Apt Holman Preamp & Model 1 Power Amplifier ~ Prof Serviced

Description

Apt Holman Model 1 Amp & Apt Holman Pre-Amp
Pair vintage Power Amp and preamp
The APT 1 amplifier
is a truly advanced product and even by today’s standard, a very modern audiophile amplifier design. Some of it’s design technology is only now being implemented in fancy name equipment. Seldom are so many of it’s clever design tricks for correctly stabilized feed back circuits, optimized impedance matching both at input stage design, power supply and output amplifier circuit have been utilized in total (even compared to fancier products.)
The Apt Corporation's Holman Preamplifier
is the most well thought-out stereo preamplifier ever designed.
It was designed at the very height of recorded music's reign as the dominant form of home entertainment (home video was still years away), and was designed by none other than the brilliant Tom Holman, the inventor of 5.1 audio and the inventor of THX motion picture sound.
More important than its stellar laboratory performance is the fact that this preamplifier is designed to do exactly what's needed to make music, and a music reproduction system, sound great. This preamplifier even has a patented variable stereo expansion circuit, a foreshadowing of Tom Holman's later exploits into multichannel sound.
tested extensively - works well and sounds great.
