| Linlai E 6sn7 tubes danmar123 134 posts 05-22-2022 at 03:22pm @bugredmachine Glad you received the tubes today, there has to be something going on with the pre-amp. Just a shame you have to go thru all of bull for them you work. Remember I only put a total of 2 ... | |
| Linlai E 6sn7 tubes Dan sent back my first pair. They are still noisy. Too noisy for me to play. I'll try replacing my resistor in the preamp this week and try them again to see if that affects them, but it shouldn't. | |
| Don Sachs Owners Thread Forgot to mention; running a 5852 tube is okay IF you have the proper resistor in place. My PCB has the old 1 ohm resistor and that is too high for the higher current 5852. You need a .1 to .22 ohm, 1 or 2 watt to be able to run both 6X5 and 5852 ... | |
| Don Sachs Owners Thread Keep in mind the ground tab on the preamp is the same as the ground on your IEC inlet and all the outer shells of every audio connector on the unit. Essentially they are all chassis ground and the electrical ground. So be careful to not create a g... | |
| Linlai E 6sn7 tubes Received my replacement pair from China and FINALLY, they are almost completely hiss-free. Magnitudes better than the other 2 pairs I have tried. While I was getting 8 inches of hiss on all my other tubes, these are about 20 inches, evenly so lef... | |
| Linlai E 6sn7 tubes I think the 5852 tube messed up that circuit, which happened right before the Linlai's showed up. I had another 6X5 do the same tonight so I think when everything warms up the damaged component is flaking out. Perhaps the Linlai's irritate that co... | |
| Linlai E 6sn7 tubes I'm not having issues with any other tubes. Just the Linlais. Tomorrow I will measure the pin diameters and compare. Then take the preamp apart and check for solder joint cracks. Then I may force the tubes in without the lid attached and support... | |
| Linlai E 6sn7 tubes I finally saw the link above and ordered 4 extenders. Maybe the tubes are tight and not inserting all the way. We'll try that workaround when they arrive. | |
| Linlai E 6sn7 tubes Don does not buy tubes from Viva. I am not sure why my preamp does not like these tubes. Don assures me it is not the preamp. He gets the occasional bad tube. Maybe the third set of tubes will be better.🙄 I sent a note to Viva and asked them if ... | |
| Linlai E 6sn7 tubes Don told me to let the tubes run for 20 hours. So far in 8 hours, no change. One tube is 10x louder than the other. I can hear it outside the room. Swapped the cables left to right and the higher noise tracks the tube. The lower noise one is still... | |
| Linlai E 6sn7 tubes My US-sourced pair hiss as well. Â Where are you buying your tubes? I bought the 2nd set from VivaTubes. | |
| Linlai E 6sn7 tubes My owner's manual for my Sachs states 5852 is an approved tube, just to let the pre warm up first. But after just 20 minutes the tube started flaking out so I powered down immediately and will send it back to the Tubedepot with free return shippin... | |
| Linlai E 6sn7 tubes I'm having bad luck with tubes. The Bendix 5852 burned up on me at 20 minutes of use last night. You've never seen a big man move so fast running for the power buttons. | |
| Don Sachs Owners Thread Jumping the shark to a new topic, I did add a Purple fuse in the spring and it made a very nice improvement. Even more so when I added the contact treatment from High Fidelity. I keep squeezing this preamp and it keeps giving me more. |
