice job Alpha.

Excellent Fault Protection  Time owned: more than 12 months
The Alpha 99 legal limit HF amplifier is a very solid performer.Tunes effortlessly and I have grown to appreciate its LED readouts. A quality unit,robustly built; an acceptably quiet fan and having excellent Fault Protection circuitry.

Unit acquired 'used', but looks and operates as new. Now in use for 2+ years in the tropics with several types of wire antennas from 160 to 10 meters. Line supply is 230 volts / 50 hertz single phase.

You are required some three minutes of patience for warm-up .......

Nice Amplifier, but issues  Time owned: more than 12 months
I had occasion to work with Molly a couple of years ago to get a reconditioned Alpha 99. The tech report said it was checked out and only issue was to reset the tube bias. The tech missed the noisy grinding sound when the TUNE capacitor was rotated. I diagnosed as the rubbing of grounding strap rubbing on the capacitor shaft and as best I could, I reshaped the tension in the strap and essentially removed the noise. I called RF Concepts for comments and they had heard of the problem and agreed with me that I was on the right track for a fix. As received the aged blower was a little noisy and its getting louder as time goes along. Also, they did not make any circuit modifications and I understand that the 24 volts on the amp keying relay was later reduced to 12 VDC.

Good amp, but if buying used - check main transformer brand  Time owned: more than 12 months
This is the best amp I have owned and the only one that worked perfect on every band I have used it on (I dont use 160) Mine is 9 years old and at that time was made by Cross Link. But....I recently had the main power transformer HV winding fail. Very costly item and not one you would expect to fail. Alpha (RF Concepts) tech support advised that for a period of time Cross Link used transformers made by Magnelab and had alot of problems. Apparently many were replaced on warranty but mine lasted longer. So if you are buying an older one 2nd hand you might check to see if the main transf is a Magnelab....could be a time bomb waiting to happen. Otherwise a great amp.

Simply the Best!  Time owned: more than 12 months
Had a few amp's earlier but decided I wanted a certified preown Alpha 99 from RF Concepts. Transported all the way from US to North Norway by FedEx. After a few days both boxes received safe & sound and since then been a happy Alpha owner. Amp works great, very robust and very reliable with a most helpful protection circuit.
Simply the best I owned so far!

Still going strong  Time owned: more than 12 months
It has been 7 years since I bought my Alpha 99 that I reviewed earlier here. A few years later I bought a second one used directly from Alpha as a backup unit. Great amps. I have had a couple of issues with mine over that length of time including one bad tube. Not bad for 7 years of DXing and contesting. Customer service has always been first rate. I still give the 99 a 5!
