Sony TC-K590: capstan-motor always running when power is on?

Sep 09, 2007 6 Replies

Hello! I got a Sony TC-K590-tape-deck. It seems to work ok, only one thing is strange. The capstan-motor is running as soon as the deck is powered on. Even without tape, door open/close doesn't matter. No "need" to press play for it to start running. First I thought it might be similar to this problem:

But here there was action even when it was powered down. Also my backlight is dark/normal. And the faulty resistor mentioned is not the same value in the K590 as in Alans K620, so they might not be that similar. I got the thing used and in this state, so I don't know if it always did this. Does anybody have an idea what might be wrong, or even how to fix it? Or is this maybe even normal? I've never seen that on another tape and it doesn't seem to be a healthy behaviour. Thanks a lot for any hints. All the best, rob

I've a Teac that the capstan powers up with the on switch so that part is not abnormal for some decks, especially higher end units. Can't comment on the other problems you perceive.

I can't think of any good tape recorder I've owned that _didn't_ run the capstan motor all the time. It simply makes sense.

Oh. My other non-crappy recorder (onkyo ta-2550) doesn't do it. Thanks for the info (also to Meat Plow). Care to explain why that makes sense? The downsides are that it wastes power and make (soft, but anyway) noises. What is it good for?

Thanks & all the best, rob

The power waste is minimal, because people don't usually leave their tape decks turned on without playing or recording.

The practical advantage is that the capstan is "guaranteed" to be running at the right speed when the tape starts moving. That's something you'd expect from a "professional" (or "good amateur") tape deck.

for?

The capstan motor usually has a fan blade to cool the deck.

If I remember correctly, the capstan runs all the time in your model type. Many types of tape decks run this way.
