My dad had exact same one he bought new. Around 1983 it had an intermittent issue with only recording on one channel. After several unsuccessful trips to repair shops the problem was discovered to be the long slide switch that activated the record mode which at the time was unobtainable.
That was the tape deck I purchased at the Subic Bay Navy Exchange while on board the USS Constellation CV64 with VS-21 during my first Westpac 1977! Kenwood KR5600 receiver, Kenwood 16 Channel graphic equalizer, Kenwood K777D 130 watt 16" woofer speakers and a Technics 1500 turn table. Can't believe I remembered all that but seeing my old model tape deck in your video brought back some memories!
@@mguess I still have the Technics turntable and all the albums I had ever purchased. Really should have kept that old stuff including my "68" Chevelle SS 396 that I was still driving at the time! Living large back then and didn't even know it! Lol!
Thanks for the comment and good luck with your restoration. I use my Akai deck often. Mostly playing my old cassettes and transcribing tapes to digital for friends.
How did you replace the "big" belt, that goes from the motor shaft around the beefy pully? Did you have to disassemble the mechanism to slip the belt around? I was able to replace my other belts, but not that one (yet).
All you have to do is undo the screws on the back plate and then the pause part and plate comes off allowing you to put the main belt on then u just have to screw it back on and put the pause thing back in place
Remove phillips on plate behind pulley & loosen 2 6mm nuts @bottom of said plate to slip belt around pully & attach 2 motor turn by hand til runs strate & tighten all back up . Tedious but im not electronic guy good luck.
I used 4-40 nylon screws 1/2 inch long. I cut the heads off of the screws to adjust the length. I don't remember the size of the hole. I think I just tried different drill bits in a scrap piece of plastic until I found one that worked properly. The nylon screws are still working fine 2 years later.
Unfortunately I didn't record the belt replacement process. It wasn't that difficult as I remember. You can order a belt kit for the CS 707D online. You will probably spend more time removing the black goo than replacing the belts.
@@mguess yeah I had the belt kit on hand. Still trying to get the goo off my hands lol. I got the belts done after a bit of fussing, but it seems I have another issue... I hit play and it stops after 1 second of play as if the tape is ended.
It sounds like the "end of tape" is being detected. If I remember correctly the end of tape mechanism is related to the tape counter. Is the tape counter moving when you play a tape?
@@mguess It is counting. I think I figured it out. There is a .5mm wide belt that runs from a large drum that turns the needle at the bottom right of the cassette. That belt is completely desintigrated and turned to goo. So without that needle turning, the tape is being pinched between the needle and roller.
Good idea to change all the belts. After 40 years or so they tend to start the change over to goo! Good luck with your vintage Akai, great little deck.
@@mguess tape plays normal but music sounds like a cd thats skips as peak flashes and meters bounce as in time w/ the interference listening in h- phones .
Sorry about that. I forgot now why I didn't record the belt change. Sometimes I just get busy and forget to set up the camera. Thanks for commenting on the video.
