I have a CD-3 myself, so I am really interested to hear how that turns out. Why are we looking to reduce a subjective experience to objective criteria anyway? Voltage drop across each power supply resistor was ~33V. I started taking the innards of the Darkvoice apart tonight. Regardless, here's some picture of the insides. Honestly these babies sound awesome after those mods! > Ducky Shine 7 (MX Black) - Zowie FK1+ White w/Artisan Hien HI-SF-JB-L - Sennheiser HD 600 w/AMP DarkVoice 336SE (Tubes: RCA Jan 6AS7G + Ken Rad 6SN7GT VT231) Reações: duarte.jean , J@ckB@uer , brenopapito e 9 outras The DarkVoice 336SE for around $200 sounds like an affordable, favorably reviewed tube amp. After reading many threads including suggestions for Mod I had hard time to believe Darkvoice would design and manufacture any amp that would not work well with driver tube (6SN7). I previously owned a similar OTL Darkvoice 336SE amplifier which uses 6080 and 6SN7 tubes, so I have many of these types of tubes on hand. I would have loved it if it had been attached by four hex key screws, just like the back plate. Ian and Rachel ensure not only that the product does what is advertised and that the circuit is accurate, but also that it is not dangerous or troublesome. If that was the measured voltage than I wouldn't be to worried about it. I’m glad I found this post! The new Tung-Sol more so. I'd also like to extend this thread to mods on a Darkvoice 336SE to avoid making two separate threads. For reference, here (link) are the insides of that. We’ve selected snippets of the most pertinent parts of each … Or am I doing math wrong here? Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. Pretty cool update: I stripped everything out of the inside except for the tube sockets, headphone jack, potentiometer, LED PCB, and electrolytics. I'm trying to push them from the other side while unscrewing, but it's a bit difficult. Nice mods going on there mate. I was wondering if anyone could recommend a capacitor to try that would actually fit in the limited space. Ah, the old buzzing 6SN7 tube. Audiophile • DarkVoice 336SE OTL Headphone Amp Hahaha.

Quand je dis parfait pour les squares, je veux dire qu'elles seront d'un niveau bien supérieur à ce que donne le meilleur des casque.. donc non limitatives, c'est une question d'échelle. I hate to be a bit of a bummer, but the Sonicaps are rated at 200V, and the board states those caps should be at least 275V. Bummer on the effective lack of progress, but keep on working on it! Clarity Caps are hard to beat, and with those values, they should fit in the stock location fine. I didn't feel like modifying the amp even it's simple to do. Check resistors. Veech Space In Sounds Thread Starter. I decided to take a break from the Darkvoice for a bit, thinking that focusing on the Yaqin CD3 might give me something to do for a few days.

Location: Los Angeles, CA. Blows away my DarkVoice 336 and my Woo Wa3. Discussion in 'Modifications and Tweaks' started by rtaylor76, Jan 4 ... For those of you with experience with both the Crack and 336se ... which of the two runs WARMER? Obviously overshooting on the component voltage rating will never hurt, but as long as you are exceeding the voltage of the circuit, no problems! The Darkvoice is notorious for NOS and new 6SN7 tubes buzzing. I was just thinking, obviously there is something wrong with there being a measured resistance between the two channels. The subtleties of music and audio reproduction are for those who appreciate it. It looks like you're new here. I tested the old potentiometer, and no such continuity existed between the signal inputs even though they shared a common ground. I’ll try the burn in method but I’m enjoying it too much at the moment even with the stock tubes (they’re not bad, IMO). This is one reason I prefer to buy Chinese equipment with the Grant Fidelity name on it, even used like this buffer. If you want to get involved, click one of these buttons! What's required for modifying a Darkvoice 336SE (OTL) for low impedance headphones For the original Fitz mod (to reduce or eliminate tube hum), two 220uF capacitors rated 16v+ are required. That would have been beautiful. Re: Mesures des casques sédentaires, mods et EQ | alphatak par cleriensis » 25 Avr 2019 10:02 bonjour à tous, test en cours de l'UtraCurve de Behringer.. pour ceux qui veulent rester en pur hardware, sans passer par le PC. Why they would design the amp like that instead of opting for 250V caps, I have no idea.

Attachment is the closest thing I have to a representative schematic of the signal path based on Google and visual inspection of pictures. What's more worrisome there is that the main supply filter caps are 820uF/200V, meaning that one is constantly running essentially right at its operating point. Every audiophile knows the importance of a powerful amplifier, and the DarkVoice 336SE definitely falls into that category. There are a few ways to overcome this issue: 1) Burn-in of the 6SN7 tube. Is there a difference of voltage at different operating points and loads? You'll need the appropriate sized tip hex (allen) key to remove all 8 hex screws on the faceplate. Super excited cant wait to hear it. Power up, measures just fine (again, a bit high on the voltage. The through-holes where the old resistors were were a little small, so I had to get somewhat creative with how to pack them in. What did the power company say about your higher voltage service?

Darkvoice and Crack Mods. :eek: Watch out as that could cook any of the electronics at your house. The dilemma now seems to be that all of the voltages in the amp are markedly raised (240VDC at first filter, 98VDC at coupling cap, 8.4VAC on heaters).
