Tesoro Eldorado on the bench

[paku]

my world still on dark site im sorry ivconic becos u cant see that hahaha

[ivconic]

Wait!! I can see! I can see now! Miracle happened!
...
After numerous clicks on "Reload" button in my browser all of the sudden picture appeared!?
I don't know what was the problem; but i am sure it's about this new forum script! ( ooooooooahahahahahahahahahah!)
It's Carl again! I knew it!
...
Ok, now back to business...

I see now, WELL DONE! It is working just as expected!

Now all you have to do is to carefully apply some epoxy filler.

Be patient and try not to spoil the coil balance!


P.S.

Excuse me for joking!

[ivconic]

Well... i see whole gang of "Black Panthers" standing in a completely dark tunnel, doing nothing... except that the smallest guy is producing occasional high pitched farts !
I suppose the rest of guys are not quite happy! Though it's hard to tell due absolute dark...
...
Now seriously; i can't see a thing!? Am i gone blind or you forgot to remove shutter cover?!

what is replacement for BF245 ?

[paku]

Yes

ok thanks

hi can i replace the Transistor BC337 with BC547

Yes

[paku]

in this picture what is the value for the transistor

[6666]

could you tell me which is the orientation of the 3 transistors - BC327
and BC337?

try this, pictorial view

Hi Maurizio!

I suggest you to remove al opamp and check the voltage present in any socket.
In every pin 4 you must have a negative voltage of about 6,4V and in every pin 8 a positive voltage of 8V.
This is true for all opamp with the exception relative to LM308. In this case you must check pin 7 instead of pin 8.

Can be the transistor warm up for a short circuit.
Please, check capacitor and diode polarity.

Best regards,
MaverickITA

Hello, my name is Maurizio from Rome, Italy, I wanted to ask you of the forum, I have built a treasure MD eldorado, when it does not work always sounds in both metals in all discrimination, and warms up the pnp transistor BC327 in push-pull you located close to the CD4024, I checked all the solder connections but nothing, it always sounds. Thank you for your response.

How to about last bench today?

I meant in the circuit but thanks
