I would like to say good afternoon but i may have a problem.
I've been working in my brothers shed while he is away. Today i realised i put one of those car subwoofers with a huge magnet next to his Denon platter which is one of the type with the magnetic tape on the rim for speed control. Would this magnet have affected the speed control thing? Its his pride and joy and I cant test it because the deck is locked in the house.
Hoping for a positive outcome, sp

That platter's done now, history.
The magnetic coating inside the rim is critical for proper operation.
Too many people have messed around and damaged that coating, scratching it, aggressively cleaning it, and yes, placing magnets near it.
In my opinion of those Denons, that was the stupidist design I ever saw.
They're troublesome machines, over-done in the electronics/contol area.
I was given a pristine DP-59L years ago, and quickly unloaded it to a buyer, I didn't want that damn machine around.

Yes, i think I'm going to have to move on and think of something over the next few weeks before he is back.
Thanks all, sp
PS wiseoldtech, i agree. I remember him telling me about it and thinking it was a dumb idea at the time.

It is not a forgone conclusion that the magnetic strip is damaged. The rim of the platter is significantly thicker than the plate. It may be enough to have protected the pulse strip. The type of magnet on the speaker determines how quickly the gauss field reduces with distance. The direction of field contact would also be a determining factor i.e. above or at the side. If it is damaged you might pick up a replacement from ebay. quite a few models had the same platter.
There was once panic in a studio when someone stored tapes of a major recording artist on top and around a speaker in the manager's office, awaiting arrival of the band. Some tapes were analog, others digital. None of the tapes had noticeable damage. I have a DP-30L using the same method and works as intended. Re-sale value of Denons is healthy which wouldn't indicate a generic problem with the magnetic coating, although I imagine a good few got abused over the years.

Hi spladski I hope you are right because I have a happy/sad update.
My brother called me and it turns out that the reason the platter was in the shed was for a quick check before he took the deck to his holiday house. He was pissed when he realised he’d forgotten the platter but even more pissed when he dropped the deck going up the entry stairs smashing the plinth and arm. He said he threw the lot in the bin but later decided to call me to see if I wanted the motor part which apparently is in one piece.
Of course I said yes so I’ll soon see if it is working.
He is buying one of the new technics sl1200 which is why he was taking the Denon on holidays.
Anyway it could have been worse, sp

I don't know if your floating island is 220V or 110V. The 110V is simpler and if the circuit board is intact, you have a project. If the motor is the heavy aluminum-can AC version, it is very robust. You don't even need to implement the servo if the read head has gone missing. Vinyl engine has service manuals. The Denon model was not mentioned. If the model has motorized arm lift solenoid, it is a killer feature, much under-rated. If it is still in the bin, go find it and the circuit board.
