12 months now no problem
Bought 2 pair but still on the first set


And these are definitely better than any of the 12AU7 tubes? Are you using the 6350 Black plates?

Those are the taller tubes requiring adapter?  Mine at work have totally f'd up the sound and I am back to the mullards luckily it didn't seem to cause damage.


Right, thanks for that. Safer to stay with the 12AU7s then.

The NOS Mullard CV4003 are very good. We have a few tested and matched pair available. 
 
 
yes... agree it should be a proper switch or better yet just turn on when the WA7 volume knob is turned above 0.

 
It's complicated... We rather have a smooth, solid feeling and channel accurate volume control than one that does everything. Jack of all trades, master of none would apply here if we tried to do all-in-one knob/button.

I think he's referring to the knob on the tube supply. Also, how much are the mullards going for? As for the connection on the umbilical chord, is it possible to get one made or is it some proprietary technology?

it's certainly possible to design it to where it doesn't compromise anything.  perhaps even using an optical relay that signals the power supply to turn on so as not to interfere with the electrical signals of the pot. a creative solution would not only cost less to manufacture without the machining of the p.s. knob or mechanics but look and feel a lot more impressive. provide a magical 'it just works' sorta experience.

Upgraded the tube supply from stock to Tung Sols and wow, what an upgrade for AUD$40!

Is it normal to have some disturbance in the right channel on start up for a few seconds, didn't have this on the stock tubes.
