TUNGSRAM EL84 / 6BQ5 Hungary

 

 

TUNGSRAM EL84 / 6BQ5 Hungary
A power pentode tube. And, another excellent product from Tungsram. These are from 1960 and 70's. The VTV Magazine Issue 8 finds this tube  "harmonically rich  with a nice hard-rock sound" for guitar amps. Their review for hi-fi amps says :  "It was actually a great performer. This EL84 had lots of air and was very 3-dimensional sounding. It also had lots of punch and great tonal balance. The Tungsram EL84 was very enjoyable and musically involving."

Please note that the intensive silvery metallic deposit/flashing on the inside of the glass, around the dual plate holes are not burn marks, but these are magnesium fall-outs originated during manufacturing. This is something peculiar to some Tungsram tubes including EL84's. Existence and form of the flasing vary from tube to tube. A part of the stock are labeled for RSD and Philips.
