![]() ![]() ![]() There are 2 further screws underneath which hold the front panel. You pull forwards from the bottom to disengage the top clips and the trim can be removed. First the aluminium trim is removed via 4 screws on the bottom and 1 screw on the top. To remove the cassette mechanism you have to remove the front panel, which comes off in 2 parts. It’s rare for the electronics to fail in these. Its simplicity means it is also one of the most reliable cassette decks you’ll find. This is a simple cassette deck and the electronics are therefore sparse, though there are plenty of calibration pots and test points. You can also use products like Platenclene, designed for rejuvenating printer rollers, to restore their grip. Besides the pinchroller of course, but those don’t seem to degrade and respond well to being submerged in hot, soapy water for an hour or so. Fortunately this mechanism is easy to service, and besides the three belts is entirely gear-driven so there are no rubber tyres to worry about. It is essential that all of this residue be removed as not only will it negatively affect performance, but it will cause new belts to degrade. Few substances will shift it, though acetone (careful not to get it on surrounding plastics), 99.9% isopropyl alcohol and WD40 will break it down. The rubber degrades and turns into a black tar-like substance which sticks to anything, including mechanical parts, motor and flywheel pulleys, and yourself. This issue is common in some equipment from the 1970s and early 1980s, particularly equipment of Philips, Sanyo and Toshiba origin. This deck was suffering from degraded belts. It makes sense, as speakers are essentially boxes of air so manufacturing them locally would save on shipping cost especially when you’re shifting a lot of units. I’m told that the speakers were manufactured in the country of sale – for example speakers supplied in the UK with the M20 system were made by Goodmans. As vintage hi-fi goes they sound very nice indeed and are well made components too, as you’ll see herein. Sadly most of the complete systems have been separated so it’s rare to find a full setup. There’s very little info online about these systems as a whole, though their components individually are often available on the used market so they obviously sold well. The system comprised the SB-M20 amplifier, ST-U20L tuner, RS-B20 semi-automatic turntable and one of several choices of speakers, plus a cabinet. The Toshiba PC-G10 cassette deck was sold in 1983 as part of a Toshiba ‘Rack system’. ![]() This entry was posted in Cassette Machines and tagged Cassette Deck Repair Toshiba on by Ashley (updated on May 17, 2022) ![]()
