I recently bought a JMP MK II super lead that Marshall had just serviced and it has the original Mullard power section and one preamp valve so I just wanted to check the sort of ball park value if I were to Ebay them (I love original winged C EL34's so chances are I could sell these, buy some winged C's and still be in profit. I also have a load of NOS preamp tubes including Mullard which in the pre section have never done much for me so I could happily flog the preamp tube on as well)?
The EL34 quad don't have the Mullard logo on them but appear to be identical to these which Watford Valves were selling for LOADS OF MONEY recently until they ran out of stock
I've taken a few pics as well of the EL34's and also the one ECC83
The code on the back of the EL34's is XF4 B7 J1 so I assume this is one made in Blackburn.
The code on the back of the ECC83 looks like 163 B7 03
Thoughts chaps?

The EL34's are XF4 which were that last version made by Mullard. They sound fine to me but tend to be worth less than the earlier XF2's The code dates that valve to 1977.
The ECC83 is a last generation I63 and dates to 1977 also.
Value wise they are worth much more if you have test results for them. Otherwise probably around £20 for the ECC83's and £30 for the EL34's
