Raytheon 5751 Versions

Try the G.E. black plate triple mica square getter 5751's from the 1950's. A better sounding tube all around than the Raytheons 

I have the Ge Black Plates, the Raytheons are a bit brighter in my system which I need. I use Joes Tube Lore for guidance since he uses the same exact speakers as I do, so everything is pretty close.

Thanks for reply!

I used to have the 5751 windmill getter with my tube headphone amp about 15 years ago. Sounded amazing with great detail and delicacy. Lush and warm without being mushy. Raytheon 5751 windmill is king of 12ax7 just like Raytheon 5814 2 mica black plate is the king of 12au7 (I had a 12au7 tube hp amp too).
