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!

Alpha 99,...a Tried and True Amplifier  Time owned: 3 to 6 months
Considering the many HF amplifiers out there, I decided to step up to a full, legal limit amp. A natural choice for me was the RF Concepts Company-Alpha given their solid products, excellent reputation, service/repair, and superb customer relations/support (Molly).
The Alpha 99 has been around for a while now and seems to continually be a highly, sought after amplifier on the used market,... holding its value very well.
Compared to the 91B (Bulgarian-made), the 99 (Made in USA) has the Hypersil Peter Dahl transformer and some other differing parts. Both 91B and 99 use the same rugged and dependable Russian tubes, but there is just something about the stamp on the back that reads,...'Longmont, CO'.
I researched this amplifier for a long time and made several contacts with Molly about possibly purchasing a newer 8410. I decided to go with a used 99 instead due to its great reputation and storied reliability. The 8410 in itself, was designed off of the 99's chassis and platform.
I strongly recommend this amplifier if you are looking for legal limit, loafs all day long @ 1.5kW with 40-50W exciter drive.
Considered a 'Legacy' amp by RF Concepts-Alpha, parts seem readily available if there is a future problem. The blower in mine started to rattle so I ordered a new one. Installation was a snap and now whisper quiet.
I am looking forward to many years of service with this truly, wonderful amplifier.

Ótimo Amplificador  Time owned: 0 to 3 months
Eu comprei o meu primeiro Alpha 99 em Agosto de 2012, ele é simplismente o melhor linear que ja tive, gostei tanto que acabei comprando um segundo, so que este é o Alpha 99CS. Tenho os 02 em minha estação (Veja QRZ.
A sintonia muito facio e trabalha sem ruido, muito silensioso.
Parabéns a Alpha!! Os amplificadores sao realmente os melhores, "QUE VENHA O 8410 MINHA PROXIMA COMPRA"

Excellent 99!  Time owned: 0 to 3 months
I am a very happy new owner of a “Legacy” 99! Molly helped me buy a “Certified Preowned" 99 with warranty and it looks almost like new. You can tune “by the numbers” and it loafs along at the legal limit. It is very quiet, even with the auxiliary fan on! I should have bought an Alpha many years ago! I am looking forward to many years of enjoyment with my 99! Call Molly! Get an Alpha! You will be happy you did!

Outstanding!  Time owned: more than 12 months
I've had my Alpha 99 for quite a few years now. I love it! Have never had a problem with it--except for those I accidently induce. Then, the protection circuit kicks in and saves me and the amp. The Alpha has helped me to work a lot of DX. I keep a tuning chart for each antenna and bands: Tune and Load settings. I can switch bands and be ready to go in seconds.

It does everything I expect from it!  Time owned: more than 12 months
I own Alpha 99 for a few years now. What a geat amp. Very solid design. Reltively light, very powerful and most important, very reliable. If I was to choose another amp in the future, Alpha would be at the top of the list. Thanks for a great product.

Final Comments  Time owned: more than 12 months
As I get ready to send my Alpha 99 back to the factory as a trade-in on the Alpha 9500, I must say that after 5-6 years of ownership I could not have asked for more out of an amplifier. It never once failed to perform at peak output, and the 99 forgave my errors of trying to tune up on the one band with the amp on another, super fast default. Why am I getting another amp if I like this one so much? Just want to try something new and the trade-in price I got was VERY GOOD. Looking forward to another great amp--you get what you pay for with Alpha.

Ask me  Time owned: 6 to 12 months
Have had this amp for a year now (bought it directly from RF Concepts) and am very, very happy with it. (It has serial number 499, it's the second to last ever made from what I understand.)

The only slight "issue" I can think of is that it draws a lot of current from the AC line. When the amp is keyed, the AC supply line voltage drops from 217V to 207V. But this is the house wiring's fault rather than the amp's. RF Concepts recommended me to try wiring the amp for 200V instead of 220V in order to achieve the nominal 1500W output, which I haven't tried yet. I now get 1200-1300W which I think suffices.
All in all, I would not hesitate to recommend you to buy this amp if you can find one. It feels really robust and operates quietly.

Awesome and Reliable  Time owned: more than 12 months
I have owned my Alpha 99 since 2004 and it has been a dependable and easy to tune-up Amp. I typically only drive it with 35 watts for 1500 watts output. When I occasionally make a mistake such not properly changing the band switch, the fault protection kicks in to protect the GU-74Bs. Over the years, I have been extremely pleased with the world class customer service provided by Molly and Glenn. My next Amp will be an Alpha 8410 because I find Alpha Amps starting with my Alpha 76A purchased in 1978 to be the best HF amps available.
