Finally all my blabbering about hi-fi gear at the local cafe has paid off, a barman decided to give me a TT he hadnt used for quite a while, he just wanted it to go to someone who would take good care of it :)

Its the Akai AP-004, dont know much about it yet, but looks beautifull with all the wood panels etc. Does anyone know when these were build?
I havent spun a record for years, i still have the first TT i ever bought when i was 17, an Akai ap-101.

It does have some bugs, all the automatics are very very slow and it doesnt shut off at the end of the record, would this be an electronics problem or mechanical?

G'day mate, I also have an Akai AP-004 acquired second hand many years ago and they are very sturdily built units. There is full information on that turntable in the library of the Vinyl Engine website.

It is rather mechanically complicated but mine has given very little trouble mechanically. A couple of the large capacitors on the motor board have dried up though and needed to be replaced. Good luck. Regards, Felix aka catman.
 
Thanks for that link Felix, think I already ran into trouble though, looks like i blew out my phono input on my sansui au-3900 while changing cables :(
 
Dont be all depressed over that..its better than blowing up your amp. Probably the rca cables. Thats usually the part that gives the probs on an older tt. Take a meter and check from where the cables attach under the deck to the ground and tip for continuity.Lay odds thats where your problems lie.
 
G'day mate, check the muting contacts on the Akai turntable. Mine gave that sort of trouble. Of course the interconnects could possibly be intermittently faulty also. I seem to recall that the Akai AP-004 had output RCA sockets. Regards, Felix aka catman.

Went to bed last night feeling bit miserable about this, today i wanted to do some more tests and low and behold....everything works fine again! :)

Dont understand what happened though, yesterday afternoon we tested it when he delivered it, all was fine, that evening I changed the cables to the amp for some longer ones, i had no sound at all, replaced the cables again with some other ones, only sound on one channel.
I suspected the phono input of the amp at first because i accidently connected a tuner to it the other week. The 'bare' end of the ground cable was also a bit long connected to the akai, it might have made contact with the bare metal of one of the connector plugs?

Anyway, glad it works again for now, will have a look at the internal contacts etc like you guys suggested to make sure, thanks for the info! :)

Hmm I reserve the right to change my mind..slightly. Maybe its a dirty input selector on the amp. That would cause a temporary dropped channel also. Just trying to cover all the bases here..however I defer to Felix as he has first hand experience and way more electronics experience than I, plus he has experience with that particular tt and I dont.
 
I only had this amp for a few months, didnt clean all the knobs and switches, only the treble which had 'crackles' in it so maybe you are right.
I also still have the suspicion that connecting a tuner to the phono input by accident some weeks ago might have done some damage but im not, i dont know enough about electronics yet. But it all seems to work just fine now.

I cant really recall the sequence of events of what i did last night that might have caused it, one lesson to be be learned from this that i shouldnt be messing around with cables etc. late in the evening! :)
