Post Subject: Cartridge loading and tuning for ribbonsPosted by Paul S on: 5/6/2007
Good advice, to be sure.
I have chosen the most "neutral", "tape-like" MC I have found, but of course it remains a phono cartridge/transducer... Meanwhile, I just checked VTF on a hunch and was annoyed to find that at some point I had left a set-screw un-cinched and the VTF was running light. Re-setting this to max worked wonders, as you might expect. (what a dope...)
Phono stage is new (an Arthur Loesch variant, but not Thorsten's), and there remains work to be done, mostly getting overall balance right. I will not add a ribbon L-pad until this is done.
Based on previous trials, I have avoided putting resistors on my new ribbons so far. Finding decent caps and coils has been enough of a problem already, since everything comes through so clearly. Maybe a variable inductor... probably hear the wiper... Any ideas?
I was thinking of and dreading futzing with incoming/RIAA cartridge signal, but then I realized that output RC changes alone might do it, and that is simple enough (just time consuming and expensive). Have you tried those Ice Cubes in phono RC out, at ~ 4 uF? The exotic stuff can have extremely "nice" areas but typically some discontinuity. I am so close...
I did not mean to insult you, Romy. The "coated wire" reference was as much for others as for you. Lord knows what people are into these days...
Best rgards,
