That YK is a date code; Oct. 67 like the stamp on the box, I think. DA indicates Mullard manufacture at Blackburn. The tube is unbranded. The British Services were not interested in brands, just the produce. [http://www.tubecollector.org/cv-valves.htm]
You know your stuff =)

When testing ECC32s, which tube type should I use for the settings? My B&K doesn't have setting for ECC32s. I know the heater is 6, but what about the senstivity to check the gm.post #94 of 1026/15/12 at 12:11pmpost #95 of 1026/15/12 at 2:00pmThread Starter
David some B&K circuits cannot measure a 6SN7 properly.
They use 19mA, whereas the proper current is 9mA.
What that means is they undervalue the 6SN7.
So if a B&K shows a good reading for a 6SN7 you can be rest assured it's excellent.
For the ECC32 I would expect a 70% of a 6SN7 value to mean a NOS tube.post #96 of 1026/15/12 at 2:09pmpost #97 of 1026/16/12 at 11:01amThread Starterpost #98 of 1026/16/12 at 12:27pmpost #99 of 1026/16/12 at 2:14pmThread Starterpost #100 of 1026/16/12 at 4:51pmpost #101 of 1026/17/12 at 1:52amThread Starter
