Yes different tubes do lot change , I 'm using now all NOS 6H30P-DR and the NOS TUNGSOL 6550 black plate.(also in CD7)
If you would like to swap the Russian 6H , there is now in Holland ( Europe ) available ECC 903 NOS Telefunken, they made a special tubefoot which bears two tubes , which makes
a double triode.No other parts to change , just replace the 6H tubes.

@ Hansk46

Most interesting re ECC 903 replacement of an 6H30 , I take it we are talking an double adapter socket that plugs directly into the 9 pin socket that would house the single 6H ?

I would be grateful for any further information regarding where such a socket is available for purchase ?

Yes,please let us know how 8 telefunkens sound.Awesome I'm guessing.

Hello forum members, I can give you the side :
www.triplemaudioshop.nl , take the heading componenten , at this page take the heading buizen = tubes ,at this page take the search in the right upper corner and write down
6H30P-DR , you will see a picture of the double triode ECC903 , take the artikelgegevens , there is a explanation , in Dutch , but if you send an Email in English no problem.People who have done this expensive exchange are very happy with the result.BTW ,I don't work for this company, but have let done major upgrades in my ARC stuff.

Thankyou,for the info on the telefunkens,it is very interesting, I think all up they may cost twice as much as the 6h30 dr.mmm maybe not this time.Ill give the dr s a go next.I read some have tried just 2,in the mix,Ive done that before with 6dj8 and 6922 on a different pre with good results.A matched quad would be better I think
