Tube noob inquiry- EF806 - 12AX7

[xXDaveyJonesXx]

Ended up with a variety of tubes for various projects and I'm curious, is the EF806 a viable drop in replacement option for the 12AX7/ECC83 or would I be somehow asking for trouble? Is there a major difference in design between these types?

The amplifier in question is a 100W Framus Cobra, if that helps any.

Thanks

I have never heard of it, but google results seem to say it is not.

Definitely not compatible with 12ax7 ! Its a mini pentode, not a twin triode.

You sure it's not an EF86 - https://www.thegearpage.net/board/archiv ... 44179.html

My Fargen Bastage has one and what a killer little amp. Check it out. http://www.ultimate-guitar.com/reviews/ ... index.html

Oh yeah and either way 806/86 not compatible in a 12ax7 replacement capacity IMHO.
