Whoops, I had glanced at this and thought for a moment that it only had 4 tubes:

SeeHer - did you say that you got some kind of balanced output installed on there?  If so can we get a close up photo?

 
No, I don't have a balanced output.  I had asked for various combos of in and outputs on a WA6 until Jack finally said "Enough! Get a WA2!"
I should have asked for a switch for the pre-out as it makes all sorts of nasty noises as the tubes heat up.  Is that normal?

1 quick question for using the 6GL7 Tubes in the WA6SE i need a 8pin to 9pin adapter am i right?. is the adapter the ordinary 8pin to 9pin adapters or it needs a special resistor inside it?.
 
ThX

Yes, you need an adapter. I'm not sure if there is a resistor in mine, as they are Jack's adapters, and are guaranteed to work regardless.
 
However, I would contact Jack. This is especially true for 6SN7s: These adapters have the same pinout as a 6SN7. If you decide to give 6SN7s a shot, BEWARE. It appears that 6SN7s in a WA6-SE REQUIRE an internal resistor.

I think it depends on the tube.

It is usually a good idea to let tubes pre-amps warm up first before engaging or turn on the power to the upstream device that is connected to the tube pre-amp outputs.My Melos pre-amp does have a delay relay for the outputs. Some of my tubes will ping a little while warming up.

You mean the tubes make noise, audibly coming from the tubes, without headphones on? Yes, it's  normal for a lot of tubes as the meshes/plates/elements heat up or cool down. It's the metal expanding and contracting.

A bit OT: What power cables do you use?

 
I use Nordost power cables and Isotek mains conditioning. Have used Shiva in the past for DIY and mod projects as it works well in DC applications as well as AC. Maybe some placebo effect going on there though!
 
The Valhalla I hooked up to my mains conditioner brought in substantial benefits to all the downstream components, rest of my kit is wired up with Vishnu after the conditioner.
