Below is his achievements:

Hadley Laboratories 622C Power Amplifier, contributing engineer

Dynaco Stereo 400 Power Amplifier, Designer
Dynaco AF-6 AM/FM Tuner, contributing engineer
SAE (Scientific Audio Engineering)
XXXIB Power Amplifier, Designer
IIIC/CM Power Amplifier, Designer
IVD/DM Power Amplfier, Designer
VIB Stereo Tuner, contributing engineer
IC Stereo Preamplifier, contributing engineer
GAS (The Great American Sound Co.) Chief Designer
Ampzilla Power Amplifier
Ampzilla II (World's first servo-controlled power amplifier)
Thaedra Preamplifier (World's first (and only) servo controlled preamp)
Thoebe Preamplifier
Son of Ampzilla Power Amplifier
Thalia Preamplifier

Sumo Electric Co. Ltd. Chief Designer
The Power, World's first 450 watt/channel fully balanced Bridge Power Amp
The Gold, World's first patented solid state Class A Power Amplifier
The Nine, World's first low cost solid state class A power amplifier
The Nine+, Ruggedized version
Electra Preamplifier
Charlie the Tuner, world's first premium low cost stereo tuner (The humor in the name is that US TV advertisements of the 80's had a cartoon tunafish named Charlie selling cans of his relatives . . . and the tuner had quite mixed reviews.)

The Sumo I, Magnetic Phono Cartridge
The Sumo II, Moving coil Phono Cartridge
Harman-Kardon, Consultant, completely redesigned the Citation 23 Tuner

I am honored to have two of his great design namely The Dynaco Stereo 400 and Great American Sound Ampzilla II power amps. " If I were forced to cite one single project that can describe James Bongiorno's genius I'd choose the GAS Ampzilla power amplifier because, at that time, this represented a refreshing departure from the usual HiFi cliché's...this power amplifier was every audiophile's dream!"
More generally, his amplifiers and preamplifiers for SAE, GAS and Sumo were components that marked an era, for the originality of their design, circuit layout and price/quality ratio. He was such an eclectic designer and man.

I felt very sad when I found out about his death.  He was one of the earliest who pin-point against the cross-over distortion of audio amps on his work (The Dynaco Stereo 400).  He shook the Hi Fi world with his Ampzilla & Ampzilla II amps due to hi speed, and very wide dynamic headroom, price/performance ratio.

It is a great amp, can still go head to head against most amps today and kick some butts, hehe.  I got a feeling that the air tunnel hmmm...it's idea is from Marantz where Marantz borrowed from NASA.  It did not have the same problem Marantz once had.  (Seemed like a mounting issue of the fan that sometimes cause noise).  Overall, the air tunnel of Ampzilla is a better design.
