hello,
my old grundig receiver R 2000 is not able to keep fm frequencies stable. I think the voltage for the cap-diodes is variing. I've been told that the most probable defect is to find in the voltage stabilizing IC TCA530. It turned out, that this IC is very rare. Even Grundig developed a replacement circuit on a small board. As far as I know other people have the same difficulties with similar audio devices from other brands such as SABA. Does some know a source for this IC or does he know the replacement circuit? I would be very glad to get a positive answer. greetings hans p |
