Svetlana EF86 vs High- Performance Audio Small- Signal Pentode he Svetlana EF86 is a glass envelope miniature pentode intended for high- vs quality audio preamplifier service. It is very similar electrically to datasheet vs the octal base EF37A and the Rimlock base EF40. Any cheaper good ones out there? pdfbytes) EF86 Mazda- Belvu p EF86.
Anybody think is a same tube? I see spec it is same. to Ron kremer, you say EF40 can use same EF86, it really because I: see many tube i my tube. Mullard describe the EF40 as a voltage amplifying pentode, primarily intended for use in high gain RC coupled AF voltage amplifier stages.
