replaced - no change

Hello again, being very happy with the 9141TC that I've managed to revive with your help, I've sourced a defective SABA 9260. The price was reasonable so I took the risk .... The unit came assembled (with a lot of screws missing) and one "Triber" in a plastic bag (a lot of components bent / damaged mechanically). Upon inspection the unit was quite dirty - looked like bread crumble all over the mainboard and some liquid spillage (Could be coffee). Some kind of recap what done in the past - lot's …

I've inspected the FM board and found 2 solder joints cracked - re-welded and it works fine on radio. saba-forum.dl2jas.com/index.php/Attachment/6444/saba-forum.dl2jas.com/index.php/Attachment/6445/saba-forum.dl2jas.com/index.php/Attachment/6446/ Occasionally, one channel stops - no audio, but background noise. Happening on Tape 1 and 2... I'm using it every day so I'll keep an eye on it to look for any misbehaviors.

Zitat von kugel-balu: „One speaker muted -- also on the second set of output ? I'd first check the relay, unless you changed that already. Most of them are corroded by now. Cheers, Michael“ There is no click/relay noise - it just turns off. Slightly pressing the stereo board and the speaker is back on. I'll give it a try on all sources to see if it's related to FM mode or to all modes.

Thank you also for support. It worked fine but there are moments when one speaker gets muted on radio - fiddling stereo board, sound turns back on both speakers. For sure I need to spend some time with the board under microscope to look for some cold solder joints or maybe broken ones. PS: I've got my second SABA (8061 Telecommander) in reasonable good shape but it does require some attention . It was about 20eur so I couldn't leave it behind...

Also P512 was broken.... replaced it and did the tuning in parallel with another Tuner that I have (ST-J75). Picked a radio station on 89.2mhz and tuned the P512 to get best signal. Picked a station at 107.3mhz and tuned the P516 for best signal. With some fine jiggle of P901 and P911 and I have Stereo (with green light). It sounds great!!!!

I've found that P901 was broken therefore I've replaced it. Tried with a little jiggle (left - right) but no stereo signal on radio. When tuning there are moments where stereo led turns green but in that portion the signal is bad (look like an offset). When using another source, the signal is stereo so I think that the tuner itself has some problems.

I'll give it a shot these days and I'll let you now if I manage to improve something.

On Phono the signal is processed in Stereo, therefore I suspect that only FM module has some problems. I've seen that is quite complex to align it and I don't have the tools for it. I'll just clean some contacts to see if there are improvement and I'll guess I can leave it as on the FM decode. I must admit that I'm quite surprise by the quality on the Phono input - preamp is better than my Pioneer A550R. Sound is more profound (same speakers used - Wharfdale).

PS: all the SABA's have that many soldering flux residues? Mine looks like a full bucket was dropped on it. I've wasted half a flux-off can to clean only the areas that I've worked on.

Thanks for fast reply. I've removed all the front left side boards and started to inspect them under magnifying glass. With no obvious visual issues, I've started to check the continuity of the ground with a multimeter. When measured, despite track on PCBA, there was no connectivity between the grounds pins of the jack board (the one with lots of diodes, bridging the power supply board and control indication board. Upon further inspection, one track on PCB was found broken - most likely due to h…

Thanks, Florin

Hi and nice to meet you all!. First of all I would like to thank Andreas for the support in setting up the account. I've recently got a defective SABA 9141, with only known thing that is had a blown fuse. With schematic diagram from internet, I've started the debug. First of all, nothing happened upon power up (Fuse Si651 was blown with wire improvised - stupid DIY.... Upon further inspection, C231 was found defective and replaced. ST6 ribbon cable partially ripped (bad handling for sure). Rewir…
