12AX7 Tubes what to buy/where to buy

I was talking to my amp tech about valve availability recently. 

 

He doesn't rate the Chinese replacements but availability of the superior Russian valves has stopped due to the conflict. 

 

You may need to hope that back stock is  available from places like Bass Direct.

i've always bought from Watford Valves, just replaced all the valves in my little Laney LC15 guitar amp, went for the Harma Retro and they sound pretty good, close to the description on the website.

 

on a previous amp i went for the Cryo treated ones, no idea if they were better than the standard but the amp sounded very nice afterwards.

I've always used Watford Valves too and know (and really like) the Harma STR's. I've not had a chance to roll the Retros yet, but I will when I have a valve pre again! Derek (I think is the man behind the brand) has always been helpful.

I really like the Electro Harmonix 12AX7EH tube.

 

Use it in all my tube units.

 

The cheap Chinese ones that most cheaper tube units comes with from stock tends to sound thin, shrill and fizzy.

 

Same here, I have them in my 1000w Terror amp and they are spot on.

These tubes are (were, since the Ukrainian war) made in Russia at the EHX facility owned by (the American) Mike Matthews (New Sensor) since 1998 and some brands are simply resurrected names:

EH (Gold),

Electro-Harmonix,

Genalex Gold Lion,

Mullard,

Sovtek,

Svetlana,

Tung-Sol.

 

There are the two alternatives to these EHX branded tubes:

JJ, formerly Tesla (Slovakia),

Western Electric (USA).

 

Then there are these very expensive boutique brands:

Elrog (Germany),

Emission Labs (Czech Republic),

KR Audio (Czech Republic),

Sophia Electric (USA or China),

Takatsuki (Japan).

 

Then come the Chinese brands made by Shuguang, now more specialised in the very lucrative audiophile market:

Golden Dragon,

Grant Fidelity,

Lenlai,

Penta,

Primaluna,

Psvane (PS Vane),

Ruby,

Shuguang,
Sino,

TJ Fullmusic,

Valve Art.
 

This is to date all the real brands I know still available today (and I'm deeply sure there are no others), the rest being rebadged Chinese tubes, sorry for those pretending the opposite, even if there are stories about new facilities in China that, when further inquiring, are impossible to locate or suddenly destroyed...

i've just realised that since my last post in this thread I have bought and re-valved a Mk 1 Orange terror bass!

 

I went with these NOS Philips valves from Langrex, Linky  I went for the 12AT7 as they are lower gain (60 vs 100 for the 12AX7 I think) and the price with postage etc was very good compared to other places and the WA spec ones are supposedly military grade.

 

the amp is now much more usable with a better range to the Gain control, it still gets really dirty when it's cranked but the gain control is far more progressive and usable.

 

there is a great thread by @Happy Jackall about this which is where I got all my info about what spec valves to try.  HERE

EDIT- just remembered that i also swapped out the screws that hold the top "cage" onto the amp, the original ones are pretty soft and easily damaged, i swapped them for some decent socket head (allen) screws, they're M3 thread, and i think 8mm long (I'm lucky that i work for an engineering company so things like this are easy to get, i think i scrounged these screws from the scrap metal bin after the last workshop clearout)
