For auction we have 4 Vintage Sylvania 6BQ5 EL84 power tubes

Japan production tubes which are very well made and sound great

These tubes are New Old Stock New In Box

Same production run (RC)

Tubes were tested on our Jackson 648A emissions tester and no shorts or leakage detected

A minimum good testing tube would be 70%

These tested 105 110 110 115

So 4 good solid testing tubes
