EF86

By Sweetwater on May 26, 2015

A preamp tube famously used in 1950s preamp circuits by Vox. Unlike the more popular 12AX7, which is a twin-triode tube, the EF86 is a pentode tube. This characteristic means that it has more gain than each half of a 12AX7, although a circuit that cascades both sides of a 12AX7 can generate more total gain. In general, the EF86 has a smoother, less glassy tone than a 12AX7.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off.
