A simple question for now: what do you think of driving a power tube (not extreme ones) in a PP with a cathode follower, dc coupled? Are there really advantages in DC coupling (assuming that I don't need necessary A2 drive)?

Hi Giaime...from this post I understand that you don't own Morgan Jones 3rd edition of valve amplifiers!? The crystal palace driver stage does exactly what you want (would also make a good driver for a PP EL36).

You're right Erik, I don't have the book. Thank you very much

Yes! I second that.

I feel the book has to be read more than once to get the most value. Not everything, but there is a lot in there.

No, it isn't RDH4, but it is the most practical book in my collection. Anyone who has soldered a tube socket should own one. My humble opinion, that is. Maybe someone could organize a group buy for those without a copy.

------> Giaime: I saw a copy @ RS ... I can't remember the price but I guess it should be as expensive as a quartet of EL36 can be (LOL)

Ciao

Yeah, considered that I almost had a fight with the shop guy... maybe I told this story to you?

Does anybody know if a 4th Edition is looming on the horizon?

If you look at it, Morgan's quite consistent on his release gaps- 1995, 1999, 2003.

Based on this, a new one *might* arrive in 2007.

How about The Tube Amp Book (Spiral-bound)
by Aspen Pittman? Is this on the same caliber as Morgan's?

OK, he owes me a beer.

From what I understand, the 4th is in the works, but won't be appearing anytime soon. Honestly, I don't think there's any other contemporary book to compare, and I came to the book with a deep sense of skepticism. "Valve Amplifiers" is not as broad and deep as RDH4, but it's got a lot of new stuff RDH4 didn't have AND it's written in a very accessible style. Jones has a real talent for teaching.
