E88CC recommendations?

[Simon]

Have a look here:
6n23p
It seems the measured 6N23P is not an exact substitute for ECC88.

In circuits designed with GlassWare TubeCAD for the ECC88, an actual 6N1P measures the same...

Doesn't surprise me - I think I'll keep my fingers crossed and get a couple of 6N1P -VI's and have a play around. I don't expect that the Audion's transformer will have too difficult a time of it - isn't hi-fi all about over-speccing circuits?

Asking for tube recomandations is like asking what new car to buy as it's really a matter of how it sounds in your total system and of course personal taste.
I had the Audion Silver Night phono (a fist run)they used the pre amp Silver Night chassis back then.
The 6922's I liked best are these (hands down) that includes NOS tubes like Mullard,Phillips,RCA and Tungsram ect...
It is the only tube I would use in your phono stage, because they are not monophonic, they have no back ground noise and the presentation is stunning.
They are new and sold in closely matched sets,and you won't be disappointed.

because they are not monophonic

What is "monophonic"?

At the risking starting an "oh yes it is, no it isn't debate" please bear in mind the 61NP is not the same as the ECC88, you can often use them interchange-ably but they are not the same. I believe the 6N23P is closer but I don't have any experience with them.

I only say this so that anyone rolling tubes is aware of the differences and the possibility of, however remote, of damage. Please study the data sheets for yourselves and make up your own minds that the best advice I can give.

What is "monophonic"?

Some tubes are prone to making noise at the slightest vibration from even a little bass. Some can be so bad just touching the volume knob can be heard.

Ah, ok, microphonic, that I know... Too well...
