Wish they still made these !!  Time owned: 6 to 12 months
KC5TJT has one less 77SX now, because I bought one of his. It is a great piece of equipment; easy to tune and built to last. I wish Alpha still produced them, but even with a few years on them they are still top-notch. I also have an Alpha 99 that I purchased new, and it works fine, but I like the 77SX better. Maybe its because of the "old-fashioned" meters where you can actually tell what you are doing, instead of the bar graphs. Either way, Alpha is still top quality....if you want a top-of-the-line amplifier, get a 77SX.

Sweet!  Time owned: 0 to 3 months
The Alpha 77Sx is the two tube version of the 77Dx. The 77Sx uses two Eimac 8877 (3CX1500) triodes. The amplifier runs very quiet compared to other HF amplifiers that I have used. It doesn't take much drive to obtain legal limit power output. The amplifier is very large and heavy, and is beautiful to look at! Easy to hook up and tune up.
