I thought I would start a thread to see what others have tried.  I have had mine for a week now and did try some Amperex orange globe tubes but did not think they improved on the stock tubes.

The other set of tubes I did find someone that has nos Russian made ones but not sure if this type of tube has much of a sound charestic that can be improved on.

Thoughts....

Hi,

I have NOS GE/Mullard 6ES8/ECC189 tubes in my PH 9.0.  I like them a lot.  So much so, in fact, that I haven’t been tempted to roll beyond them.

Thanks Drew, it is a very nice phono pre

I'm using Amperex 7308's in mine and love them. I haven't tried the stock tubes.

Looking for additional suggestions for 6922 or equivalent substitutes. Dan, are Russian 6N5P tubes compatible? I have some 1970's NOS 6NP5's in my preamp and they sound very good and balanced.

Try the Amperex 6922, USN, white label with gold pins.
Quite vivid but balanced.
Use them in my Modwright modded Pioneer CD Player.

Hello,

I'm curious about this thread also. I have a new PH 9.0 and am enjoying it.

I've listened for a little while with the supplied tubes. They two 6922 variants are 6H23's, but I'm not sure of the brand.

I've swapped in some Orange Globe Amperex 6DJ8s from the late 60's from Herleen. I felt they did make an improvement.

I've been considering trying others, but I only have the Orange Globe's in my collection, so if anyone has positive experiences with other brands in the 9.0 I'm interested in hearing about it.

Best,

David

I'm using a match pair of Amperex SQ gold pin 6922's. Love the sound.

I tried some of the new Gold Lion Genalex tubes I feel they are a little better than the stock tubes

Same here. I think they are definite improvement. I went for cryo option and use them in my MW 225i with similar improvement in sound. Smoother, quieter and not harsh.

Are you talking about the Gold Lions? Where did you get cryoed ones?

[eduke55]

Got them from Upscale Audio.

I am currently using Siemens ECC88 tubes with O-getters (one tube from 1962 and one from 1963 a few months apart).  The Siemens sound clear, quiet, and very dynamic. 

I also tried Amperex PQ white label 6922 tubes from 1970.  I liked the sound a lot, but preferred the slightly more detailed presentation of the Siemens.

The tubes that sounded the best, but I have held off on using, are Telefunken ECC88 tubes from the 60s with the small print labels.  I bought them NOS and have had them stashed in my collection for years.   

The EH Gold Pins that Dan ships the phono stage with sound very decent for new production tubes.
