9141tc US Ausführung

Well, you first have to refurbish the power amp circuits, and then the drivers. You can follow the systematic advice from the 9241, as the circuit is the same, only the total voltage is lower in the 9141.

Since these circuits are a bit critical, I would advise to check all parts, and if in doubt, replace them. If it helps you, I could also send a full set (two drivers, two power amp boards) that are fully done, if you send the faulty ones to me. If you are interested, send me a private message.

Cheers, Michael

p.s.: Also, be advised to check all solder points. I'm working on a 9141 TC myself right now, and this copy has MANY bad solder points ... really many ...

Hello:

Great, thank you very much for your advice.

I didn't find a place to send pictures in the private letter, so I had to send pictures here. Please see the private letter for others.

Hello kugel balu，

Great, thank you very much for your advice.
1/I need 2 sets of amplifier boards 14 #+2 sets of driver boards 13 #,
2/I also need a complete set of channel selection switches, including the knobs. My one has failed and broken,
3/saba 9241 Three knobs (see figure).

OK -- a 9241, not 9141 ... no difference for the drivers, but an important difference for the power amps. They need to be equipped with type "C" transistors to be on the safe side, as the voltage is higher. I have to see whether I have a set with those ready ...

I do not have a spare switch, and also no spare knobs any more ... all gone ...

Or is only the last question concerning the 9241 ?

Hello,

Thank you very much. I'm a 9141 driver and amplifier board, and the 9241 is also OK. I'll change it when I come back. I'll see what you have.

I definitely have a full set of drivers and power amp boards for the 9141 ready. They work with the lower supply voltage, so the BD 245/246 B are fine. More when I'm back, on Sunday or so ...

Michael

I am waiting for your good news, thank you again.

Sorry -- it got sidetracked ... please send me a PN. Also tell me which modules you need, I think I have most of them here.

Michael

Hello, my email:



Thanks again.

Well, send me a PN, and maybe introduce yourself first ... I do not even know your name !
