Excellent Older Amp  Time owned: more than 12 months
I owned a new Alpha 76CA for six years, and it was a fine piece of equipment. My use was primarily contesting, and it saw hard use in many multi-single operations.

It made two trips for contest operations on Anguilla in VP2E operations in 1981 and 1982, where generator power provided a less-than-friendly power environment. Kept on ticking through the contests.

It was a sad day when I sold the '76CA to take a once-in-a-lifetime opportunity to buy more land around my house, but the decision was a good one.

I'm now using a pair of Alpha 91B amplifiers, and they are better suited to the the current power limit rules (1600 W dissipation vs 1200 W for the 76CA). The 4CX800A tubes are *much* cheaper than finding a trio of 8874 today, and the newer amps work less hard to get to the legal limit.

Given the bargains available on some of these legacy amps, the Alpha 76CA is a good choice for many applications.

A Thoroughbred  Time owned: more than 12 months
The 76CA has the epoxy-sealed Hypersil transformer, which offers higher voltage, less heat, and lighter weight. It is the one to buy, if you're looking for an earlier Alpha amp.

The "CA" also has 3 8874s, which if not repeatedly over-driven (abused), will provide the legal limit output for years. The nice thing about an Alpha, is that it genuinely loafs at 1500 watts pep! If you turn up the drive to 100w, you'll need a wattmeter that can read above 2kw (into a dummy load, of course!). And all this with very little fan noise, and not a lot of heat coming out the vent holes in the top of the cabinet!

One peek inside, and one hour chasing DX on your favorite band, and you'll no longer feel bad about having paid so much to get one of these!

New Front Panel for Alpha 76A's  Time owned: 6 to 12 months
I just received a new front panel for the ALPHA 76A's.. Wow it really makes a difference in the shack. No problem putting it on. It took only 5 minutes and was accomplished without unhooking anything....

Alpha now has these front panels in stock. Call them to order. P/N is MSX-X001

Great Service  Time owned: 0 to 3 months
I owned an Alpha 76PA back in NJ for 5 years with no complaints or problems. Sold all my Ham gear when I moved to Florida in 1990. Since the "bug" just hit me again (contesting) after a 12 year laps, I finally found a Aplha 76CA here in Florida to be the workhorse for building my new "shack". Contacted the Alpha group via EMAIL to see what support was available for the Legacy Amplifier. Sent the email to their staff( and was very surprised to receive an email response within 30 minutes, with a complete description of what Alpha has supporting the 76CA ... wow Alpha is still king!!

Technical Support can be found at and also confirmed that a new front panel for an Alpha 76A, 76PA or 76CA was still available... part number is MSX-X001.

My Alpha 76CA still puts out 1500+ and is simple to operated. Highly recommended as a desktop 160-10 amp.
