Wow Mitch I'm glad your Amperexes are working great because I ended up checking for some last week (tube rolling's enticing) and got a decent deal at Ebay for a pair of NOS US Jan white label Amperex 7308 (from 1966). Can't wait 'till they arrive. I hope they're similar to the 6922 white pq's as I also like the rich /full sound. My Zoe's owner's manual states the unit is originally furnished with 12AU7, which I find also works well. Have you found the ideal tubes for your Lector cdp? Lector's upstream gear are obviously giant killers. I wonder how their power amps sound like. I'd love to get my hands on their phono stage, which apparently costs more than the ZOE...
Best small signal tube for a preamp?
Is there inherently a "best" small signal tube for use in a preamp? Assuming all other things are equal-which of course they never are.
Choices are 6922/12AT7/12AU7/6BK7/6BZ7/12BH7/6H30II (and varients to the listed tubes - e.g. E88CC for 6922, etc.).
The reason for my question is that I am auditioning the Lector Zoe, which can use all of the above tubes by way of its SATC ( autiomatic tube adaptation) circuit and user switchable 6V/12V plate voltage.
I am interested in your reason, which might have to do with inherent sonic characteristics, predisposition for problems such as noise or microphonics, or availability and economy of NOS tubes being better for one tube type over the others. All responses are welcome, and in return I will let you know the results of my listening with the different tubes that I try.
