I did and still got the latest noise that I posted just a bit ago.

Another pic of the power strip, nothing special.

You guys are rad by the way! I really appreciate your help!!!!!

You didn't miss it. Here is a pic of the power strip.

The sound I took is through the speaker. The Horn section.

What do you mean by this? 🙂

Okay, so I got an outlet tester and it appears the the outlet was wired wrong, so the polarity was switched. I fixed that and it tests correct now. Then I plugged it in like normal into the power strip, still a noise, but different, then I plugged into both the wall and the power strip with the outlet adapter and still a noise, but different. Attached is a video of the new noise in the speakers. 20201202_162146_1_1_1_1_1.mp4

I haven't. What is the best way to do that?

It is in both channels. There are 4 power tubes, and 2 driver tubes that all have mates. I can send you a photo of the amp if you want? I have also reached out to the builder to see what they say too.

Yes, I have one of these. So, put this on the end of the amp plug and plug directly into the wall outlet or the power strip? Right now everything is plugged into the power strip. Thanks!

All cords and outlets are 3 prong. Yes, all plugged into the same outlet.

So I did ground the RCA to itself and hum in both speakers. I also took the RCAs off altogether, just speaker wire to amp and there is still a hum.

Yes, tubes are exactly as seller suggested.

Thanks! Yes, I have to give a ton of Kudos to Holger at Erhard Audio. He just spent 20min with me on the phone walking through a couple ways to chase down the issue, including shorting the Power amp, which when done, makes the noise LOUDER. : / I already had new power and rectifier tubes on the way, which he suggested changing them out will be the next step in seeing what's up. Any other words of advice on troubleshooting the problem?

Here is a super short video. Due to the 2mb limit, its harder to post anything longer. 20201130_223857_1_1_1.mp4

So, there was a teensy hum when I was using the Schiit sys with the Will Vincent St-70 and was not audible during a song, only in between or when no music was on. but now that hum is WAY louder with the Aretha in all areas.

I will see if I can post a short video. That might be the easiest way to hear it.

Woot! Got the new Erhard Aretha Pre......got it hooked up and ready to go.....then lots of noise in the La Scalas.....and what I mean about that is I heard a feedback noise in the speakers when there is no music playing and when there are quiet parts of music....is this to be expected? Or am I doing something incorrectly? Here is the chain: laptop, hooked to Music Fidelity V-Dac, hooked to Aretha Pre amp, hooked to Will Vincent ST-70 hooked to the La Scals via 10awg silver coated copper wires bare end. The build quality of these units are great! Iooks rad too, and when I dont hear the "feedback" sound it sounds lovely. So, again new to tubes and want to know if this is what comes with the territory? Thanks!

Alnico is what I meant to type

Very cool. Does that make them Albina? Given their year?

Jeff. This is VERY HELPFUL! I too thought this was a good deal at $500, so that is why I inquired. I asked him for dimensions and weight and he has gone silent, so I'm thinking it won't work out. If you pay FedEX to pack it, and insure it for the full value, they have done a great job for me, because it seems like they are ramping up efforts to cut down on claims. Thanks again for your help! And I would certainly be open to chatting about Monoblocks if you want. We can message back and forth about them. My plan was to budget to buy something in about a year, and then this came up, which looked like a sweet deal!

Thanks! He is asking $500 for them and then whatever the cost of shipping would be.

He is hesitant to ship them due to size and weight, but im going to see what it costs and see if I can just have him bring them to FedEx for them to pack and ship them. Just so I dont go crazy in the red on these. What does everybody think an approximate value is on theses?

I'm going to talk with him tomorrow, but it sounds like he doesnt want to ship it. 😔 So, unless I can find someone in the Raleigh/Durham area to pick it up for me and ship it, I might be out the game......😬
