    but I am curious as to what new chips will be used for the circuitry. I think that I have bought just about every kind of 4136 chip ever made

    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.

    My current two go to tracks for testing soundstage width and depth are:

     

     

    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.

    I've been a fan of Tori Amos since the release of Little Earthquakes in the early 90's.

    Always enjoyed that recording.

     

    Thanks for the recommendation on the EP.

    Finally, I've started on the TX2 Tuner rebuild and have one question - does anyone know anything about the display VFD in the TX2?  I have the part number but can't find anything anywhere about the display - even what firm made it.

    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.

    The film stars Mark Wahlberg, Iko Uwais, John Malkovich, Lauren Cohan (she's really easy on the eyes) and Ronda Rousey.
