Myst Amplifier Repairs

Myst TMA3 Stereo Amplifier

The unit had been unused for approximately 30 years, so I did not apply full mains power immediately. It was initially powered through a current-limited supply, allowing the equipment to be brought up gradually while monitoring the supply current and checking for any abnormal behaviour.

The amplifier powered up normally and, following the initial checks, appeared to be operating correctly. It produced a good clean output and proved to be a very good-sounding amplifier.
