I only saw it once on one of my tubes but I can't even remember which one.

This is fine it is just electrons that are missing the plate and hitting the glass

IF the amp is cranked up it will dance with the music sort of neat enjoy it.

 

The bad stuff is a pinkish blue that is inside the plate and sometimes the whole inside

of the tube will glow like this. Usually the tube draws lots of current when this happens.

The tube I said was bad most of the inside lit up and the cathode current meter pinned.

Glenn, is there any 3DG4 replacement tubes? I'm leaning to you older chassis now, not patience to wait. Is the old chassis like WA6 and new chassis like WA22 in size?

No but I will send two with the amp and they are cheep or you can put in a 5 volt rectifier.

 

Yes the Old chassis is like the WA6 and the new is about the same size as a WA22

5AU4 is a good alternative.

I do like the WA6 form factor. I will let you know if I want to get the old chassis and save than $100.

Yes it has a smaller footprint and takes up less room.

I'm going to the doctor tomorrow.

They are removing my head.

So I have to fast for 24 hours.

No food.

No wine.

No apple pie.

 

But lots of music until then.

 

I made this last night.

Steamed halibut over stir-fried vegetables.

 

Now I'm really torturing myself.

A NOS 5AU4 here costs $27. :(

It can take GZ37 but not GZ34? Good and bad news, good news it is cheaper and bad news is I like the metal base GZ34.
