Hi guys I emailed Nik about it and am awaiting reply however I thought I would put the question forth here.

I received my amp completed by Ceriatone. a few days ago it sounds great.  I got the tubes with amp. JJs

One of the 6L6s is running hot as blue blazes.  (I trade sockets and the same tube hotter n hell.)

The plate inside glows bright orange almost red.  The Red JJ logo on outside is no longer red but a brownish red due to heat.

No issues with other tube in either socket normal glow inside. Just the one. To reiterate the hot tube is hot in either socket.

Never saw this with any of my tube amps over the years.

Anyone have any ideas. I am assuming it is not the bias as I figure they adjust that before shipped for tubes shipped. 

Using Klein with Rocktron Intellifex.

I am afraid to run it as I don't want to damage the amp.

Thanks for any help in the matter.  I am sure Nik will take care of this as I have only heard good things about him.  The amp does sound nice I must say very pleased just that dern tube.

The tube is off spec - and therefore useless.

The tube is 'running hot'. This means that the bias is set much too high for this particular tube. If you turn down the bias pot the tube would probably run cooler, but the other output tubes would the run too cold.

Just get anoter tube.

Thanks fenderman I thought it must be the tube itself.  I don't know if Nick will replace it but would be nice.  Smiley

I told him I would send him an image of it if he likes to show how the plate itself is glowing to confirm my issue.

Anyway we will see what he says.  I appreciate it.
