I've been enjoying anew listening to my favorite music now that I've gotten a lightly used pair of Sennheiser HD 600's hooked up to a Little Dot MKIII. I recently took the dive into tube rolling and purchased a pair of Voshkod 6ZH1P-EV as they came highly recommended in Dept_of_Alchemy's post on tube rolling for the MKIII. I really like the results. Penchum's review of the MKIII mentions the Voshkods and then goes on to say the GB-5654 Sylvania Gold Brands are the best EF95's he's used. I realize there's a law of diminishing returns going on here and that because I paid 'x' amount for my Voshkods doesn't mean paying '3x' for the GB-5654's will give me sound that's three times better. Clearly that's not even really possible. I have realized however I really lack some basic understanding concerning the equipment and I really should educate myself so as not to be the blundering idiot who pays a substantial amount for something just because it's being offered for a substantial amount - I may well end up disappointed. With that in mind, some questions (some rather stupid):
- What is the best layman's description for the how and why of the circuitry of tube amps? No need to get too detailed, just start with the input signal and proceed with each major component. Again, layman's.
- What are all the contacts (metal legs sticking out the bottom) for? Does each translate into a section of the sound spectrum? Obviously we're dealing with current here but I'm wondering how it all works.
- Are the power tubes that important? Or I guess a better question is do they have that big an influence other than gain and they'll mess everything up if not well matched?
- Why does each model of tubes seem to have three different model numbers to it?
- How long does a set of driver (signal) tubes last when taken care of?
- I've got a Little Dot MKIII situated in a bit of “cubby” shelving which is against a wall. Basically there's not a whole lot of air flow around the amp when it's turned on. Will this affect the sound and/or longevity of the equipment (should I have it more out in the open)?
My musical tastes are all over the map: classical, metal, techno, rock, some jazz, even books on CD. I do appreciate Head-Fi and the candid community here; even if I rarely post. There's always good advice and as I said, I'm really enjoying the results of my purchases.
