Post Subject: The new life of Rohde & Schwarz decoder.Posted by Romy the Cat on: 8/13/2008

What an incredibly cool result!!! I retrofitted the Rohde & Schwarz decoder with a few changes and it throw a very very very nice sound, in fact even better then I predicated. The Decoder has a SS single-end out stage (not PP) with a high-heated transistor driving output transformer. I decided at this point to drop the OPT and use capacitor coupling. I ordered 12 Wet Tantalum caps of different values and replaced the original dry capacitors everywhere in the decoder’s signal path. I replaced the large 1000uF cap in PS’s with the contemporary Philips 90V, 8000uF – the diodes it looks like handle the serge… The result is extremely nice  - the Wet Tantalum is looks  like truly indispensable in Schwarzes.

I hate to admit it but it look like the Tantalumed Schwarz decoder has… even more profound bass then my king of the kings - the TU-1X. When I begin to discover it I was purring…  There are a few other very interesting aspect… I would like to look at them further what the unit will burn a little but the initial sentiments are very exuberant.
