I have an AKAI X-1810D tape deck that does not auto reverse with the sensing tape in place on the tape. Also, is a repair manual available on-line? Any assistance is appreciated. Larry

    Thanks for your response. I tried your recommendation with no positive result. Also, the manual reversing function (buttons) have no effect either. Any more advice?

    Yes, the deck plays. Just can't get the reversing functio to work--manual or auto. I'm the original owner of this system as I bought it in 1972 while with the military in Korea.

Just a guess. Have you cleaned the two conductors on the sensor? You can test its function by running the tape in either direction and shorting it with a non-ferrous metallic object, say, an aluminum. You don't want anything magnetic near your prerecorded tapes.

    Your latest input regarding the failure to reverse under switch command is the FIRST thing we should have considered. Combined with the sensor issue we probably have a logic failure to drive the solenoid(s) that change transport functions. Does it even Play?

    So does it still Play Forward and Rewind / Fast Forward? I hate to say it but 38 years is a long time for a fossil to keep on keepin' on. I mean the machine, not you. I'm only a couple of years behind you and I had a Teac A6300 that would skew the tape off the capstan in reverse so I stopped using the Reverse function. That may be your only economical option unless someone with the specific expertise chimes in.

    Yes, it does all that. These machine are much better than those nerwer models. I also have a Sansui 8080DB Stero Receiver along with a Pioneer PL-530 Turntable which are fully functional that I purchased in 1977 while with NATO in Naples, IT. I've been searching for a business/firm that does overhaul/refurbishment of these type system with no avail.

    Thanks for your support!

Where can I download a Service manual for AKAI DS4000 Mk-II

Hi Fi Engine is one place. The deck will have a disintegrated cam and might be a waste of time. MOST all Akai heads are worn out at this time and there are no replacements.

My Akai X-1810D reel to reel has basically no volume coming out of the speakers (when I put my ear next to the speaker it's barely audible) Manual says it could be Diode D3 (10DC-1) Where can I buy this...

You need to be sure of the correct failed part and I would not jump to conclusion without measuring a power supply failure or lack of audio after an amplifier stage- Akai was known for use of some bad transistors. I have had to deal with them myself. It is unusual for two channels to go out at once. It might be wise to treat all switches and pots with Deoxit spray which may resolve the issue without a part change..

The sensing tape must be fitted at the end of the reel just before the coloured leader tape

I am not an expert in the repair of Akai units- most of the time I refuse them, however just to put you on the right path, the hum is coming from a power supply issue in the record audio section or may be in the bias section. You may need to put new Electrolytic caps in the power supply to resolve this. You can also scope the supplies on this deck to find the cause. I commonly work on Teac, Pioneer, Otari, Studer, Sony and better made decks. Some brands are real trouble and are more costly to repair due to poor construction.
I have been doing repairs for 40 years so far.

How to check if Auto Reverse Works

Play a tape to the end. If it reverses, it is working properly.

Make sure that you have turned the auto-reverse feature on. The switch is next to the power button.

I'm pretty sure the auto-reverse is NOT supposed to work during recording. What would be the point since it only records in one direction?

And I'm pretty sure there's only one reverse sensor, usually to the left of the heads and not necessarily on a tension arm. The sensor foil is supposed to be on the non-oxide side of the tape so it will adhere better and never contact the heads.

This picture of a GX-635 shows a typical transport ...

There's a knob for how the auto reverse. Is it set correctly? I believe infinite forward / backward play is possible if you have the knob set properly, a sensor foil on the tape and the tape counter set to 0000 at the beginning of the recording.

Just want to know whether there is a way to get a tape to auto reverse on the dual tape deck, and, what is the "OSD" button on the receiver for? This is an old Denon D-1250 shelf system. Thanks,

OSD = On Screen Display

Auto Reverse is a built-in feature of any tape deck. It would have a button that looks like > for forward and < for reverse; and probably a switch that sets the mode for automatic or manual reversal at end of tape.
