ggta & Maousse,
At first I prepare less people love full balance, so made the SE kit more than full balance kit.
Selection kit only in the full balance kit only, not with single end kit.
So need extra prepare for it. many sorry to so late.
5 sets of selection kits test OK. pls remind me your detail address & telephone no.
missing parts too.
I can post tomorow.
thx
thomas
Hi Thomas, I know you're very busy but don't forget me !
If it could be an easier solution for you, just send missing parts to Maousse...

Hi Thomas !
After the inventory 2 boards are missing.
The pic in Post #1333 : 2 boards at the right bottom are missing.
In Xaudiox Post #1681, the 2 boards located at the left bottom, right to the TDA and below selection board (pic n°3).
You could ship them with the new tube buffer PCB.
Regards

tube buffer + power transformer problem
Hello Thomas,
i have a problem with 15 v transformer, i only have 8 volts ; i tried Kooka and Julien connections, and still only 8 volts???
the other transformer (9v) is working perfect.
another thing : some news about tube buffer?
thx a lot in advance!

"hi gomi,
U need waiting for the PCB funish & post together to U or post parts to u first!
if U need post PCB to U later, PCB will free but U need to pay extra postage, if together not need pay anything!
thx
thomas"

Re: tube buffer + power transformer problem
Hi Gomi2,
What is your main power voltage? Kooka's is 230V and Julien's is 110V. You need to wire them according to your main voltage. If yours is 220/230V, have a look at mine.

One thing I do find is the transformer pin can be a bit dirty and not taking solder. Give them a bit of light sanding and it helps.

Re: Re: tube buffer + power transformer problem
Yes, on the primary side you have the same connections in both transformers. But on the secondaries sides you need different connections. Look at what SamL did, that is simple and correct.

transformer pb
hello all,
i am using 220 v main.
one thing is changing for 110 or 220 main : it' s primary connection.
for secondary connection , this is the same thing ; i tried Kooka or sam connection (= julien connection) : always 8 volts.
????
sam connection for secondary : (=Julien connection)
12-19 connected together, and connected to "o" PCB
14 and 17 connected to one "16v" pcb socket
Kooka connection for secondary :
14 and 17 connected to "0" pcb, 12 and 19 connected to one "16v" pcb socket
this is giving the same result with my transformer : 8 volts !
thx a lot!

hi gomi,
pls take photos of the connect method of U in forum,
with PCB pls.
if transformers had problem, I will post one new one to U.
if only half of voltage U get there may connection method was wrong!
OK!
Tung Duong,
your selection kits with two nano pulse trans was RA18748676hk.
thx

Re: transformer image
Hi Gomi,
Can you try measuring again with the 'black' lead on earth from the main.
