Are you looking for the very best tubes for your vacuum tube amplifier? This is the place to start. Check out the following tube reviews for guidance in getting the best possible tone out of your tube gear. A complex mechanical structure, combined with a high gain design, make the EF86 very susceptible to vibration and the resulting microphonics. A triode has three active elements while a pentode has five. Most people know that a 12AX7 is a dual triode, that is, two preamp tubes in one small bottle. The EF86 is a single, very large preamp tube by comparison. The EF86 also has an internal shield structure that is physically tied to pins 2 and 7. There is a lot of precision hardware that is carefully aligned to prevent physical damage or electrical failure. Older tubes from Telefunken and Amperex used to flash metal directly onto the base of the tube between pins 2 and 7. I can only assume this was to reduce the number of physical leads inside the bottle. This tube was designed for radios, tape recorders and home audio. Anything that has low volume or the ability to isolate the tube from vibration. The EF86 made its way into guitar amplifiers because it had a lot of gain and a good track record in quality audio equipment. VOX, with the early AC30 is perhaps the best example. You would have to talk with the original designers, but an EF86 can easily drive a signal through a simple tone control and high-cut filter into the output section. If you take the tremolo and vibrato circuits out of a vintage VOX using an EF86, that is exactly what you will find. Modern amp builders generally do not bother with this tube because it is so hard to find one that will work in a tube combo amplifier. There are a few like Dr. Some things are so good; you are willing to put up with their shortcomings. Hope is not lost, because there are things you can do to make this tube work. There are no substitutes. If your equipment uses the EF86, you have to like it enough to deal with microphonics or get something else.
