If the DC is high yet reasonable (under 60mV or so), check the input AC coupling capacitors for shorts. Many models this is 470uF, but others have 220uF. For which model? The m1.5t does not have a thump fix bulletin. It's one of only a few models (m400 series) that does not have a power switch. It's "instant on" as soon as it's plugged in.

welcome!

I ripped most of my CDs onto a Mac years ago. At that time, no special software was required, ripping was part of the "iTunes" application. My 2010 Mac also had an optical drive. Most (all?) Macs have not had an optical drive for many years .... maybe you have an external one? Additionally, iTunes is a thing of the past, but I would think the Apple Music app has ripping capability? Apple Music has fully replaced iTunes.

No

I always use blue tape on the faces then I'm using my crappy tools to drill holes in metal. thanks for the confirmation that I'm doing that part the correct way.

I understand this statement completely. Strongly agree, I have the same proclivities. The pictures of your work tell me all I need to know. I enjoy it as well. I'm just tinkering right now. After adding the preamp/volume to my C-9, I was very satisfied .... but I wanted more. I wanted to be able to remote control the switching. It's something that's certainly do-able in the current C-9. After some thought, I realized that it was the wrong approach. Why not just keep the electrical design but redo the mechanics? I needed a project ..... keeps the brain from turning to sawdust. Like I said ... just tinkering. Still have yet to pull the trigger on it. I'm really looking forward to the new SH implementation from Bob. One of those will be in my rack.

A new SH stand-alone product should be 95% surface mount components. It's 2023. Building surface mount in volumes is the way to go. Not sure how the tube buffer would fit in as I know jack about what that circuit needs to look like. I actually have a layout for a surface mount C-9. Hope to make it fully remote controllable. It's a 4x4in pc board. Includes the power supply and 2 input preamp. Only the power supply caps and the 22uF coupling caps are thru-hole. Remote receiver is a separate board, transformer is separate. I was bored a few weeks back and it was raining so I laid it out in a day or so.... tweaked it here and there. Mostly did it for fun and to kill a few hours. I'm really curious if adding a ground plane quiets the annoying hiss when SH is enabled. This might just be a by-product of the comb filters, but I'm still curious. I have yet to pull the trigger on the boards. Building this by hand with mostly 0603 SMD components will be a huge challenge. I've built a number of surface mount boards by hand, but the component count was much less than what would be required for this project.

While I guess it's important for a unit like this to share styling with the other products, it will be purchased by people who have no intention of purchasing the amp or preamp. I'd guess this was the same story for the original C-9? Many were sold to people who did not buy Carver preamps? Like the C-9 it should fit in a 1U rack space. Rack mount ears would be a simple option, no need for a dedicated rack mount face. Tubes seem completely unnecessary, and meters on a pre-amp make no sense and will only drive up costs. Make it simple. The suggested switching options sound good.

This is a really good idea. I wish I knew these existed to match the connector spacing. I spaced RCA without measuring the actual unit, only reviewing pics. Can't imagine my spacing lines up. It was the intent that the front of MYLP1 would face mount due to pots, but the RCA would be panel mpunt and wired. IN that case, best to know this spacing ..... or you could make them yourself. Awesome tweak on the DQLP1. Simple and effective.

My history with the DQLP1. Will and I have had several DQLP1 discussions for a few years now. I'm not unhappy with my setup with has a miniDSP doing the job of actively splitting out the LF and HF signals. I've threatened a DQLP1 purchase a few times, but never pulled the trigger. This was an interesting project. With the exception of a new power supply and updated components, the original schematic was pretty much copied with the exception of splitting out the switch functions. The original unit has one switch per side which turns off the LF signal at the same time bypassing the HF filter cap, sending full signal to the mains. From my side of the design, I wanted the finished product to fit in a 1U space. Found some nice transformers that allowed this to happen, while also being board mounted. Mistakes: The frequency adjust requires a triple ganged pot. Will found some quad ganged that would do the trick. Based on the non-linearity of the DQLP1 frequency dial, I assumed these were audio taper. As I tested the first unit, I realized this was a mistake. Not all that bad except that 100K ohm linear quad ganged pots were not available. I decided to go with 50kohm. This meant that the caps in the LP filter sections all had to double. Note the doubling up of the caps (orange, green, and red pairs). I had allowed an extra spot for a common modification to the original DQLP1. Build notes: Build was easy. The concept of the enclosure was simple, the implementation was considerable effort. I used a blank 1u plate for front and rear. I used solid cherry sides to pull everything together. Top and bottom were cut out of an old cover. I have minimal tools, especially for metal work. Each wood side has 7 holes with brass inserts. Next Mouser order, I need a few RCA. This worked well on the bench. I have yet to use it in my office setup. My initial thought was to A/B using 2 amps, one with the miniDSP and one with the LP1. I had all of the pieces to do this but sold an amp last week. OCCD has mostly left me, for which I am relieved. The LP1 50k ganged pots have a center detent. This corresponds to 70Hz, which works well for me. Interestingly enough, When I plugged the miniDSP into the computer, I realized I had it set to 70Hz. I know what all of the knobs do. Everything is mirrored around the center, the inside pots are L and R freq adjust, the end pots are L and R level adjust, middle offer some equalization at low frequency.

I think this recording ,especially the title track, brings out the best in any system. I've been hard pressed to hear it sound anything other than exceptional on all kinds of configs.

Always enjoyed that recording. Thanks for the recommendation on the EP.

Welcome. I have a parts TX-2. I think the display was fine before I started taking other parts and realized I would never put it back together as a functional unit. PM me with your details (address) and I'll get it out to you when I have a chance ... provided it's in one piece.

Wow - that will do! Welcome.

I almost watched this last night as well ...... but then I saw Mark Wahlberg ............ ughhhh

Is this some type of Canukstan dialect? LOL. Kidding - Welcome!

Since this is a Carver site, and Carver's most popular preamp is a C-1, I think you really need to clarify what you are selling here as to eliminate confusion. Is it a Carver C-1 or a Soundstream C-1? Thanks.
