| Preamp Deal of the Century The anode of the first 6SN7 triode stage is connected to the grid of the second stage in the Chenin. The output wires in the stock version are connected to anode II and cathode II.I did not change any operating voltages in my Chenin. The only thin... | |
| Transistor Preamp that sounds like a Tube Preamp? And to add to Gregm's post, with a tube preamp you can tailor the sound considerably by swapping tubes, so if you change speakers, amps, cables, etc. you can often adjust the tone back to where you like it by throwing in a different tube.I know my... | |
| Preamp Deal of the Century I just finished an extended listening session, and a few things stood out with the NU 7193s.The highs are extraordinarily detailed and sparklingly clear. They might be fatiguing if it wasn't for the total lack of glare - these tubes are clean, cle... | |
| Supratek Owners - Simple Mod to Run 7193 Tubes Just to clarify, no holes need to be drilled in the preamp! I was asked this question in an off-line email, so I thought I should post a clarification. I specifically designed this mod to make the fewest possible changes to my precious Chenin (the... | |

| Preamp Deal of the Century I understand, Kg. Even though I thoroughly studied the circuit and went over the mod dozens of times in my head before I did it, I still had quite a bit of anxiety when I pushed in the power button. Happily, there was no factory smoke released. | |
| Supratek Owners - Simple Mod to Run 7193 Tubes I copied this into the "Deal of the Century" thread, Slowhand. I don't know too much about the Cortese, but if the 6SN7s are wired the same way in that preamp I don't see why it wouldn't work.The whole idea is predicated on the fact that the 7193 ... | |
| Preamp Deal of the Century I originally posted this as a separate thread but am re-posting it here at Slowhand's request.I have been intrigued by the 2C22/7193 tubes since reading about them in the "Supratek Tube Swappin'" thread, especially the comments from Audiogon membe... | |
| Supratek Owners - Simple Mod to Run 7193 Tubes I thought I would add the part #s and prices for the adapter materials:From The Tube Center:Tube Base: 8-pin Octal Tube Base ($2.00 each)Socket: #SK-8 Ceramic Tube Socket ($2.00 each)Caps: 6DQ6-type, Small Ceramic Cap ($2.00 each)From Newark Elect... | |
| Removal of Optimus/Lineaum dipole tweeters Press Mortite (rope caulk, available at Home Depot) into all the nooks and crannies of the faceplate to dampen it - works great and doesn't dry out.Glue a piece of felt (cut to size) to the top of the cabinet, under the tweeters. It will help to t... | |
| Input Impedance of Chenin Linestage - Anyone Know? I emailed Mick from Supratek and he kindly responded even though Supratek is no longer. His reply:100K input impedance with the manual volume control50K input impedance with the remote volume controlBoth values are for the Chenin linestage. | |
| Amp Shootout: S-30, Ref 9 V2 SE, Raven, DAD-M100 Follow-up: I have replaced the Russian 6SN7GT tubes in my Supratek preamp with NOS RCA Gray-glass 6SN7GTs and all I can say is WOW. The warmth of the RCAs removes any trace of SS hardness from the system - it now sounds every bit as seductive as i... | |
| 6SN7 Tung Sol Reissue Mullard 12AX7 any comments? I have been using the Tung-Sol re-issue 6SN7s now for several months in my Supratek Chenin preamp. This weekend while listening with my wife I decided to swap the EH tubes back in to see if she and I would notice the difference. It was very appare... | |
| Removal of Optimus/Lineaum dipole tweeters Yup, the whole thing comes off in one piece. | |
| Removal of Optimus/Lineaum dipole tweeters I think you mean capacitors, not resistors, Elevick.I modded a few of these for use in a HT system. I replaced the stock cap on the tweeter with the same value Auricap, and the inductor on the woofer with a better one. A little Mortite on the woof... |
