I studied your homepage allready, Choky🙂 Very nice homepage, and quite skilled too🙂 NCC oilcaps you say?? Hmmm! I might consider something like that, if you can convince me they sound any better?🙂

hehe-name of the game is funnnnnnnn
Just right, Choky😉 As a matter of fact, I did bid on some oilcaps on Ebay, but didny get them
Maybe good so? What should I look for with those particular caps??Steen🙂
best way is to buy some new ones-like Jensen or Audio Note (UK,not Japan
) ,just because every old cap is sort of lottery.......not if you scavenge them,like me 
maybe is better that someone outbid you; when you want to buy (any) cap-look for tested on leak and ESR
I just reinvented boiled water for ya hehe
I like oilers ,(and Iron,too) especially with sand parts,just because I dont run away from that sort of silky sound
anyway-I like sound with PIO and motor caps ; each one in adequate position

As a matter of fact, I really look forward to hear the NS10 Megaclone with the Pearl. It takes some rebuilding, as my Pearl is somehow attached to my BosoZ🙂 Take a look here😉 :
http://www.diyaudio.com/forums/showthread.php?postid=504780#post504780 It just might be a perfect combination, dont you think??

Both companies are Danish😀 I might get some for cheap then?😉
looks messy 😉
why rebuilding-just trow out signal from Pearl and listen; if you like what you hear-your BOSOZ will have one more line input,and your tower few more gadgets on it ........
besides-phono stage just begs for dedicated box......in my case it will be booooooox or boom box 😱

little OT-but what is OT on Pass board 😉
psssssssssssstttt (on Serbian )
or
shhhhhhhhhh (on English ?)
is it still secret what sort of Jfet is in Aleph J?
or I'm just unable to see that on Diyaudio.......

Choky, I am sure NP used those Lovoltech Jfets🙂 I will look into this, though😉 I want to make two Aleph's with Jfet inputs!!!! Monoblocks ofcourse🙂 I will just wait till NP release the Service manual😎

Steen,
That Megaclone is looking just wonderful with those shunt regs. I’m sure it will sound wonders with your beautiful Pearl.😎
Yep, its that time again😀 I just wish that Santa had dropped the version suffix also🙂 GR, BL or V?

what's happenin' with Mega Clone?
ps-seems that Choky must take potatoes from fire in last time
hehe,not only that I'm biggest EMT fan in the world ,seems that I'm biggest greenhorn hanged on NP's neck , at least this days.....
"Master,where is NS10 schm..........
which values those resistors have.......
what is da Fet in J .....
can I make Aleph with BD139 in output ....."
etc
meet Choky......clown in the Village....
but who cares ,when we have that good lookin' Santa....

I finished the second edition of this preamp. It surprise me how good it sounds. It has a very crisp and clear sound, yet very, very pleasant to listen to. Not excactly what you are used to with these small transistor linestages. Parts used are Panasonic FC's for electrolytics, all filmcaps are Rifa PHE426 except for the output cap which is a 22uF MKP-roll, its the big black thing hovering over the boards. The feedback B2B cap is bypassed with a 470nF Rifa. Transistors are MPSA18 and the pnp device is a BC560C. Resistors if you care are BC metalfilm's. The psu is a 50VA 2x25v potted donut, connected to Choky's "shunt reg" supply.
Its described a bit earlier in this thread. I used small schottky's for the rectifier and good quality electrolytics for the smoothing. With the better parts and a better supply, its like the curtain went up🙂 This little preamp actually sounds very good. I won't rebuild this one right away; it stays in the main system for a while.
(Except for a slight trace of buzz that I have to hunt down. I can hear it when I stick my ear to the speaker
)
To Choky: (and others who find it useful, ofcourse)
Current draw is 10ma on both the pos rail and the neg rail, so the current draw per channel is 20ma, as suggested earlier.
Here is, as usual, a piccy, of that little wonder.
Hope some of you find this information useful🙂

Wow Steenoe! Excellent preamp. I kinda feel like a proud uncle or something seeing those PCBs in there. I will update the layout per your suggestions soon. 🙂 Happy listening!

Very nice indeed Steen, as usual, excellent work.🙂 🙂 😎
Most probably the buzz is coming from the power supply. Just to make a test, try bypassing the reference diodes (zeners) with a 0.22u MKP (if you are not using that already) and see what happens.
How about bass performance?
