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......😬

Cool. I'm just hoping they are open to shipping......

Ymtc? I don't know a ton about these things being new to tubes, but since reading through this I just sent the seller a message saying I'd like to buy them.

Very cool. It sounds like the owner of this built it themselves from Kevis 32b monoblock spec. Yeah, I'm not going to try and make more power, givin the sensitivity of the speakers. 32B_monoblock_PP_amplifier.pdf

Hi! I came across a set of monoblocks from K&K Audio. Here is some info: Two Monoblock vacuum tube amplifiers. Push pull design using transformer coupling between all stages (input, inter-stage, output). Estimated 7 watts per amplifier. Can be modified for more power. Lundahl interstage transformers RCA and XLR input connectors. Output transformer is a custom design rated at 90 watts. Power Supply transformer also a custom design of excellent quality. Tube complement (Russian NOS): Output: GU50 Driver: 6Pi3C/6N3C (very similar to the 6L6GC) input: 6N6p / 6H6pi Driver stage operating point is set with current sources. Output stage operating point is set with current sinks. (Stable, reliable, easy to set.) Has a custom designed soft start circuit. Extra OP tube sockets and extra tubes. I'm wanting a set of monoblocks and this fits the budget, but I dont know a ton about what they are selling, so I wanted to gather some thoughts here. I would run these with my La Scalas and a Erhard Audio Pre and Phono. Thanks for any knowledge you can drop on me here!

Yeah, its pretty cool. I'm not allowed to buy any more speakers for at least a year. 🤣 But maybe I could setup my la scalas as corners and use one of my cornwalls as a center. Self imposed sanction.

On the resonating you mention. Is that a concern when listening to the La Scalas at low to medium sound levels? I've seen there are a couple places that sell braces to help stop the resonate, but wasn't sure if it really was an issue when not cranking them.

Are there differences between these La Scalas and a normal La Scala that commands a higher price?

Big old price drop! https://portland.craigslist.org/clk/ele/d/vancouver-vintage-1980s-klipsch-lascala/7225193291.html Still too expensive I think.

Just talked to this guys and he is super nice. He really wants to sell these locally and I think he would work someone a better than $2k deal if sold locally. His dad was a music teach and had all kinds of nice audio gear. We wants to sell all 3 Chorus ii speakers together. https://denver.craigslist.org/ele/d/westminster-klipsch-chorus-ii-speakers/7226221422.html Not affiliated, just trying to make sure these go to someone who will appreciate them!

I can second that. I have one of the Will Vincet ST-70 and its fantastic. He has one upbon Audiogon right now for sale.

From regular LA Scalas that is.
