test results valve 1: 1.70 mA / 2.0 mA/V test results valve 2: 1.50 mA / 2.0 mA/V
1.70 mA / 2.0 mA/V 1.55 mA / 1.9 mA/V
book values are 1.20mA / 1.6mA/V
the tubes have also been tested in my Woodside preamp, sounding sublime
please note that although the valves have Tungsram labels on them the factory date codes are both B6K
B6K indicates Blackburn Mullard factory Oct 1956
and the construction of these valves' getters are unique to Mullard mC1 ECC83 type valves
Incidently it is the copper anode rods that give the Mullards that warmer English sound, still detailed though, with a great soundstage
.
Please note - I usually re-list my listings every 2 weeks. Sometimes
when the listing ends ebay shows it as no longer available, so it is
worth checking if I have just re-listed it..
