My initial plan was to get the tuner rebuild for Euro bandwidth.. I got the Japanese servicemanual etc. And thought I found a tech who could do it, but after studying the servicemanual he told me he is afraid he can't get it right, he finds the APC circuit on the F3 to difficult, he asked me to find the servicemanual for the same tuner but than with western bandwidth, however.. the F3 is japan only.. The closest thing it could come up with, is the F26 tuner, however I can't seem to find any servicedocs on that one.
So, for now I have find another solution: I use a bandwidth expander (the Merlin, can be found on that auction site) which is build for in-car use. I did a small conversion, so I could power it with a 12v adapter.. and cutted of the original connectors. It works like a charm! the sound output is very clean and crispy, no distortion whatsoever.. Ofcourse there is still the issue of the dialscale, but I can live with that for now..
My plan to get it rebuild still stands.. but I'm not sure if I will ever be able to get it done, it all depends on the availability of the right person and docs. Changing the dialscale shouldnt be to hard: I just have to get someone to cut me a glass plate in the right size, and then (after measurement etc apply the print.
There is a guy in the States who has some expierence with rebuilding Accuphase T-102's ans Sansui TU-9900 and TU-X1's.. He can do it to your Kenwood as well, I'm shure about that, but it will be pricey...
