CTF-750 Recording Issue

Hi,

I'm trying to renew a ctf-750. I changed the belt and quite all the capacitors.
Playback is ok. Recording don't work:
Erasing is heratic, sometimes it records, but i need to put the record volume to a high level, the sound is bad in that case.
Can help ?

Thanks in advance,
Rgds,

Hi,
Seems that the erasure bias current has a problem, i should see 150mv , and i have 45mv ?
Turning the vr304 (erasure bias current adjustment screw) change the things a little 43 to 48mv!

Rgds,
