Tube replacement for my Eden WT800

[bigevilman]

Hey guys

Last couple of gigs I've had excess crackles and noise from my amp, so its time for a replacement pre-amp tube me thinks.

As I've never replaced a tube, or have any idea of the sound differences, have you guys got any recommendations?
The manual says to use either a 7025 or a 12ax7, but again, whats the differences?

Cheers

Joe

They are the same valve.

I have a matched pair for sale .... [url="http://basschat.co.uk/index.php?showtopic=83755&st=0#entry800063"]http://basschat.co.uk/index.php?showtopic=...t=0#entry800063[/url]

Check out watford valves

They have a nice selection, anywhere from £8 each T.A.D. to NOS American philips or GE.

There is also a 12AX7 test report download, which is quite an interesting read, if you are into that sort of thing.

AFAIK it wont make any difference to the sound.

I went through this when I needed to replace the valve on my wt 400 and I cant remember the technical resons why but apparently the pre amp valve doesnt colour the sound.

Ask the question on the eden forum
