Go contact Alvin, he used to sell diy stuff here. Think he might have a few sets of RA1 PCB sets left. http://www.sgheadphones.net/index.php?showuser=4099

It's all in here bro. http://tangentsoft.net/audio/cmoy-tutorial...layout-0150.pdf

Wah, u damn fast leh, I haven't even got time to order the parts yet. The ones I've made so far are in plastic and cheap, about 15-20 SGD. BTW, guy with the laser cut services only accepts cdr files(corel draw). Just a tip, it's better to print it out on paper first and cut out the holes, test the template before sending it for cut. I had to edit AMB's dimensions a bit here and there to get the y1 template to fit proper the last time. I got no sources for metal plates yet, really hoping someone would throw me a bone here on this....

Sure Not a prob. Btw, I will be out of the country from 13-21 of this mth.

Haha! I don't mind man, with the shipping costs saved, u deserve that plate of chicken rice

Nice! Thanks for everything, Heady!

I hope so too, for all our sake

Prices yet to be confirmed lah, but a set made out of acrylic is estimated to be around $20 (hopefully less). Those interested please copy the list from doubletaps post and add yourself to it yah? It'll make my job in keeping track of who is interested alot easier. Thanks!

Hi guys, just started an interest check for face plates. If u're interested, just make your way to the classifieds and add your name to the list. http://www.sgheadphones.net/index.php?show...=0entry119150 I'll see if I can get this done in aluminium this time round but no promises yah?

Hi all, for now this is gonna be an interest check, which will be updated into a group buy later on. Prices are not confirmed yet as we have yet to perform the following. Material used will probably be acrylic again, will try to get aluminium ones done if possible. 1. Build Y2 2. Make sure paper templates fits casing. 3. Contact contractor for quotes. Payment will be by bank transfer. Will update as we go along, don't be surprise if this drags for months as I'll be quite busy in the future. Just bear with me yah? For those who are interested just copy the list below and add your name to it. Cheers! Y2 face plate group buy participants 1. mouz - 1 set 25/10/09: Setup of group buy cum interest check. 26/10/09: Acrylic face plates estimated to be less than $20 but yet to be confirmed.

Should be able to hit 10 lah, I just roped in another guy to join the y2 grp buy. Now just wait for his response

Hi Jojo, Heady's pretty strict about discussions in sales thread. You might wanna ask questions here. http://www.sgheadphones.net/index.php?showtopic=10166

Hi Heady, will take one set of y1 and one set of y2, thanks!

Haha, dont blame you lah. I'm still sitting on the fence on whether I should get another y1 PCB to prevent dismantling my current one. Moolah kinda tight too

Thanks for the heads up! U using the old y1 with the y2?

No prob Blipp, btw, u're right about the AD8656 and the jumpers. Just noticed that AMB has just updated his site. Will update the BOM, cheers!

If you're talking about stuff from farnell or mouser, don't think it's included in this group buy. It's only stuff from AMB i think (PCB and some other parts). Heady, can confirm this one? I did a group buy for stuff from mouser for Y1 parts for some of the guys here. It's very time consuming and quite a nightmare making sure everyone gets the correct amount of parts. Doubt I'll wanna do it again. Probably would only do it just to make up the amount to get free delivery from them though.

Nope that's only the parts for y2 with no PCB. Throw in the y1 to make it complete would be about another 100 odd I think. Madwolf, doubt there will be a complete BOM available. Any help in this area would be very much appreciated though.

Ok guys, here's what I can dig out. As you can see I got most of the stuff from mouser as they got most of the parts. Total cost for items below is about $121.42 without the stuff from AMB. Suggest maybe try to pair up in groups of 2 to get their free delivery here.

Haha yah, but for my case time and budget constraint lah. So no choice gotta take short cuts

Oh yes! count me in. Heady, feel free to contact me if you need help in anything I'll help with the face plates as usual too. BTW, tot you could break open the Y1 and use it with the Y2 board too right?

Guys, forgot to update, the guy who did the face plates waived material cost. So the cost of each face plate is now $15. So to those who already collected, please feel free to contact me for a refund. Sorry for any inconvenience caused.

Face plates are in, collection can be arranged anywhere along the MRT line between Jurong East and Tanah Merah MRT, preferably after 520 and before 620. Thanks! Listening to Mozart Piano concerto No.5 with it now. To describe it, I'd say it's smooth, lush and relaxing to listen to.

this sounds interesting, how many watts and roughly how much?

I think someone managed to find a pair but he paid alot more than what its worth though (needed to import from overseas). I was thinking of building this too but gave up on the idea til I happen to come across a good deal on it.
