Dear community,

thank you to be a part of it here.

I am relatively new to the Shindo brand and own an old Minbrison and new to me a Cortese F2a. At he end, there are playing some Lockwood Major fitted with Tannoy MG 15".

I bought the cortese with some tubes they are not the original equipement. Does anybody know, apart from the Siemens F2a, which tubes should be fitted originally ?

Thanks in advance,

Rüdiger
 
My Cortese has the original equipment Siemens F2a as it was purchased new from an authorized dealer. I believe they are the only tubes used for original equipment. Almost impossible to find in the aftermarket.
 
Dale, thank you. I wanted to know about the other 4 Tubes. One is the rectifier, two in the front at the right side, the driving tubes and one in the middle, in front of the rectifier. I have no info what was the original setting with it.
Regards, Rüdiger
 
New Cortese employs two ECL82 input and driver tubes instead of 6AW8A. And 5U4G rectifier.
