ARTEC 225D

[Zatizati]

Hello.
I live in France and I have just bought an Artec 225D amp. This one is still in its juice ....
I would really like you to help me make an initial diagnosis ... Could you provide me with an amplifier manual if you have one (even in PDF) .... I am interested. I did not understand all the subtleties of the buttons and I do not understand how and where to connect my cables for the speakers and what are all the inputs and outputs at the back of the unit...
I don’t really know if the tubes feeting the amp are the good one.
I feel like they’re not the right values.
I opened the tube and i cleaned it. But after i didn't remenber where to fix the tubes.
There are 11 tubes: 2 x ECC82; 3 X ECC83; 2 x EF86; 4 x 5881
I don't know where to place them. Couls you help me i, send amp pictures.
Thank you so much for your help.... All documentation will be precious to me ... I have to take care of this little baby of almost 25 kg...
Please I need help!

Sorry for my bad english

Do you have a multimeter? On most amplifiers like yours, ECC82 and ECC83 tube sockets have pin 4 and 5 tied togheter, while EF86 does not have this connection. This will enable you to find the EF86 sockets. ECC82 are almost always near the big output tubes. I see on your picture that there are exposed high voltage wires on the top of the chassis. Be careful when the amplifier is turned on and the cover is not installed.

Normally EF86 are in the phono stage, one per channel
The 83 can be on the line stage and first stage of amp. The 82 are for driving the power tubes.
I think Ketje is right. And pcan is right
