Thanks Glenn. I told you I was dumb. Lucky I have you to build my amp.

After consulting with Stavros, I have decided to call my amp "Φως Αποκάλυψις", which I believe means "Light of Revelation". I think in classical Greek it is pronounced something like "Fose Apocaloopsis".

Bought NOS Lorenz C3G tubes yesterday for about $40 for the pair. Seemed reasonable to me. Looking forward to trying them out. Is it difficult to remove the shield?

Glenn - My amp won't have any rectifier tubes, will it (as I am getting Lundahl transformer)? I don't mind either way as you know what is best/possible. Just want to keep my eyes peeled for decent prices on the required tubes.

Warm regards

Nathan

   If you must remove the shield just use a file along the edge of the tube  its alluminum so very soft metal   but base will come off  make shure to place a mark, to position centering guide pin in same place it was before

Any advantage to take the C3g metal cap off or leave it on??

Personally I would leave it on. It was designed with the metal shield for a reason.
Taking it off only makes it look cool and serves no purpose.

And I would add, it doesn't even put on much of a light show with the cans removed. Not worth the trouble in my opinion. And like Glenn says, it was designed to provide 10,000 hours of service inside those little metal cans, so my thinking is it is best to leave well enough alone.

Wow.... 10,000 hours, that is fantastic!
 
Yeah, why take them off.

Nathan you will still have tube rectifiers unless you wanted your amp designed to use SS diodes to perform this job.  Rectifiers convert AC to DC, this function is independent of the transformer providing the incoming current.
 
I took the shields off my C3g purely because I think they look ugly with them on.  If I ever have a need to switch to my backup pair I'll take the shields off those too before using them.  It's a hobby and its supposed to be fun, I say do whatever you want and enjoy.

Sorry. Stupid Nathan strikes again.

Goodbye.

I learn new things about audio everyday Nathan.
There's nothing wrong asking a question.
 
I like the name you've chosen.
 
The last amp Glenn gave me is named GRETA Glenn-R-Experimental-Tube-Amp.
I need to se it up soon.
Steven I know I am very very bad for not doing it sooner.............sorry

I have yet to name my amp. Sometimes, I think I should call it "気高い" (Kedakai) which is Japanese for "Sublime". And other times, "力" (Chikara) for "Power". But for the time being, "The Glenn" seems to fit.

That's ok Stavros...I hope you've recovered from your weekend feasting!
 
I have been acquiring a heavy position in GRETA's "secret" output tubes.
 
If these tubes become the Next Big Thing, we could make enough money to buy a new DJ rig for the Beach Bar!

 

[rosgr63]

You are so right Steven, you never know!!!!!!

Glenn,
 
I am quite sure this is something I don't have to worry about, but thought I should double check to be sure....
 
If I remove a 12SN7 and insert C3gs, do I have to change the 6/12.25 switch back to 6 volts?
