EC900 for Headphone amplifiers
Hi to all :D

I would like to build an amplifier with small tubes as EC900 or similar
in website I have found this Adam's Amplifiers: Subminiature
very interesting, but I prefer the classic tubes with base. :rolleyes:
Is EC900 a good choice ?

My idea is to supply all with 12V lead battery with a self oscillating stage for H.T.
Because I do not trust myself of mains supply especially with in-ear headphone :hphones:

I have found in my old-stuff these tubes : EC900 ,6AF4A,
Can I use them ? or is better a classic ECC82/3/8 ? :dead:
