  1. Sent it out to the builder. Will post whatever findings he comes up with.
  2. Can I just plug these into the RCAs as a way to short the RCA and do that last final test before sending it off? Or is that a moot point, due to the SS not having any noise? And I should just send it off?
  3. Yup! I kept it! So I will send the amp out soon.
  4. Yes! We're good. I wouldn't respond, if I had enough! I appreciate all the help!
  5. I will test with CW. I will do the Phono thing tonight. It was a GC who did the work, who has electrical experience, but we also fired him, so there is that. Yes, there is a grounding wire that comes from the house and that is hooked up outlet. Yes, it is on a 20amp breaker and I had to switch it off to change the outlet and make it right. No, unfortunately, the breaker situation is pretty scatter and the whole basement is scattered across like 1-2 breakers......which I'm now realizing I wish I would have knwo more now to have it on one circuit.
  6. So, not long after I got the Dynaco( Arrived to me on October 12th), a red spot developed on one of the power tubes ( October 16th), . I replaced that power tube and everything went back to normal. Then, I noticed a teeny tiny bit of noise when they were on the Cornwalls when standing right next to them and then very faint when sitting in the listening position about 8ft away. Once the basement was finished ( I had a more robust electrical outlet installed where I was going to place the stereo equipment https://www.homedepot.com/p/Leviton-20-Amp-Industrial-Grade-Heavy-Duty-Isolated-Ground-Duplex-Outlet-Orange-R71-05362-IGS/100356987) I took the Dynaco down and set it up with the La Scalas ( Around November 15th) and the noise seemed to progress and get louder to the point at which I started asking some questions on here as well as asking questions of to the builder, because it really interfered with the listening experience and seemed to be exacerbated by the addition of the tube per-amp I hooked up to it, which was a brand new build. The builder of the Dynaco has said I should just sent it back to him to have him look it over then fix it, because he thinks it could a bad filter capacitor, but I wanted to make sure I exhaust all options before doing that, given the cost and risk that comes along with shipping.

  7. Yup, for awhile, before I had the LA Scala's, I only ran the Dynaco on the Cornwalls. What I have noticed is that the Cornwalls have more bass, but the La Scalas have way more detail. So after getting the tube problem solved, I may look at ways to increase some of the bass in the LA Scalas, because I think getting that little bit of extra bass, with them, could really create an amazing experience.
  8. I have a set of 1978 Cornwalls, and a set of 1978 LA Scalas. This tube system is running the LA Scalas.
  9. I'm close and can get them if someone wants them. I would be happy to house them until you could come pick them up. Sonically, would these sound any better or worse than the ones I currently have that were manufactured in 1978?
  10. Set the SS up and there isn't any hum. Just had to listen to some tunes! Will make the RCA short here soon and post pictures to make sure its right and retest the tube amp.
  11. I have a set of RCA plugs attached to a cable and could sacrifice one of them for this, given that they're $6. But, once I cut the RCA ends off, do I just strip some of the wire and wrap it around the shield?
  12. Doesn't look like it. Pic attached.
  13. Does Parts express sell those? I really try not to order on Amazon. Don't hate! 😁
  14. Okay, so the dac is a 2 prong only plug. So you want me to plug that into the extension cord then do dac to preamp via rca and then preamp to power amp via RCA. Then see what that sounds like and compare it to amp only via extension cord?
  15. Totally appreciate your help! I just don't know ow what you mean by shorting the inputs. Would that mean, I connect either amp to the speakers with and RCA running out of said amp and then use a screw driver to connect the male end to the shield of the the White RCA plug?
  16. I used an extension cord and an outlet across the room. No change in noise. I put my multimeter on the ACV 200 setting and the put the red on red and black on black terminals on the speaker and it just read 00.0
  17. Yes, just a power amp. It has one set of RCA inputs and 5 ways for the speaker connection. When I did both tests, it was merely amp to speakers connected and amp plugged in. Nothing plugged into the rca inputs of the amp. I do have another SS amp I could plug I to the speakers and outlet. Tube wise, I only have another Pre and Phono.
  18. Yes, both speakers even when its just the power amp hooked to the speakers. Nothing running into it.
  19. I can certainly hear that same sound that I posted sitting across the room where my chairs are at about 8ft away.
  20. Okay, I did the amp, direct to the wall outlet, hooked to the speakers, with nothing running into the amp. I used both the 3 prong and the 2 prong. The sound got louder with the 2 prong. Video attached. 20201202_222311_2_1.mp4
  21. Very good. I will do that right now.
  22. DAC is 2 prong cord. Unbalanced connection? I don't understand your last few questions.
  23. Okay, so I will unplug EVERYTHING from the power strip and then plug JUST the power amp into the power strip with the normal 3 prong plug and see what that does. THEN I will try in the power strip with the 2 prong end to see if anything changes. Is that what you would like me to do?
  24. I double checked and re seated the speaker wires before turning everything on again. After re wiring connecting the wall outlet problem. 😁
  25. Yes, the tester said hot/neu reverse. The Ground light was not on on the power strip before. It now is.
