IMO the above could be an individual choice/optional.

Hi Sachin,

In the morning I thought I saw your post stating that you are awaiting confirmation from me regarding the PCBs. I wanted to reply to that post but it went missing!! Are posts getting deleted here?:annoyed:

Hi Santosh,
Only soldering is required for this project,no worries.

Thats good, eagerly waiting for this to kick start.

Hi, Sachin, sending you a PM.
Hey Santhosh, George knows someone who is a professional electronics guy. This must be a 15 minute job for him.

Yup Philip is very good.

But I would like to try this on my own. I actually feel left out when you guys talk tech stuff about rating of resistors, capacitors etc but not this time around. I am looking forward to the learning experience.

Hi Santosh,

PL follow this guide for soldering

This is my thought which could reduce cost further shipping-wise/quality-wise. Anyway I am open for what everybody decides. Please give a thought on this.

Must have:



Can be procured locally:
Capacitors (Generic common values):

Resistors(Generic common values):


Optional/Non critical (if anybody has different plans to power up/integrate):

Hi,

Thanks for ur breakup. I was also thinking on the same line but didn't get time to visit market meanwhile to check availability of the parts. Also for the first time assembly, using Digikey parts will give extra bit of confidence as it is already done by Sachin using same materials.

Is 'Keltron' caps are as good as 'Panasonic'? Bcos in Calcutta it's very highly recommended. What r the other good brands fr caps & resistors available in India?

Thanks & brgds

Bhaskar

 

[captrajesh]

I am waiting for CaptRajesh for PCB confirmation, we can order above components once we get the confirmation on PCB.

Hi Sachin, it was nice interacting with you over telephone yesterday. Hope there is some progress of the PCB part.

Is 'Keltron' caps are as good as 'Panasonic'

Yes I'm, told they are; I had recently restored a vintage Luxman amp and all the old caps in the tone control boards were replaced with Keltron ones. The amp sounds very good now.

Thanks Capt.

I have registered on PCb website but not able to logged in.I am going to local PCB manufacturing units will update in the evening.

PCB update

Hi all,

Today I went to a local PCB manufacturing unit.They have shown me some samples,which were at par with my CNC pcb.The minimum quantity was 10 so I ordered. The cost of each PCB is INR 70-75 including initial making cahrges and tax.He promised to deliver PCB's on Friday.

Regards,

Sachin

Hi Sachin

I'm still in for this, but by when would you need the money from my end, and what is the total cost to me?

Also, if someone in Mumbai knows anyone who can help me to put this together, I would be very grateful. I am quite bad at DIY stuff, and I don't want to break a part or something and ruin the whole project! Although it seems like a really fun thing to try out, I don't want to mess it up :-0

Cheers

Tek

I will PM you regarding money.Total cost would be in between 2500-3000 depending upon no of members for group buy and custom duty.It will include all parts and PCB, minus case.I have put my PCB in a wooden Jewelry box which I bought it from a handicraft exhibition in RS 200.You can contact Omishra as he offered building this kit for you.

Sachin,

As I mentioned, please think on these item for local procurement at least. Shipping charge of 9V alkaline battery and local RCA connectors can be saved.

Quality won't matter for these except item 10 which is not gold plated. If required I can purchase these for everybody. see item wise max price here -
7,8 - Rs 8 each/-
10 - Rs 5 each
11 - Rs 1 each
26 - Rs 5 each
27 - Rs 140 x 2 , 9V alkaline batteries are locally available from Duracell and Energizer. No point in importing and increasing weight of international shipment.
28 - Rs 25 Max (worst case)

also the item I told can be procured locally - wont cost more than 100 Rs. Still I say caps and semiconductors are okay if imported. Let me know.
Also I never charged in custom duty due to the fact that I always kept requirement list short.

Sure, Why not? I can go to market on Wednesday and do the shopping. Let me know total requirement. Then you can order remaining. What do you say?

I really miss Bangalore SP road. Vishal Electronics used to have all these values one stop. Any Bangalorian can still help.

Guys add me also to the list.
I'd love a phono stage since my AVR cant take phono inputs.

I am in the same boat as Tek though.
Mr. Mishra, if its fine with you, do you mind putting this together for me as well? Would be much obliged.

How do we go about transferring the money over to you Sachin?
