I received a pair of Amperex 6688A. These are supposed to be equivalent to the E180F.
I put them in place of the Siemens D3a.
And in my circuit they are absolutely lifeless. So are they bad tubes? I don’t think so. Are they not really equivalent to the E180f. Maybe, maybe not.
What I think is we should be reminded that how a tube sounds must taken in the context of the circuit in which it is used.

I think this is something we forget. It is easy to read that this ‘tube’ sounds great and all the others are shit. But if change the circuit, a tube type that you may have previously written off, might be just the ticket…John
