    For sure @connieflyer ...anything Chip Davis does is fine by me - a true master of the 'New Age' genre. And the 'Mannheim Steamroller' series is certainly one to cherish lol :smile_phones::smile_phones:...CJ
    ps. And the quality of recording is second to none...:ksc75smile:

    Let's hope so bt...but with all our tubes being brand new, all readings are likely to be quite high lol (so a mixed blessing, it looks like :smile_phones::triportsad:). Fingers crossed nonetheless :fingers_crossed::fingers_crossed:.

    Hi S. Interesting that in your 300 ohm Atticus the hum is louder than the 600 ohm Beyers...which would indicate impedance differences are not such an obvious factor after all lol, given my experience with pre amp out duties and my 32 ohm Meze Empyreans...the former totally silent, with infinitesimal hum in the Empys.

    Ah well, perhaps the moral of the tale is...go for the Empyreans lol!! :wink:...they sure do love Euforia with the KT combo especially...:beyersmile:.

    Yes I thought that too, re the Empyreans I'd love to go for a pair, problem is my wallet wouldn't!, maybe when I win the lottery! :ksc75smile:.

    Quick question: I was rolling my 7581A's back into Elise and when i was placing them into adapters for 6AS7G socket, the plastic guide pin center portion of one of the 7581A broke of in the adapter. I was able to remove it and have placed the tube into the adapter with correct orientation, seems to be working normally but curious if this could pose harm to the tube or amp in the longer term. :triportsad: Hopefully not!

    Hi S. All I can say (seriously!) is get saving lol...they're worth every penny, despite my initial hesitance in spending that kind of money on headphones...CHEERS!...CJ

    I'd better get saving then, or I could just try and sell the missus!.

    Actually I've done the same thing with one those too, also have a couple others with broken guide pins and they work fine, and as far as I know there should Not be any long term concerns either.

    Hi LW...no problem at all. And well done on getting the correct orientation lol! Sometimes you can see where the locating protrusion was, otherwise it's not so easy - but a cheap multi-volt DC charger/adapter (1000mA) set at 6/7V will soon trace the heater pins.

    I keep threatening to put mine (the missus, not the Empys!!) on ebay...but can't think what reserve to put lol!!...(daren't let her know it's too low :astonished::wink:)...CJ

    I did exactly the same when fitting KT66. Makes no difference just take care when aligning tube.

    These things happen. For me the easiest way is to stick on a little piece of red tape indicating the location of the ridge on the guide pin. As mentioned, if you look carefully at the base, you can almost always see a little notch where that ridge was located.
    If you really are worried about the right orientation, you can buy octal rings with a guide pin and attach to the tube.

    Thanks for all the help on the broken guide pin. I do have the adapters fit correctly and plan to leave them securedto eliminate futre mishaps. If I do remove them, the tips above will be front of mind! Thanks again.

    Lol yes, think mine would be more insulted by a low reserve than the thought of selling her!.

    Ah yes, mon ami...discretion certainly is the better part of valour lol! :wink:...(and safer!! :L3000:).

    Anyway folks, back to more serious (?!!) matters, I'm happy to report that the slight hum from my setup with the KT66/88 combo - as some of you also seem to have - is gradually diminishing from my more-prone HD650s, and not noticeable with my Empyreans now. Hopefully y'all will experience the same with a good bit more burn in. And gain comfort also from the fact that my mesh plate Valvo EL11s had the exact same very slight hum, and 2 years' constant use caused no harm to the amp whatsoever...:smile_phones:.

    And I found some interesting info that might just give a clue as to the esteemed ancestry of our reissue Gold Lion KT88s (supposedly made to the same spec), along with a current asking price for an original...:astonished:!!!...

    No doubt the level of quality control can't quite match the original, but reports that the new production tubes aren't too far off the NOS would certainly explain the superlative results I'm now getting from my own 88s...especially when driven by the 66s. And their price is much more to my liking lol! :ksc75smile:...CHEERS!...CJ
