aiwa f770 cassette deck
Does anyone have any input on why on Play the heads and capstans do not raise to engage. Everything else seems to be working fine. Rewind and play motor works ok, and the other processes available for sense the tape bias etc is working but does not report anything, due to the fact the heads do not engage tape on play or sense or even record. If you do know any thing on the topic, is this goingto be a expensive fix or even a fix not assumable to fix due to age and part availability. If service is recommended, where would i send this unit. Obviously AIWA /SONY and age of unit would be tough especially out of warranty. I did download the service manual. Would a compedent service center be able to fix this issue provided parts could be secured. Being ignorant here just asking questions. There are not to many electronic service centers in Western MA except maybe in Chicopee MA.
Thank you for the time and cooperation to reviewing this and advance thanks if you have any input.
thank you for the great return response...
I am very surprised and encouraged with the information replied on regarding my Aiwa F770. Iam concurrently trying to digitize some older educational audio cassettes for my parochial school library and being that the company does not have CD equivalents, I was hoping to utilize the great playback of the unit even though I still from time to time use it to remaster some older cassettes once gone to the wind of better preserve it . Now I am considering whole heartedly to digitize my home collection to CD and or computerized file compatibility. Due to unfortunate timing of tryingto use my Aiwa F770, I had to use an older Sasui tape deck which exuded a hum on playback then even used a old GE Great Escape player which had developed auidble clicking in the playback motor and I had to filer each digital dub with Adobe Soundbooth. When it became noisier, I went back to using a older mom tape player/recorder from Radio Shack which has been archived in my drawers. Since it was momo playback, I used a set of cable to go from one and then split the signal to mono in 2 channel and then insert the audio in as a line in/aux feed on the sound card. I know as needing stereo since playback was originally mono. I then adjusted for hum and rumble then finally got rid of the hiss in the recordings. So far I am pleased, next step is to burn CD's of the wave files of which were recorded in 44,100 1bit stereo or 2 ch mono. then I will master a disc with mp3 quality as a redundant back up to the wave files too. Full project of 46 stories took 3 days of 12 hours each to edit and filter the audio. I will be glad to get the Aiwa deck to work again. It has appreciated in value to the point, it is surely a fineto keep running. I hate having to source one know on eBay. Seems the "educational " org's in USA have forgotten a niche market. Thanks again. I will keep you posted on restoration process. As for the belt replacement if needed, are the belts easy to findf still? I have noted a few sites which sell a multi belt pack.

I inherited one with the same prob. Its hardened grease not letting the heads come up. After some unlubing then some relubing, mines working fine now. Been awhile since I did it, but I seem to recall that there was extensive ish dismantling involved in getting to the affected area, but once able to access the slide arrangement that was sticky it didnt take much to get it free and going.
aiwa Ad-f770 head base does not engage
You must replace the 2 belts, one from capstan motor to the right capstan wheel, appr. 12,5cm long(fold), width 0.4mm , 0,05mm thickness and the belt between both capstans 11,2cm long(fold), o.4mm width , 0.05mm thickness, since by aiwa AD-F or XK- series the head base can be engaged the tape only with supports of the capstans with gears
