This offering is for a closely matched pair of Phillips EL84 / 6BQ5 tubes. These are considered one of the very best EL84 variant tubes. They were made in Vienna Austria in 1967. They carry the matching date codes of A711 and series of KM4.

These tubes were tested on my Hickok TV-3B/U tester. It's chart lists the minimum score for a good tube to be 4500. Both of these tubes tested at 9500.These high and closely matched scores make them an excellent pair.

Both of the tubes have paint loss on the labels from smudges. However, there is enough left to identify their model, series, and manufacture dates. 

I do not have the original boxes but have repackaged them in new white boxes with identifying labels.

I warrant the tubes to be as described when you receive them. There is no additional warranty.

Check my feedback. I describe my items accurately, pack safely, and ship quickly.
