Re: 6H13C

Long story made short. The 6AS7 and the 6H13C can be interchanged in the Atma-Sphere. I think ALL Sovtek and Svetlana's are 6H13C's. They do not make a 6AS7. They only add that stencil to the tube for our benefit. When getting 6H13C's, try to get them with 'OTK ##' on the side. These are military tested. The higher the number the better.

There was a similar question some time ago.
I know because I asked it.
