![]() A few of the tubes needed to be replaced a 6AL5 had one diode giving no emissions, a 6V6 was very weak, and the 6CA4 rectifier tube was shorted. The can cap was replaced with new under-chassis capacitors on a terminal strip as well. Portable DVD players.Īll but 4 resistors ended up being replaced in the amp section. Testing the resistors in the power supply and amplifier sections, they were drastically out of their tolerance, and one of the resistors in the feedback network on the voltage amp was damaged which would have prevented that side from demonstration proper gain.īlu-ray and DVD players. Other than that, though, the repairs were still 40+ years old and were due for re-work. This one had been serviced a couple of times in the past, including the amplifier section where someone had replaced a pair of the coupling capacitors with new Orange Drops. When properly adjusted, this amp produces about 10W per channel. These are dual-chassis consoles, with the power amplifier and power supply on one chassis and the tuner/pre-amp on the second one, with a total of 13 tubes, including stereo push-pull 6V6s for the outputs. He’d had the console for a while, working but with some trouble, but wanted to finally get it back to top shape for some more daily use. From: A customer recently brought me the guts from his Magnavox 1ST611R mid-century stereo console for an overhaul.
