![]() They also handle sales for Sony Direct Car Stereo's. The only reason I mention Crutchfield is becasue they have the best online Database for verifying that any given audio product will fit. So if you can't get it fixed then I would not hesitate replacing it.Ĭan't remember the user who sugggested it but Crutchfield is the absolute best for you to buy a new deck from, simply because they will supply the oversize Storage case and wiring harness for free. The guy had to pay 11 bucks for shipping but it worked great. I replaced my Deck in my 90 legacy and then sold the stock deck for 1 dollar on Ebay. But I think the lack of volume is now after the head anyway.As for the Question, I would attempt to retrieve the tape with some Butter Knives or hemostats sp? Anyways, also think about what you make an hour. I could not get Deck 1 head to play via deck 2 amp, as they are shut off when the other plays. The signal must be good after that stage. As you can see from the part schematic below Deck 2 signal joins it at pin 2. And Pin 1 has the correct voltage U302 TC 4066 has 6 volts at 1 and 6 volts at 2. Just over 3 volts as shown comes out of pin 3. I checked the voltages U301 does get the 9 volts at pin 4. All connections to the head are good anyway and the fact you can hear the sound from the head means it's good the preset controls R11 and the other for the other channel do adjust the volume and if turned up full the signal is just loud enough to be hear. So it would appear that the problem is on the PC board. Whereas if you remove P1 for Deck 1 you can only get a buzz by touching the pins. Even putting my finger near the P2 connector caused a great deal of hum. Even with the headphone volume control on half. Even with the head connection off you could hear the background hum of the pre-amp stage. I removed the Deck II connector P2 and pressed play on the deck. Is there a thread for it already or should I start one? Has anyone encountered sticky cassette tape problem? Where the cassette will just stop moving, regardless of tape machine? But the problem would be when deck 1 is running deck 2 is shut off and vice versa. I couldn't directly fit the three pronged head lead from deck one to the Deck 2 connector, but it might be possible to take a wire from the pin of deck 1 head to deck two output, at least for one of the channels. The good thing about the deck is that all the wired connections are done by sockets and mounts. Is it possible to jury-rig the switching, and feed to 'bad' head output into the good deck's connector, while energising the 'bad' transport? That would narrow down the possibilities. The normal output of tape heads is pretty low, so the fact that you get hum when you touch the amp input doesn't mean very much - the gain might still be lower than it should be.Ĭan you arrange some sort of signal via a potential divider, and compare the output levels when injected into the head connector for each deck? So I am assuming the head is the problem. As I am hearing sound from the tape, it shows the switches are passing the signal. I can get a buzz from each channel by touching it with my finger. If I remove the head lead from the connector bit. There is also a small capacitor to the power of the IC but that is good, plus a replaced it too. But on deck two it's loud at half volume.ĭeck 1 uses a separate IC a UPC 1228H as the pre-amp but I have replaced this already and it didn't make a bit of difference. I can just hear the music playing from the tape. But Deck 2 is normal.Īt the moment I am using the headphone socket to listen to both and with the Headphone volume control up to full level. The problem I have is a dual tape deck a Marantz SD 285, deck 1 (play only) has a really weak signal coming from both channels. The question is can you still hear sound very faint from a bad tape head? I have a question about cassette tape heads that I couldn't find an answer to on the net.
