    Toufeeq and others,
    For all those who really want to get the best from their D/V 336 go to the Rock Grotto forum -look for the h/amp forum, in search, put in Dark Voice 336 and you will find a 3 page thread that covers all you need to know about the D/V, on Pinterest you will see the Fitz and Pink Floyd mods.

    Pink Floyd Mod ...that's new... thanks, ill take a peek. (and three pages of info...thats insane) Joking...hey ther'e more than 3 pages here boss, take a read guys, lots of interesting stuff here..did I get the right link GLLIC dWEller? ----> http://rockgrotto.proboards.com/board/8/headphone-amplifier-forum?q=Darkvoice+336 And the user PinkFloyd Mod, that's very interesting, almost looks like the Fitz mod, but I don't really know, seems like replcaing said caps lowers the frequency range for 32ohm headphones down below 20hrtz...now thats proper... as it is now the stock caps were set for 300ohm headphones, which solidifies my original thought that the Darkvoice excels with high impedance headphones. very interesting. ( I can see now how users revel in said mods if they don't own high impedance headphones) Having said that the only low impedance headphone that plays well for me with the Darkone is my Fedelio X2, would a PinkFloyd mod enhance this experience? Maybe, as it is now, highly enjoyable. :)

    So I’ve been on an adapter craze lately, and had been testing some 6f8g tubes with pretty good results.

    Most recently I’ve tried the 6C8G Tung sol round plate. I’ve had very good results. Very good. :). Now the scuttlebutt is that this tube is sonically similar or even potentially identical to its 6sn7 brother, but I don’t have a comparison tube. Has anyone done a comparison? I found the tube from an eBay seller that was selling different 6C8G tubes, for a whopping cost of $25. There are others available for higher cost, but well well under the 6sn7 rate.

    If we can confirm the Sonics this may be a real bargain out there, only needing the 6f8g adapter.

    quick edit: it did take a full two days of burn in, started with a huge left channel hum.

    Yes these came out before the 6SN7 tubes and do sound spectacular, I just have the Sylvania version and would love to have the Tung Sol version of that tube only they go for roughly $120+ whenever I'm in the hunt, if you got that tube for $25 that's a huge score there buddy, Kudos!

    The seller still has three other types up for $25. I think with patience they’re out there for a deal; or at least a lot less than ts 6sn7 round plates, those are astronomical right now!

    6C8G has a gain of 36, almost twice the gain of 6SN7 or 6F8G, so it is closer 6SL7.

    So I doubt it will sound similar to 6SN7 or 6F8G. If you like the sound of 6C8G, you can possibly also try 6SL7 (assuming your amp can take 6C8G or 6SL7). :)

    Do you have a Tung Sol 6F8G round plate? I've to date never seen them, only ladder plates which I have, but sonically, they do sound very similar to the Tung Sol Mouse ears 6SN7. Lol. the 6C8Gs you can still get for a bargain, but the 6F8Gs/VT-99 have caught up in pricing, they can also reach high up there in the stratosphere for sure as well depending on the ones worth geting.

    Just the round plate 6c8g. I wish I had a 6sn7 to compare it to. Sounds excellent.

    That's what I meant, the CF8G Tung Sols... Keep forgetting there's 6C8Gs out there. Would love to have the round plate Tung Sol CF8G, that would be the cats meow. :)

    Well if anyone can find them, its you JKDJedi a.k.a. The Tube Hunter. I'm still impressed at the speed you found a genuine Lansdale. That was really really impressive. :grin:
