Tube question

[vintage 5.0]

I put a new set of 4 6550 tubes in my Jolida. My question is do tubes ever sound diffrent after a few hours of burn in time. Is there such a thing as that.

Possibly a little. Lengh of time needed to settle depending somewhat on the tube type and brand. What seems to matter more is the settling of the capacitors at the new quiescent voltages that the tubes create.

No, burn-in isn't real.

Hello

I think part of "burn in" is your ears getting used to things sounding a little different. The rest is an endless debate.

They can. I've noticed it, and I generally regard such things as nonsensical BS. Maybe its my ears breaking in, or maybe its the tubes, but something seems to change IMO.

Thanks I have heard that but was not sure if it was real.
