5751 Sylvania USA
Rare Triple mica, strong, perfectly balanced triodes
Please note: even if a 5751 can be used instead of a 12Ax7,
to have a correct measurement, a 5751 cannot be tested like a 12AX7.
The nominal characteristics are different, a lot of confusion on this subject.
please see photos and Mazda datasheet.
