Need help drawing 12ax7 in Eagle

emogstad · 26th August 2011, 11:16 AM

Hey guys!

I've just built a simple proto preamp for a guitar practice amp that I want to build. It works well and all, but...

I want to order some proper PCB's for the project, with PCB mount tubes. I use the "tubes"-library from cadsoftusa.com. How do I get the heater in with the two triodes in the schematic?

I've tried to add a separate heater, but it won't add to the excisting tube. This is a bit frustrating :P

Thanks for any help!

Here you have all the libraries that I have. Here you can find a folder called "tubes", this is what you need to add on this case but all's are usefull.
