I've had this deck for sometime now, it has a good sound from all types of tape. The only downside it doesn't have a reverse tape mechanism.

Denon DRS-810 Cassette Tape Deck

My tape deck hasn't been used in several years. I recently tried to play old cassettes but it stops playing after 8 seconds. Does anyone know what the problem might be and is it worth the cost of repair?

Solve the problem with new belts

You must replace belts with new and thats all. Several years doing your original belts like old socks!!!

Tape deck stops playing after 8 seconds

Hi, my DRM-740 had the same problem and it was basically due to loose belts. I found a video on Youtube that explains the problem, but unfortunately, it doesn't really explain how to make the repair. So I sent my unit in for repair. New belts, cleaning, and aligning to spec will cost about $75 here in Los Angeles.

Denon DRS-810

Just to mention (as not mentioned in the item's description): This is a 3 head deck and 4 motor (as indicated on the front panel). 4 DC motors. Actual motor functions are: 1 capstan, 1 winding (gear driven with rounded teeth for even torque distribution), 1 to move the head assembly, 1 to open / close the drawer (Yes, the tape loads like a CD player in a drawer (horizontally), which makes it impossible to manually clean the heads without taking the deck apart - use cleaning tapes for day to day use). But a nice quality good sounding Hi-End deck otherwise.

Even on your 4-motor deck,

Even on your 4-motor deck, the index counter is more than likely belt driven. The index counter is also where the auto-stop sensor is likely to be located. Replace that one little belt.

Also, most good machines like that, (and Denon would be a "good" machine), there should be a function to open the drawer for cleaning and maintenance. Hard to believe that Denon would omit that function. (But they might.)

re: Even on your 4-motor deck,

You can open the drawer. But, the design of the Denon DRS 810 precludes cleaning the head in the usual manner.

Think of it in the same manner as a VHS player/recorder. Either you use a cleaning cassette, or you take it apart to clean it.

re: Even on your 4-motor deck,

As far as I know, the DRS-810 has a door in the bottom cover that will allow access to the heads.

re: Even on your 4-motor deck,

That is correct. You remove the small compartment on the bottom of the deck and you will have access to the heads for cleaning. Great machine, it rivals my Nakamichi decks!

re: Even on your 4-motor deck,

The only way to reach the heads of a DRS 810 is to remove the top cover, remove the clamping mechanism (no tools required), depress the three plastic arms in the near right corner, and then press play. Now the head carrier will engage and the rollers will engage. Not that the capstans will not turn when play is not engaged, unlike most other decks where the capstans start running when you press power.
For demagnetizing the heads can be reached without engaging play, which is good news, because using a demagnetizer with a powered on deck is...unwise.
