EI Mullard EL84 6BQ5 Yugoslavia Vintage 1968 Vacuum Tubes Vox Guitar Amplifier
Quad of EI Mullard EL84 6BQ5 Made in Yugoslavia Vintage 1968 Vacuum Tubes. Test good on my tester. I removed from a working Vox AC30 guitar amp I owned a number of years ago. Date codes appear to be KM4 Q(not actually a Q but a similar looking character which represents Yugoslavia) 81 which indicates Nis, Yugoslavia 1968.
