Akai 4000D - Erase Head
I'm very new to this so please forgive any stupidity/naivety. I picked up my first reel to reel the other day, an Akai 4000D. My dad had one when I was young but would never let me use it so I'm really happy I got one of my own at last. It seems to playback well and everything seems to work except for the erase head. When I try record the existing recording can still be heard and does not go away. The new recording can be heard over this.
I checked the head out and there was a loose wire which I re-soldered into place but this did not make any difference. I've read quite a few posts here on HifiEngine and also on TapeHeads.Net but nothing that answered the question specifically. I was wondering if anyone could tell me if the erase can stop working completely or if it can be repaired or if there is another mechanism that could be damaged. I'm not confident enough to do this myself and am therefore also asking for any advice about getting it fixed.
My apologies if this is not the right place to post this kind of question. If anyone can point me in the right direction for a solution I'd be very grateful. I'm based in London so if anyone knows of somewhere local that could fix the deck for me that would be great.
If you need more information on the problem I'll try to answer.
Any help or guidance you can provide would be really helpful. I'd like to see the 4000D back to it's original glory if possible.
