Hi,
Thank you for your suggestions and kind words,
I had further tried to clean the heads that now look much-much better than before, but I am afraid some corrosion signs are remaining on the metallic part of a couple of heads. Passing a finger I can not really or barely feel these "damaged" parts; if I gently pass a nail I can feel them.
I am taking in consideration to look for JRF Magnetics assistance if I can not fix the problem by myself. I have contacted them and asked if it is possible to send them the entire head assembly hosting the 6 heads, as one of the problems that I will face removing the heads one by one is to find locally a good professional for a proper reinstallation & alignment (not really available here!) once the heads are back.
John (from JRF) kindly made himself available, saying that I can send the complete head assembly, and they will remove the heads, re-install them and optically align the complete head assembly. After this he would send the entire "block" ready for reinstallation.
Should this happen, this is I think the only solution for works to be done on the heads, because as said in my city I can not find a professional able to make such works properly or without making experiments on my Teac X-2000R
BEFORE going for the above solution, I will for sure try the solution you have just proposed (the tape cleaning solution).
If results won't be satisfactory, what do you think about sending the entire heads assembly to JRF?
Also, and very important, do you think that demounting the entire Heads Assembly is something that can be actually be done on a Teac X-2000R? Could you kindly provide some guidance on this operation so that I can do it? I have 16 years background on mobile units? assistance, so I am not really a beginner and used precision tools in the past.
Thank you for assisting me; I really appreciate it.
Regards,
Fabio
