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.

Subject line gentlemen.
I am sorry, I was sorely tempted by 7N7's post: a pet subject. :D 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!

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

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.

As a near old timer, (grammatically incorrect) I would have thought a little diversification from any boring topic is a good thing and fruitful for horizontal thinking....The best (electronic) decisions on any project are often made by brainstorming ideas in unusual places . The sauna.

I bought a transistor amplifier today...

I'm delighted to learn that others approve of this thread's meanderings.

I bought a Rotel RA931 transistor amplifier today from a charity shop for £45. It's intended to be used with the television to drive some Mission bookshelf loudspeakers that are designed to be driven by a transistor amplifier (4 Ohm bass driver, 8 Ohm tweeter). I tried it out driven by a Marantz CD63mkII. It sounded fairly awful to begin with, but I left it switched on for a few hours to give the electrolytics a chance to re-form (or possibly even reform). I've just played it and it sounded much better. Anyway, to get to the heart of the matter, I decided that a motoring simile was appropriate. It's a bit like a white Ford Escort XR3i; quite exciting, but plenty of errors and no subtlety. Conversely, my LS3/5a driven by a large valve amplifier are Inspector Morse's red Jaguar; refined and subtle, but lacking in a few important areas. I expect that my proposed new open baffle loudspeakers (18" bass, JX92S mid, ESg1 ribbon) will be Rolls Royces; smooth, and deceptively powerful.

Now which loudspeakers would be equivalent to a Lancia Fulvia?

Edit: And I liked the cat site.

Darn it, TerryO, just when I was squaring up for a good flame war! :D

Back on topic: One thing I dislike is the way the language is being twisted for no reason other than to be trendy. For instance, I hate hearing a noun being as a verb, a prime example being 'parenting', as if there were a verb 'to parent'. :rolleyes:

This is legitimate, but how else can we "grow" the language? As we "reinvent" ourselves and our vocabulary, we need to seek the "Windows of Opportunity" that become available. Trendy? I think not, it's more an expression of our "Inner Coolness."
Can't we just agree that it's all good?

Dude! I'm lookin' at ya! :whazzat:

But one of the strengths of the language is its ability to "verb" nouns - ask Wm. Shakspear. Yes, I grant that this particular usage ("verb" qua verb) jars, so it's better if done by those who are sensitive to nuances, but - as was pointed out earlier in the thread - we have no equivalent of the Academie; not that they actually manage to control much (viz "le weekend" and other common French terms). Creating verbs from nouns becomes a concern for me only when the noun is verbed, and then a new, redundant noun is created by back-formation from the new verb.

Onwards! I'm curious about which battles you-all think are won, lost, or teetering in the balance. Here's the sort of thing I'm thinking of:

fewer/less - almost lost, just conceivably redeemable

discrete/discreet - probably winnable, we just have to be prepared to kill those who consistently misuse them; same with complimentary/complementary, I hope.

begs the question (when used to mean "calls for the question") let's hope that this is just a vogue-phrase and vogue-speakers will move on from it soon

Can't decide about its/it's - surely, I say to myself, the usefulness of the distinction means we'll keep it; but then I look at all the text in which apostrophes are scattered at random, and despair.

fulsome used in a complimentary sense (!) - surely only an idiot, or a CEO, would do this? If we can't win this one, then prescriptivists are the Canutes of our time.

I could go on - some of you may think I already have - but I'd like to hear what others think.

Regards.

P.S. Quad ESLs, which I lived with for years, are obviously analogous to the 1974 Guzzi V7 Sport - which I also lived with for years. That I have neither now is a tribute (no doubt) to the women in my life :angel:

Aengus,
You're desperately needed over on:

http://www.diyaudio.com/forums/showthread.php?threadid=102635

There seems to be a small boat outbreak and your expertise is needed!

BTW: I like the P.S. on your post :D

Thanks,
