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,
Paul S
