Akai 4000ds Muffled playback

Hi,
My 4000ds playback is (i can only describe as) muffled on both pre recorded and my own recordings, i can record on it and play the tape back on another machine and it is nice and clear. I have cleaned and demagnetized heads but no change.
I HAVE NOW SORTED THIS PROBLEM.
Thanks in advance,

solution

01. Clean the Recording Switches with cleaner

02. check the capacitors in Power Supply

03. check the Play Back Pre amplifier

04. some times All the Transistors will show good junction values while checking with the multimeter and If you place in the Circuit these transistors may not work because of its age. replace with original or substitute Nos.

05. Capacitors also may not function in the Circuit because of its age
