    Hi up for consideration is one ECC33 Mullard , used tube Tested at 6.4 and 6.9 its condition suggests it has not done massive hours and 9ma is regarded as 100% emission It may seem the mutual conductance rates it in the 6+ but the signal (audio) output is quite good The code is unreadable as the yellow print seems to be masking it it has been tested in audio and seems quiet and not microphonic . what you are buying is one tube , thanks for looking. If there is a particular tube you are trying to obtain then send me a message and i will see if i have it .....there are so many tubes to cover that listing can be quite a job to keep up with..... Please note that I can send parcels through budget postage that can save you some cash however ebay will not cover you if the parcel is lost .....Australian economy post does register the item and issues a registration number but does not issue tracking with it .....please send me a message regarding this prior to checkout if you wish to do this. If you choose economy post then YOU become responsible if the parcel is lost and no refunds will be sent for non collection..

They then branded British made Mullard tubes with their own Philips logo. The British Mullard engineers etched factory codes into the glass of their British made valves,so they knew the difference. *Pope, Valvo, Adzam, Mazda, Amperex, Bugle Boy, Mullard, Miniwatt Dario, and Radiotechnique were all names owned by Philips Holland in the 1950/1960s. The respective names typically referred to factories. For instance, Mullard operated in England. All of these factories may at one time or another produced tubes with various other names attached. Which is why we see Amperex and Mullard tubes made in Holland or Philips branded tubes made in England. Factory codes etched onto the glass or underneath the base of the tube help us to figure this one out.
