Equaliser Posted August 19, 2015 Posted August 19, 2015 You mean filter cap for the 6SN7. It was originally posted on headfi years ago and anything between 100uf - 330uf and at least 10-25v will do. Any standard electrolytic is fine, you can use axial, normal stand off type or bipolars.

Thanks For the back power tube you can use the 6AS7G, 6080, 5998 variants. The front driver tube use 6SN7 or you can use 7N7 with adapters. I'm currently using these:- RCA JAN 6AS7G power tube Sylvania 6SN7GTB NOS Chrome top driver tube Sounds really good and doesn't cost an arm and a leg. 1

Thanks I really liked the RCA Jan 6AS7G - its warm and spacious, and a joy to listen to. A real bargain - you can stock up on these tubes and have a lifetime supply. As above theTS 5998 is definately more detailed, but I found it less enjoyable to listen to with my cans. I love the GE 5998A which is expensive but less costly than the 5998A/ WE421 or GEC tubes...indeed I am listening to the GE 5998A now in my integrated amp in my regular system. Love that tube!

Equaliser Posted August 20, 2015 Posted August 20, 2015 (edited) For front input stage tube you can roll a ton of equivalents with the appropriate adaptor: 6F8G, 6DJ8, 12A/B*7, 7N7, dual 6J5, dual 7193, 6H8C, 6BL7 etc etc. The common drop in equivalents are 5998, 6SN7GTA/B, VT231, WE421 and 6H8C's.

DMax Posted August 20, 2015 Posted August 20, 2015 Awesome...I will try get onto those tubes soon! Thanks It's my first time rolling the tubes for it even though I have owned it close to 2 years LOL
Odyssey Posted August 20, 2015 Author Posted August 20, 2015 Yup DefQon is the expert. Meanwhile picture of my 1st ordered tubes glimming and shining. You can use as a mirror 1
DMax Posted August 22, 2015 Posted August 22, 2015 Just wondering if you guys get hums from a 6sn7gt tube?
Odyssey Posted August 22, 2015 Author Posted August 22, 2015 That's the tube singing Welcome to the world of hums lol. I had no hums from the Darkvoice that I bought with the extra tubes given by the previous owner. My recent addition of the near new pair of Sylvania 6SN7GTB Chrome top hums sometimes. When it doesn't hum it sounds so sweet. Maybe it needs to settle in. Try it with different power tubes. Is this a new tube?
Equaliser Posted August 23, 2015 Posted August 23, 2015 I've had a few 6SN7's hum before the filter cap was installed. After it was installed no hum.

mkaramazov Posted August 26, 2015 Posted August 26, 2015 Hi Dmax I think DefQon has previously given the answer to this (below). Google mods to the Darkvoice and you should find more details That said, you should probably only attempt this if you have some electronics experience (ie can use a soldering iron, understand safety working with valve gear etc).

Thanks, forget it then. I am useless with electronic stuff. I thought it was an adapter that simply goes between the tube and the amp. LOL cheers
Odyssey Posted August 27, 2015 Author Posted August 27, 2015 Not all tubes hum. New ones might need burn in initially. From my purchase recently, only a pair of new Sylvania 6SN7GTB Chrome top hum. I'll save these for a new tube amp that I'm getting. Another Sylvania Gold brand 6SN7WGT used but in good condition is perfect and silent without hum. My old Motorola 6SN7GTB and RCA 6SN7GTB doesn't hum. Non of the power tubes induce hum. Seems like only the driver tubes (some of them) hum. I've been happy so far with my un mod Darkvoice on tube rolling. Very happy indeed.
DMax Posted August 27, 2015 Posted August 27, 2015 Do you find the bass to be lacking on the Darkvoice?
Odyssey Posted August 27, 2015 Author Posted August 27, 2015 Absolutely not. This is just an entry tube amp but I like the warm and lushness. I have no other tube amps for comparison but I have to say I like the bass now with the hd650. Some tubes have good bass and warm. You have to read the 6SN7 reference guide. Try the Ken Rad 6SN7GT Vt231 but it's expensive. I'm getting another tube amp which is supposedly much better. Well when I get it I'll be able to compare
Equaliser Posted August 28, 2015 Posted August 28, 2015 (edited) You need some Crack mate. This is what my DV 336SE looked like 2 years ago without the filter caps installed. Edited August 28, 2015 by DefQon
Odyssey Posted August 28, 2015 Author Posted August 28, 2015 (edited) Probably LOL I did think about it but I don't think I can solder and I don't like the look. Was thinking about La Figaro 339 but decided to take my chance with new comer Elise from Feliks Audio. Edited August 28, 2015 by Odyssey
DMax Posted September 13, 2015 Posted September 13, 2015 (edited) Any of you want to sell any tubes you're not using? Thanks Edited September 13, 2015 by DMax
Odyssey Posted September 13, 2015 Author Posted September 13, 2015 (edited) PM you. Ok you're not PM'able What tubes are you looking for? Power or driver tubes? Or what tubes do you currently have? I just bought a pair of Mullard CV2984 / 6080 and I'm still smiling like a buffoon. Edited September 13, 2015 by Odyssey
