Les puts a bead tant in that position now from what I've seen on his site.
What do you know, I have 3 in original farnell packaging, 10uf 25v, yours for postage cost.
The pictures I see show a SAL (BC128) ?Les puts a bead tant in that position now from what I've seen on his site.
Looking on Facebook I have seen a recent photo and it had a bead tant in there.Over the years I have seen various caps in Les builds including different values,don't think its that critical personally tried all sorts and makes very little difference.
Further to above look at the M180_300 thread on FB that looks like a bead tant to me.
Teddy Pardo used blue bead tantalum caps on a pair of NCC200 several years ago: https://www.pinkfishmedia.net/forum/threads/regulating-ncc200-front-end-and-other-tips.20798/I agree with you. The last production of NCC220, shown on FB, has a yellow bead tantalum fitted on.
Hi Luca
just found some
im not planning on building another ncc amp already built 3
2x used 68uf 2x used 1k 0.1%
2 nos 100uf 30v wet tants
the wet tants and resistors are for the feedback position
tants cost me £20 each from America
but still a lot cheaper than RS..
all tested with Atlas ESR70 the results
99.44 uf 0.37r esr
100.3 uf 0.36r esr
67.08 0.08r esr
65.09uf 0.09r esr
how does £25 posted sound

It's not critical I have 33uF axial tants in there Naim used 47uF beads I think,Les uses beads now check of the latest post in the Qudos thread.I bought a pack of these off that ebay seller and they all measure in the region of 86uF.
I haven`t done any voltage tests on them but was interested how much of a problem the difference in uF value would make to the circuit.
I also wondered about alternative Tant cap sizes/types, having considered a 68uF 6.3v here:- https://www.mouser.co.uk/ProductDetail/581-TAP686K006GSB is this a viable alternative.
Has anyone got details of a replacement part they have used in this C11 position or is it not massively critical.
Thanks.
