Default SoundStream D100II

Trying to fix a non-working D100II.

I see a number of posts about schematics, but have been unable to find a working link for download.

Does anyone have them, and willing to share?

THANKS!

In the meantime, maybe I have a common problem? Power comes on, transistors get warm, but no output. Scoping out the final transistors, input level looks the same as output (very low). Power Supply seems to be fine, (32V both + and -).

.. and, I did pull one of the final transistors for a diode test, it tested OK.

Prompt Service! I see it says "D-200". Is the later "II" style the same? or similar enough?

thanks again.

Thanks again, much appreciated!!

I see the TIP142/147 is a darlington. Is there an accurate way to test them with a multimeter?

Considering the "output" is exactly the same as the input (same amplitude AC wave, but not riding on a DC voltage), I think they are probably shot..

Hmm.. Most of the replacements are TO-220 packages, mine look bigger.. Maybe TO-247??

Mouser has them listed, About $12 shipped to me for all 4. Probably worth the gamble. Going to sleep on it..

They have been offering them in TO-220 package's since ~ 8 years back. SoundStream used some of them in a few Rubicon models they had.

I have ~ 100 pieces < both N and P > of original NOS TO-218 1992 date code parts I bought long ago when these D series amps were still very popular. You might want to try and find the original package parts so the leads mount properly and the case thickness is not a issue since they rely on the PCB to clamp them down to the sink surface <I.E. the case height/thickness differences might cause interference fit issues > I have not ever modded one of these older D series amp to newer packages but its a possibility that the different cases may cause problems. The device internally should be the same, but its foot print will be smaller and its lead spacing in not the same, along with overall case dimensions being different. Just some food for though, and if you can't find them P.M. me, my stock runeth over...lol

Any luck with the schematics for the D100 II? I notice my amplifier has a 3067 6 pin DIP.. I think that is a 2SC3067, dual transistor package? I don't see such a thing on the regular D200 schematics.

Doing a ohm/diode test on the 3067 makes me think it is good too..
