COOL CALM AND POWERFUL  Time owned: more than 12 months
I always wanted an Alpha 76PA, but after putting four kids through college, I could only afford a green box.

Two years ago I bought a broken 767PA for $600. Had to put a new band switch in it, and did the 3CX800A7 conversion. Also the plate current trip circuit had a few off value components. This amplifier had been run on on a band it was specifically designed not to. Can you say "chicken band".

I am thoroughly impressed with this amplifier. 48 watts PEP of drive gives me the full 1500 watts, and the plate and grid current meters barely move at this level. This amplifier just loafs at legal limit.

The numbered skirts on the plate tune and antenna load controls allows me to change bands quickly, going back to noted settings, accurately.

The passive/toroidal, low drive mod input network is just wonderful, and has a very low swr on all bands.

This amplifier does not heat the room up like a pair of 3-500z's do, and the level of RF in the shack is much less, as seen on a field strength meter.

This Alpha amplifier, like all of their amplifiers, is a fine example of fantastic American design, and build quality.

I believe an 8410 is now on my wish list, as now I am sold on these amps!!

fantastic  Time owned: more than 12 months
Owned for over 10 years and till today with original tubes operating on all modes. I have an other new amplifier but this one is my favourite.

Fantastic Amp!  Time owned: more than 12 months
I have owned an Alpha 76 for several years now and all I can say is that it is the best legal limit amp that I have ever owned. I've owned Henry, Heath, Collins Ameritron and while they all have their own strong points, the Alpha blows them all away. It is quiet and puts out full power with little drive. It is built like the proverbial tank and it is in a relatively small (albeit heavy) package. I strongly recommend Alpha and the new company, RF Concepts, is great to deal with and provides technical support for even their older products. You just can't beat Alpha!

Like a Rock  Time owned: 0 to 3 months
I ran across a 76PA 2 holer at a yard sale I guess some CB'er had the thing for (are you sitting down???) $45.00 yes $45 bucks. and after going through it cleaning and testing componets I found some bad componets in the power supply changed them out and hooked it up to my Variac slowly brought up the voltage and no bangs Yea.
I let it burn in for 24 hours a full voltage then applied 50W drive and got around 1100W out so the tubes were good I then rasied the input power to 80W and got 1450W out man am I a Very Happy Camper ;-). In the last year I have compleatly rebuilt a SB220 and it looks like a tinker toy compaired to this ALPHA man what a Tank. I hope to use this amp for years to come.

Alpha Legacy Amp  Time owned: 0 to 3 months
I did not understand the hype about Aplha amps until I got one...... I picked up the 76PA in pristine condition for $1800 which is a lot of money for an old amp. I have not regretted it yet and I must confess - it crept in under my skin. The amp easily delivers 1400 watts with 80w drive and it is super quiet. I did the QSK mod and now it rocks on CW. Why do I like it?

a. Rock solid construction.

b. Vernier knobs for precision tuning.

c. VERY quiet.

d. Low plate and grid current at high output.

e. Still supported by Alpha.

f. Integration with new rigs is no problem.

g. It just looks good!

The only negative part is the availability of replacement tubes.......

76A Dick Byrd modified  Time owned: 6 to 12 months
I found a remarkable deal on a 76A 2 holer that was all original and running up to specs. I asked N4UQ to modernize it with low drive, WARC bands, 3cx800 tubes. The unexpected bonus was a type of tuned input! My FT-1000MP MkV now sees VSWRs of less than 1.3:1 going into the amp on all bands. Legal limit is a walk in the park for the 2 800s with drive levels of between 35 and 50 watts depending on band. Dick also rebuilt my cooling fan and it runs even quieter than before. The only thing I would do differently...I would have added the QSK and soft start mod just to complete the package. For a small "foot print" amp it delivers large scale value.

Alpha 76A  Time owned: 3 to 6 months
Didn't see a category for a 76A 2-tuber, so I'll just put it here. Bought mine 2nd hand from a retired Ham. The amps in perfect shape inside and out and I love it. I re-built a SB220 and a AL80A about a year ago and both were better than new. I had an ich to look for an alpha and found this one. I sold the SB220 and kept the AL80A for a backup. The Alpha is everything they say it is. Very nice looking and easy to tune. Mine will cruise at 1350w on just about every band. I know the 8874's are expensive and hard to find but the ones it came with are in great shape, so hopefully they will last. If not I'll send it to Dick Bryd and get the 3cx800 upgrade. I talk to Dick right after I got this one and he said if ain't broke don't fix it. Glad I had the ich. So the Alpha bug has bit me forever.

Hard to Believe This Amp is 30 Years Old!  Time owned: 0 to 3 months
I purchased an Alpha 76PA out of an SK estate at a fair price. I am running it on 110 and this beauty will put out a kilowatt with 55 watts in on SSB. Signal reports are great. This is the first amp I have owned. I'm glad I waited until I could get an Alpha. Alpha really makes amplifiers to last.
