I have 3 old Philips MiniWatt / Mullard EL34 tubes that just got tested. These are very good and known tubes for their high build quality and superior sound.
The tubes:
2x xf2 b3f4 OO getter (-> BlackBurn UK '60 - '68, dark brown -base) MATCHED PAIR -> GM= 8,4mA/V & tube 1: Ia = 60,8mA | tube 2: 61,4mA
1x xf2 b3f4 OO getter (-> BlackBurn UK '60 - '68, dark brown -base) GM= 8,7mA/v & Ia = 65mA
The Philips MiniWatt labeling on the matched pair is still very nice. On the extra tube it has gone. But the tube code is still readable.
These tubes are pretty valueable, especially the older ones like these XF2 Mullard tubes. They sound really good with a lot of detail and very nice mids.
I list the thirt tube separately because it is only a close match to the other 2, not a perfect one.
Price for the matched pair: 180 €| bidding starts at 120 €
Price for the separate tube: 80 € | bidding starts at 50 €
For shipping costs : ask me, I will look them up for your location.
