![]() Hi.... Picked up a Technics SL-BD22 on Ebay. The tone arm is supposed to return to the cradle at the end of the record or when you press the Stop button. Unfortunately, it doesn't. Otherwise, looks new & sounds quite good with the Grado cartridge. Can anyone advise a way to troubeshoot/ fix this when I crawl in there? Any websites offering advice or pictures? Thanks in advance....Mike |

Could be as simple as the pusher wire, which engages the lever that works the gate on the main gear, has become displaced, such that neither the tone arm, nor the stop button, cause it to move.

You answered your own question, You bought it off Ebay. I've bought tons of stuff on eBay - rarely any problems, though I don't really consider normal maintenance on 30 year old equipment to be unexpected. The worst I've had were a couple pieces where the condition was overstated (as "good" when "fair to poor" would have been more appropriate), and a Tandberg open reel with lube problems. Anyone who knows Tandberg at all should expect them to be maintenance intensive anyway, so I wasn't too upset. Mark Z. |

In the later, solenoid operated Tandbergs I've seen , the pinch roller mech always has hard grease on and needs stripping and relubing or the unit won't rewind; I've also seen 'em suffer from spasmodic logic due to the 33v rectifier, and the odd BC147 transistor. As for the older mechs like the series 14, 15 etc, they seem to rarely give any problems . Real workhorses. I wouldn't say Tandbergs were maintainance intensive at all. At least no more or less compared to other r2r makes I've used or worked on....Ben |

Brakes crumbled, belt sagged, regulator transistor opened up, lamps died, motor overheated from bad lubrication, power switch went bad, I forget if there was any other problems. I've fixed it more times than I can count. Had a 9200XD. Bad frequency response on one channel (since new), Dolby relay would go off by itself, record inhibit IC went tits up, then after I got it all running again, it got stolen. Had my brother's old 3300X for a while. Replace the bad euro capacitors since they were failing (getting hot, bad sound, etc) and cleaned the connectors, replaced the belt. As soon as power was applied one of the BC transistors failed immediately, pegging the meter. Had another 9200 XD, had the usual tarnished connectors, lamps out, and bad lube. I have a 10XD which I haven't even had the heart to get into. Mark Z. |
