Ah, a man of taste! My own favourite, right now, is a 6SL7 LTP splitter with pentode CCS in the tail, followed by 6SN7 diff driver, and trioded EL34s in the output. NFB is cross-coupled from OP tube plates to 6SL7 plates. No hum or noise whatsoever! I think that configuration may possibly not have enough gain for pentode mode, though, because of the heavier NFB required, but I'd like to try it.

It is always a pleasure to find that someone agrres with one!

I like the idea of the pentode CCS (more glass). I have written about these elsewhere in this forum - in fact my 813 amplifier in its final version, had a pentode sink (an EL822) sitting under the 6BX7 driver stage.

For a high gain input stage, I tried many types, although never 6SL7. Amongst my choices were EC8010, triode strapped E280F, triode strapped D3A (really good this one - mu 80 and piles of gm) 6AN4 and finally in an idea for a riaa stage that was only half-built, WE416D

I also like very much the pentode cathode follower. Here is somewhere where a pentode (run as a pentode) can also do some serious good.

I am sorry, I was sorely tempted by 7N7's post: a pet subject. That is no excuse, of course, and I realise I should not have hijacked this edifying thread in so cavlier and self-indulgent a fashion. In truth, since just about everything I can think of on the proper topic has already been said, I suppose I'll just have to stop posting to this thread. (No promises, mind you.)

I agree completely, it's time to exercise some self-discipline and return to the main topic which is "Spelling, capitalization, and grammar."

I must ask that there be no more diviations from the subject.

Remember Gentlemen, this *IS* the tube forum!


Best Regards,

Yes quite so - and mea culpa again from me...

Although in Blighty, we'd call it the "valve" forum.

I recently suffered this "word";

"Optioneering"

(Offered at a pensions presentation, and no, I haven't any idea what it was supposed to mean, either.)

Ah, the culprit! You started this thread, now lots of us are sinking in it - it's like quicksand!

We pensioners sometimes have trouble hearing clearly. Maybe what you heard could have been: "Auctioneering"?

Sadly, the "word" was typed in a Powerpoint slide, what I heard was total bollox.

Edit (re. quicksand): Guilty as charged.

I thought that perhaps I should point out that in my last post, where I admonished the participants of this thread to return to the "main" thread of Spelling, Capitalization and grammar was made entirely in jest.

I have to say that this thread has gone all over the place, many times quite wide of the mark and, for me at least, has been both enjoyable and very educational. I have never thought about, nor known the first thing about what problems might exist with the power grid of other places or countries of the World. The opinions about amps has been very informative and has caused me to realize why some of the choices that are made can reflect very real and practical solutions to realities that I was only dimly aware of.

If anyone thought that I was "uptight" about the meanderings of this thread, I apologize as that is quite far from the truth. This actually reminds me of a conversation one would have among friends in the local tavern or pub. Quite refreshing actually, compared to many threads that I have read on this and other forums over the years.


Best Regards,
TerryO
