I've bought this amazing denon dp 60-l turntable used about twenty years ago and it's the envy of all my audiophile friends. After years of faithful service one day the platter strated slowing down and now it won't rotate at all. All the lights come on and I have sprayed the inside circuits with "de-ox" which brought it back to life temporarily. I took it to a local AV repair gut here in Napa and he told me it was impossible to repair and was essentially a nice looking paper weight(cost me $35.00 to hear this) My wife is wanting me to "get rid of that thing" but I am stubborn and want to get it working. Any advice would be greatly appreciated.

If you aren't giving up you have to replace all of the electrolytics capacitors in that table. Electronic components are designed to only last so long and the lowest life span of them all is the electrolytic capacitor. That generation Denon turntable is a servo controlled DD model that is controled by a custom Denon speed control microprocessor. Hopefuly you haven't fryed that microprocessor or else that table is a doorstop. Assuming that the microprocessor has survived your use of that table until it died, you can have the table recapped for a reasonable amount. The cost of the replacement electrolytic caps is around $40 USD (if you buy the caps and do the work yourself) and the labor is whatever the particular repair shop charges. While you have them recap the turntable you should also have them solder all of the wirewrap connections. The wirewrap connections on old Denon turnntables cause more trouble than you can count so eliminating them is a wise thing to do. The table will then require a servo readjustment which requires a 10mHz dual trace oscope. If you paid attention to what has already been written the servo system also depends on the strip under the platter where speed pulse information is recorded and the tape head that is mounted unde the platter to read those pulses. I'm pretty sure that the Denon DP-60L has its drive transistors seperated from the pre-drivers by opto-isolators and spraying around deoxit around under the turntable was probably a bad idea. Its never a good idea to start blindly spraying around cleaners like deoxit on electronic circuitry. Deoxit is made for specific things and spraying it on circuit boards is not one of them. One other thing...you have been a BAD BOY!!! Never and I repeat never run a turntable like that Denon until it dies. You are asking for trouble to run any piece of electronics blindly without regard for maintenance and the Denon turntable is no exception. We love turntables and vintage gear and you are now required to buy each and every member of this forum the LP of their choice. OK...thats out of my system. Go to your room, Ed Life is analog...digital is just samples thereof
