Tube rolling - Mullard vs Brimar vs JJ

[JonnyCJ]

Dug out some old tubes from a suitcase I had under the stairs and had completely forgotten about.

I have 2 x Mullard Long plates and 2 x Brimar - 1 long plate one normal.

The valves in my Pre 3 and Phono 3 are all JJ's. Question is, am I better off swapping the JJ's over for Mullards or Brimars ? Are the older valves generally better sonically ?

Thanks in advance

Jonny

Hi Jonny, you don't say what the valves you found under the stairs are, your PRE III needs ECC82 & the phono needs ECC83. Is this what you have?. BOB

Sorry Bob - valves are all ECC83's and 12AX7 for the Brimars. Got a single Mullard ECC82 for the Pre so far

Thanks

Jonny

Simples. Roll all the tubes and use the set that sound best.

Agreed - however, I would need another ECC82 and ECC 83 of each make to get a full set and rather than starting with 3 full sets I'd prefer to know which generally sounds the better of the three types and see how I go from there.

You can try the two mullard or the brimer's in the phono in V2 and leave the JJ in V4, you can even try the ECC82 in V4, but do not try the ECC83 / 12AX7 in the PREIII as you will have too much gain, all these valves are the same pinout. BOB

That's great - many thanks Bob
