es44: Q1,Q4 are upside down on your schematic. Also C2 needs reverse polarity.

Yes, C2 and C1 is facing the same direction.

Ah, i see where you're getting at... Yes, it's the wrong way around. (blushing)

Yes SB was for Steve Bench.

Could you please give your opinion about how your phono sounds on complex music passages? (rock, cuban big bands,...)

I have constructed Pacific (original + most variations published on net) and when things got complicated didn't sound any good.

I don't know I never did the Pacific, and this one is developed without that in mind with some quite different basic decisions. In complex passages it never gave me any concern. There are also people in this thread that built mine with experience in listening and good systems that did not say anything about such problems. You should check it out yourself I guess and see. The shunt PSU sounds solid and smooth and big non the less, and that should help.

Hi salas,

Thanks for the reply.

The schematic for the the led shunt is as post 336 ?

If yes, I think that I need your help to bring it to 36V.
Also is there any more readily available substitute for the k170s. I don't have so many of them and it seems you use them everywhere...

My line stage's input is at 47K do you think I need the buffer ?

I used the Linear Systems LSK170, but I also found some 2SK170 on eBay.

Here you are. Don't go over 43VDC in, the left hand 2SK170 has 38V across already. 40V is its max.

No, you will not really need a buffer. If you notice some strain, add one. Jonners added one and said it was transparent. He has OB speakers and he is experienced.
