Whats this CNC Phonostage all about?

I regard my Musical Fidelity V-LPS as a 'bargain basement' phono stage, and it cost quite a lot more than is being spoken of here. Suddenly even I am interested in this one!

I've read some of the stuff here. Will talk to Capt Rajesh about it when we meet next which is planned to be soon.

You can also listen it at Murli N's place.I think Capt has not built it.

Guys, I think we need to encourage Jay to build this CNC phono preamp by himself. I believe he has what it takes to be a good DIYer - Curiosity.

I've noticed that since of late, he's asked loads of pertinant questions on various topics across the forum. That clearly shows his interest to learn and more importantly, his trust in all of us.

Jay, once you get over the initial butterflies in the stomach, you can definitely become a good DIYer. I started soldering when I was around 4 years old so its not big deal, you can do some simple practice steps and get the heck of it.

The CNC preamp is a very simple one and the printed circuit boards (PCBs) designed by Sachin and Omishra are fantastic and extremely easy to use. You should give it a try just for the sake of learning, atleast.

Being in the world of hi-fi and not being a DIYer has tonnes of disadvantages. My father always used to say, "never feed a guy with fish, teach him how to fish and he'll never be hungry for the rest of his life".

All the very best.

Thanks for your kind words.

Its not that I do not know how to solder as have done lot of this during my school practical days.But I do not wish to take a chance with something which can affect my highend audio systems as I am not a Technical person.My Guru in highend audio always tells me "leave it to the doctor to cure the patient instead of fideling with it and spoiling things".Thats a reason I am a bit sceptical in sourcing this as it will come in the raw format and I need to get it set it up which I won't be too comfortable in doing at.

building is one thing and fiddling, meddling and experimenting is another :ohyeah:

a phonostage is a harmless addition and cannot cause any damage, really!!
 
There are levels of fiddling and meddling.

Most of us probably do it outside the cases, but it takes the knowledgeable and experienced to venture with their tools inside. There, for instance, I do not go. (or, at least, only for a look around :O ).

But it would be lovely to look at a case and think that, not only did one meddle inside it, but one actually built it!
 
Jay,

I strongly recommend you built one of you own. I am in 101% agreement with Ruben said. The gratification you get is priceless.

Regarding the Cnc pcb from Sachin and Om, it's extremely simple to built and guaranteed to work 100%. The sound is heavenly.

I took the soldering iron after 15 years to built this one. It took me 5 hours to built my first Cnc :). Then I got so excited with DIY, I ended up building a power supply, pass b1 per amp, 5 channel source selector and one more Cnc and housed them all in a beautiful cabinet. All the kits were provided by Sachin and cabinet, cabinet accessories and transformer for power supply was provided by Raghu. Also I got lots of help from Om and other FMs in the forum.

My pass b1 pre is under testing and let me tell you that it's one he'll of a performer. I fell so happy and proud that I built it :)

Off topic : DIY audio is a wonderful hobby to start if you are already sick with what you are doing as your day job. I am a s/w engineer who is already sick of what I am doing for a living :lol:

Thanks,
John.

.... :clapping:

Music, DIY, Tweaking my TT or Setup help me overcome office work pressure

Almost same boat

@ Jay .... basically you may get help from any FM member to get a CNC built for yourself ....

there are two types of circuits ... one for MC cartridges and other for MM cartridges

i got both from sachin ... and both are great sounding

i believe its worth experimenting and finding out whats different about it, that no one is willing to rate it anything less than 5 star

All the Best

DIY Therapy.

Not electronics, but... I used to make jewellery as a hobby. One day, after spending several hours (overnight, actually!) working at my bench, it occurred to me that, for all that time, I had not once thought about myself or personal problems. A wonderful side effect to acquiring a skill!

But, I continue to find electrical soldering really really hard. I keep telling myself that it just needs practice...

Yes, Thad its all about practice. One way to do some soldering practice is to get a general purpose PCB and buy some cheap resistors and caps and keep soldering them :D

Get one of these boards

General Purpose PCB (10.4cm x 8.4cm)

And get a bunch of resistors and ceramic capacitors :)

1K (SMD)

33pf

I think you can get all the above online with in Rs 150/-

My 2 cents :).

Thanks,
John.
 
Ok................I think I have to take the plunge :-)

Sachin..please tell me once I order CNC what are you going to send me? And after I receive that what am I supposed to buy/source extra and how do I compile?

+100 to above.

Go for it buddy. I will help you with the tools and other components/accessories you would need. To start with this is what you would need

1. Soldering iron / Soldering station. Depending on your budget, you can choose either one of them. I got my self a Soldering station.

2. Solder and Soldering paste. I use 60/40 22AWG solder. Also get de-soldering wick and a de-soldering gun.

3. Wire cutter, Small Player, Forceps.

4. DMM (Digital Multi Meter). You can start with a simple one that cost around 300-500. You can also get a more fancy one if budget is not a constraint :)

5. 22-24 AWG interconnect wires. This is useful to connect external components like RCA jacks, DPDT switch and battery pack to the main circuit

6. 2 pairs of RCA jacks. I will recommend gold plated ones from MX electronics

7. 1 Speaker terminal. This is for connecting the TT ground. You can only buy them as pairs only.

8. Screwdriver kit

9. Magnifying glass and a table lamp is also recommended.

10. A small scissors and a knife.

You can get all the above online / local stationary shops :). Here are the sites I use the most

1. The online store for robotics and embedded systems fanatics! Buy robot kits, components, motor drivers, omni wheels, microcontroller boards, sensors, Quadrotor BLDC motors, batteries and chargers, embedded systems development tools, Robotic arm.

2. MX MDR ELECTRONICS & MX ELECTRONICS & HDMI & CCTV CAMERA & DVR & SDI ACCESSORIES & VGA ; DVI & APPLE ACCESSORIES & CABLES & CONNECTORS & HOME THEATER CABLES & PRO-AUDIO / STUDIO ACCESSORIES & FIBER OPTICS & CABLE MANAGEMENT & CABLE ORGANISER & VIDEO - I use this site for getting all connectors and jacks.

Google/Youtube for some soldering tutorial videos and you will get plenty of them online. Worth a watch :).

I will let you know if I think about any other stuff.

Good luck buddy :).

Thanks,
John.
