Just received some 680uFBGNx35v from Canada. the guys from FedEx asked me more money for the delivery and customs than the already high cost of the caps. And I already had payed for their services in the original invoice. It was my first and maybe my last order from overseas...

But I got a reward in the end... I replaced the 470uF 50v BG Std in the shunt output by one of the red caps and.....

It seems the shunt marries perfectly with the BGNx.... wonderfull powerfull detailed bass and sweet trebble just five minutes after turn on.... imagine what it will be like in two weeks or a month.

Ricardo

PS:
Here is my first draft of the riaa.... Please guive me your comment and advise.... (It will be used for p2p).

It is a very low noise cap.

I noticed an important reduction in noise. That brings out detail. I had the same feeling when I installed the geddon on the TT.... lower noise floor.... much more detail.

PS
When you have time, please comment on the drawing... I must be sure there are now flaws this time.

Post the matching circuit version with matching part numbers also. But I don't think that I will have time to inspect today. This is to make in P2P?

Hello,
I'm collecting the parts for the RIAA but I'm not able to find Q3=BC550BP.
Can you help me? what is BP or can I use something else?
Thanks a lot.
Ciao
Guglielmo

BC560B or BC560C are OK. BP was just the program's silly way to say BC550 BiPolar.
