Vintage Michell Gyropower QC // AC Power Supply

SOLD , now part of a Private Collection

In the early 1990s, Michell began to realize that motor vibration could be reduced and speed accuracy improved by the addition of a better-regulated power supply. The Gyropower QC is Michell's second-gen active power supply, generating two sine waves from a quartz oscillator and amplifying them through two power amps. Although there are two small dimples on the top the transformer cover, this unit tests as though it just left the factory, and is one of the most effective performance upgrades for pre-Orbe Gyrodecs.

The History of Michell
In the late 60’s, the company started to make parts for Transcriptors who subsequently re-located to the Michell premises. At this time, Michell were still supplying other local firms as well as working directly with the film studios making models and component parts for films such as Star Wars. When in 1973 Transcript...

Liner Notes

A far more sophisticated power supply than the original passive Gyropower, this was a fully active design that provided the precise 50Hz power feed that the GyroDec’s 24V AC motor required for optimal performance. The QC used quartz-clock synthesized sine waves to generate the current to drive the motor coils. Speed changes could now be accomplished at the push of a button, eliminating the need to fiddle with drive belts and motor pulleys, and the significant reduction in motor vibration greatly improved overall sonic performance.
