I went to turn on the tape deck and it shows the tape is playing, but there is no sound out of either deck. All the connections are good and I have cleaned the heads. I lost the manual and cannot find a place to download one for free. Any suggestions. I don't use it that often, but the last time I used it, everything was fine.l

Re: No sound on cassette deck
Does the deck have VU meters?...or a graphic display of some kind to indicate there is sound being picked up from the heads?
If there are, and they are not moving or flashing, as the case may be, then you could have a wire off the head, or a problem in the preamp circuit, or if the deck is older, it could be as simple as a dirty play/record switch. I would need more info to help further.

The Bias control is used during recording. If you turn down the bias,
you will get more highs, but the distortion will increase, and then
start to increase dramatically if you back off the bias more.
As far as playing tapes from different decks goes.......
1..Does the tape that you recorded on your deck sound OK on your deck ?
2..Does the tape that you recorded on your deck sound OK on other decks ?
If 1 and 2 are true, then your deck is OK.
If the tapes recorded on a specific deck sound bar on yours, but 1 and 2 are true, then the other deck is faulty.
When a deck leaves the factory, the head is aligned to a " standard "
tape. By standard tape I mean a very special tape recorded in such a
way, that a tech can tell if the head is out of align and "tweek " the
physical alignment of the tape head..
All decks are aligned just a little differently, but fairly close to each other.
first do the mechanicals....is the head of your deck spotlessly clean ?.
Use 99% pure isopropanol alcohol and a cotton swab. Never use anything
metal to clean the tape head. If you scratch the head, its toast.
If your deck is clean, plays its own recordings well, and those
recordings play well on other decks, then your deck is not the problem.
Sounds like the cassette tape itself is too tight to play, try fast forwarding or rewinding the tape in the deck all the way to the end of tape several times before trying to play. This may solve the problem
There is an outside chance your tape cassett has a static charge. Tape in plastic case of cassette can build up significant electrical static which can partially discharge as tape is run. It can sound like random thumps, ticks, pops ect. Wrap cassette in a damp (not dripping wet) cloth, for several hours, then try again. This can also happen to the reels and drive rollers of the deck
Ahh, Another Dual cassette deck. These are typically not worth a repair charge. I went looking for a service manual but Hi Fi Engine did not have one but they had a Owners Manual. Any unit that has a specification as to wow and flutter starting new at .18% was never made to be a long lasting deck of any quality. I don't like to be negative about people equipment but you might be better off getting a better deck from the start. If you think it is worth the repair, then send it to someone but I don't think you will want to sink $100 into a unit like this. I am not saying it is unrepairable but that with what you come out in the end you could have made a better choice for a deck to buy. It is probably a bad solder joint or bad capacitor on the circuit board. I am in Chicago and would look at it for you if you want.
