aaa

there have been a MASS order of 4N 25G silver wire on head-fi.com at about US$1/ft. one guy from singapore bought 100ft.

If there's another MO, maybe some of us can share to buy a few hundred fts.

If there's place to by those linear crystal OFC, I don't mind also

Shall we buy together ? Maybe can bargain a bit

I have been to Koba recently, If I didn't get it wrong, they only have silver coated copper wire in stock.

Heard that silver coated copper made the sound overly bright, maybe this will just right for a HD650 on PPA using OPA627?

Hi bpribadi,

I have a friend that passed me some Kester solder.

The quantity is more than I will ever need.

If you are interested, I can give you one 1/4 KG roll of Ag3/Sn96.5/Cu0.5 for the help you offered everyone.

PM me for contact.

Anyone knows of anywhere to by Silver wire locally?

5N will be best and 4N also can.

need 2-3 meter for my PPA

Your informations are really useful to my PPA project.

Can also let me know where you get the female RCA and female 1/8"?

They look pretty good quality!

may I know where you get your blue ALPS for 20?

getting one for my PPA clone.

(Board layout has been modified on Aug 16)

 

may I know what software you used to draw this?

It looks much easier to design and edit with such software than with paper and pen.

Thanks!

Thanks for the service!

I want to order:

16 X Gold plated DIP8 socket

pls let me know how to make my payment

yea... digi is making them now. will arrive end of this month.

i just got shock seeing the price!! WOW...imagine that USD1=S$1.72, still need to add S$2 per USD1...

Hehe..he is really drunk ....need

Well the post office is not going to charge me 1.72 for exchange rate.

The shipping is not free either.

In fact I wish that there's someone else who can offer this service so that I don't have to go through the trouble of ordering oversea myself.

Any way, since the adaptor is available locally, there's no longer any problem...

I think I will order from tangentsoft first, since nothing can starting b4 getting the PCB.

Considering cost, risk and trouble involved, I'm thinking of charging S$2 per US$1 plus S$4/order for processing and mailing through local registered mail, 100% pre-payment by ATM-transfer, money order or mail-in cash (at your own risk). Do you all think this is too much to ask?

that is $6/piece for the adaptor or $36 for the PPA board, excluding $4 processing.

any one intersted at the above condition please add to the list below

Adaptor, SO-8 chip straight to DIP-8, with no pinout change. BrownDog part #970601. $6/piece

#name #quantity

Adaptor, two single-channel SO-8 op-amps to a dual DIP-8 pinout. BrownDog part #020302. $6/piece

#name #quantity

PPA PCB $36/board

#name #quantity

after add your name to the list please PM me your real name contact number, mailing address, payment method etc.

Any one building PPA? maybe can buy parts together to lower cost and cut the trouble.

parts that can mass order are

ALPS RK27112A, 50K potentiometer, smooth Shaft

- Taiwanese THLaudio charge less than S$20 a piece

Vishay RN55D resistor

- Federal (are they the distributor of Farnell and RS?) only sell in 100s.

anyone have any other alt in mind?

PPA PCB Ver 1.1

buy from tangentsoft

Wima MKS-2 6.8µF/50V

AD8610AR on adapter

many may want these from tangentsoft

OPA627AP, OPA637AP

remember someone on the forum can contact TI china for S$20 a piece, but he cannot buy everytime one forumer wants a few piece. So may be all whose are interested can getter and ask that friend to buy it mass one time and for all.

in fact all parts will benifit from group buy.

Although the no. of ppl interested in building PPA might be quite few due to the high cost, it will be quite a bit of saving even if the crowd size is only 3-4. (shipping cost will decrease by 75% if 4 guys share it)
