Original Telefunken CF7 tube
Pentode
Vf - 13V If - 0,2mA
13H1 TCF7 UF7 SP13 UHP20 UHP52 VCF7 S1324 13U11
The tube seem to be unused, or slightly tested with the great results:
Ia = 4mA (130%)
where 100% for the new tube is 3mA
the tube is in a great technical shape.
Europe side contact base P (P8A), with top contact
you will get the tube you can see at the pictures
I always send the tubes by priority registered mail with tracking number within hours after receiving payment
