Merlin,
am very interested in your build, can't wait to here how it sounds. What cartridge are you using?

@SGregory,
NSurely the balanced RIAA will finished in a couple of days, now I'm using the Denon DL103R with good success, I am planning to buy a Transfiguration or a Shelter to do the definitive jump to heaven.

Minimum order 5 pieces at 10€90 each, anybody interested to share the order?
Merlin,
here is another candidate (maybe?)
Digi-Key - 490-1957-ND (Manufacturer - TZ03R121F169B00)
It's good to have some small fixed value caps on hand when you do that.

Hey psgr,
I am glad to hear you again, that's you propose it's ceramic but if you use only to finetuning the RIAA can be OK if when you know the exact value replace for fixed better caps.
Do you have photos of your RIAA & regs.?
Cheers
Felipe
Merlin,
I have not started yet, I'm missing a few parts. Now that it started getting cold and I will be spending more time indoors I will complete the Riaa.
About those variable caps your working range is 180 degrees, maybe it's better if you can find something with a little larger capacitance, it might be easier to work with.

Hey, whats up?🙂
You got a true MM cart if I recall correctly? You must make the #4945 first on the left with R2 100R for 38dB and no clipping as I describe there.

Giasou Salas,
I saw that the other day, I will.
I have a MM cart of unknown brand, since there is no label on it, I'm not sure what is the output !!!
I have not heard from you for a while, did you get version a3 of the document?

Just looked by email search and its there indeed. I don't remember reading it though. Must have skipped it. Will read it and let you know.
Make the R2=100R MM, its most possibly a normal MM cart.
I have been experimenting with decoupling caps in my 48dB riaa and I am amazed by the results.... these caps influence tone (I knew that) but they also influence noise...
After replacing the 330u decoupling caps by 680u BG N, the noise went down to the point where I can no longer hear it..... Is it possible or is there any other reason ?

If the caps have less ESR, this could be it. Caps with larger ESR produce larger noise and filter out less noise.
I don't know how dielectrics or electrolytes factor in here.

In the RC filters? Bigger caps normally have less ESR spec. The 330uF is enough, must be the impedance.
330uF was also BG with same voltage?
BG are my prefered lytic caps, I love them, are far better that any cap, it is a shame that is stopped making.
Also are killer in PSU.
Welcome to the BG no noise😀
Ricardo you you have two possibilities depending what are you looking for:
1-Less noise can reached paralleling two BG N "L-Cancelling Pairs" so + one cap to - other cap, look for at the Michael Percy pdf. web
2-N series are very very low noise so very very transparents, if you like more body I will try BG standard 470uF 160V you will be near near heaven🙂
Let me know?
Balanced ready to adjust, 1st attempt only with two old regs. V1.0 RS
