Another Super High End Phono Stage! No expense spared...

Looks like your missing a channel, Sachu. Has the HI/LO MC board been made by anyone to purchase?

NO,perryinva,
I have sound in both channels.I accidently lifted one of output trace in PCB,so I have soldered one side output wires underside of PCB.

Regards,
Sachin
 
Omishra,

Nice board.
How about having the inputs and output
connections on the same side?
It is easier to use that kind of layout where the connectors
are located at the back, like the enclosure used by Sachu888.
Here's a pic I found via google, to show what I mean.

Sachu,

A skid sideways. I have never seen AmazonBasics cable before. I looked it up. It looks well made, and inexpensive.
 
I'm still in for a single CNC from Sachu but would like to reserve a spot in line for the "all-in-one" being discussed.

Waiting for feedback from HypnoToad. Sachin & Omishra don't have the S/W needed to create files for PCBs larger than 80X100mm. I'm guessing (SWAG) that a PCB for a combined CNC & SP would need to be about 80X180mm.

Just checked with ExpressPCB. That will handle it but the file format is not the same output you get with Eagle. I believe that would perhaps limit who the board design could be sent to or affect the cost of the boards. I think. But then, what do I know.

Why have them on the same board?

The super simple preamp is only 50mm x 75mm or 2" x 3".

FreePCB can make files as big as you like and outputs gerbers and standard drill files. It takes a little longer to do a design in though but it's very accurate.

It's entirely possible a CNC and SSP "could" be put on a board that's the same size as the CNC IMO.

Yes they are very well made,good for TT use.I had consulted Howard aka Hakaplan before buying.

I can add that SSP to CNC board. In same size of CNC that would make parts crowded/nearby. Are you okay with that?

BTW I will try FreePCB too.

There is only 15 parts to the SSP just need to bunch things up a little. :D The biggest components are the 2.2uf caps.

FreePCB is great, it did crash on me once, so save often, you can create custom components as well which I like.

ExpressPCB is very easy to work with but you are limited to where you can get the PCB's made.

Okay, so I made them together. Look at this.

Same Size: 3.95" X 2.95"

Very nice looking PCB (and appreciate the work you've put into it). Would you be willing to create one of just the SSP for those that already have the CNC and wouldn't need that functionality?
 
Who would I be to disagree with HT???

Yes, VERY nice! Please put me on you list if you get enough for an order.

Thanks for the quick turnaround - - -

Thanks everybody. Still I have two plans -
  1. Plan 1: CNC and SP as separate boards. Because separate SP board may not cost much (2-3 USD per PCB provided more 12 ordered + S&H , more or equal). I am going with this because with CNC phono stage, I am going to use PASS B1 as preamp. So I do not need SP.
  2. Plan 2: For more than 12 takers to this CNC + SP combo manufacture of machine made PCB is feasible. Still it will add cost ~1-2 USD as more holes need to be drilled to same dimension of PCB. For naive DIY enthusiast, it may be too much crowded board to populate. Also keeping unpopulated parts for SP will be wastage & will not look good. I am out of the race of this board due to my use case.
I do not have equipment to measure different of performance due above PCB layouts. I encourage to use plan-1 which gives more flexibility of use and simple to build. Both plans use same components, similar layout and most important no cost advantage in combining together CNC+SP. More or less costs have marginal difference of 1-2 USD.

P. S. I corrected all label at the output. It is midnight so I will check it again.

Thank you. Yes that could be done. Please let me know interest, at least >10 boards. It is really simple preamp to do.

Separate PCB can be made for SS preamp,it will add only $3.
I got the pricing for PCB maker,minimum quantity is 10 PCBs.I can get CNC and SS PCB done @$8,shipping to US $4(approx),so you can have one CNC+one SS preamp in $12 shipped to US.
I received some boards from PCB maker(Passb1 clone,Lightspeed Attunator and Powersupply)

Damn, those are nice. I'd go with the separates (CNC+one SS preamp). I'd be in on the above setup (Passb1 clone,Lightspeed Attunater and Powersupply) as well if you're making those too.
