Bah-bwana,

it's the light, the dig.cam. and the byte size limitation that's to blame for most of the difference. (plus me is very sheety camera man)

My experience with a lot of Japanese device types is that the quality of the printing varies greatly.
(some of the devices on this piccy are probably older than you will still have teeth, under a magnafying glass the printing looks much the same + all measure as jfets.)

Understood.

I'm very sensitive not to see any fake as I was cheated more than once.
Sometime, I feel that I should have installed the automatic vapor pressure
relief valve on the top of my boiling head.

UPDATED COOK BOOK

Looking into the Shunty's schematic (http://www.diyaudio.com/forums/showthread.php?postid=1335499#post1335499), there are different values for C9 and C9A, as well as for C10 and C10A.
:whazzat:

It's obvious that should be the same in pair and according to BOM, should be like this:

C9, C9A = 10uF
C10, C10A = 100uF

Correct?


quoting my friend spavleski again .........

anyway : lookie lookie here :
