Our users rate Reverb
Today I bring you this exclusive vintage lot of 4 Tungsram EF86 tubes tested on Kyoritsu. Low-noise, high-fidelity pentodes with codes 3Y, YZ, M4, BD. Ideal for restoring classic amplifiers.
We know that reliability is key in refurbished components. That's why these four Tungsram EF86 tubes have been tested for emissions and short circuits using a vintage Kyoritsu tube tester, with positive results for operability. Although they come from different manufacturing batches (codes identified below), their electrical performance makes them compatible to work together.
When you purchase this product, you will receive exactly the 4 Tungsram EF86 tubes shown in the photographs, identified by the following batch codes printed on the glass: 3Y, YZ, M4, BD. Tungsram-branded cardboard boxes are included (note: we cannot certify that the boxes are the original boxes these specific tubes came in, but they protect the unit perfectly).
