Mini group buy of KGSSHV PCB boards


Recommended Posts

Hi:

 

I am organizing a mini group buy of HGSSHV PCB boards. I intend to move very fast so please read this post carefully if you are interested.

 

I'll be using the kgsshvampv16mini.zip for the amp boards and kgsshvpsminifinalstn9360.zip for the PSU boards. The amp boards are the one-board-per-channel, off-board heatsink version. Both amp and PSU boards have provisions for current production parts. See here for the Gerber files and the KGSSHV thread for more information.

 

I plan to use SeeedStudio to fabricate the PCB boards. The boards will be 2 layer, 1.6mm thickness, 2oz copper, HASL surface finish and standard green color PCB. Each set of the boards includes 2 amp and 1 PSU boards.

 

I call this a mini GB for a reason; I only intend to make either 5 or 10 sets of the boards. I am keeping 2 sets myself so I am looking for a maximum of 3 to 8 participants.

 

If we get 5 sets made, the cost of each set is $50 USD, if we get 10 sets made the cost per set drops to $33 USD. This amount does not include PayPal fee and shipping cost (from me to you).

 

SeeedStudio is having a free-shipping special for orders over $150 but orders need to be placed before Feb. 25. If we qualify for this special, per set cost will be reduced by about $5.  Orders won’t be shipped till after Feb. 26 due to the Chinese New Year Holiday.

 

I have used SeeedStudio for my SuSy Dynalo PCBs and was happy with the outcome. You can read my posts in the Multiamp/Dynalo MK II thread. The KGSSHV, of course, operates at much much higher voltage so participate in this GB at your own risk. You should read the KGSSHV thread before making your decision.

 

Here is how I plan to organize this mini GB (I am a DIY hobbyist and have never organized a GB so I am sure I will miss some logistic details. I apologize ahead of time.):

 

1.   Please respond to this thread with your firm commitment. If we have more commitments than can be accommodated, inclusion will be based on a first-come-first-serve basis (FCFS).

2.   I will close the GB by 8pm central time Friday, Feb. 20 or when we reach the 3 or 8 sets commitments, whichever comes first. 

3.   At the close of the GB, I will PM each participant who is included in the GB with a confirmation and my PayPal account information. Firm commitment that did not get included in the GB will be put on a sequenced waiting list, again, FCFS.

4.   The GB participants that receive my confirmation PM need to send $30 USD to my PayPal account by 8pm central time, Monday, Feb. 23 for down payment and confirmation. I can then hopefully send in the order in time for the free-shipping special.

5.   GB participants that do not send me the PayPal payment by 8pm central time Monday, Feb. 23, are assumed to have withdrawn from the GB. The vacant spot will be offered to the next person(s) on the waiting list.

6.   When I received the PCB boards from SeeedStudio, I will PM each of the participants with additional amount to cover the remaining PCB cost, PayPal fee and shipping cost to you. I will use your PayPal shipping address to calculate the shipping cost and it is where I will ship the boards to. Please PM me if you want your boards shipped to other address.

7.   The board set will be sent when I receive the PayPal payment stated in 6.

8.   If I do not receive enough commitment by Friday, Feb. 20, I will likely abandon the GB. We’’ll have play by the ear if this happens.

 

Please let me know if I missed something.

 

I’ve been reading the KGSSHV thread and am very excited about the prospective of joining the Stax Mafia. Hope this will be a fun and exciting project for all of us.

 

Best!

 

Michael

I'll vouch for Michael as someone who you can trust in this GB. I just worked a deal with him for a pair of Multiamp boards, run by the same board house and identical process, and they are very nice PCBs. Michael is a pleasure to deal with, so if you want a set of KGSSHV boards, this would be a good way to get them.

Wow! Thanks guys for your quick responses. This is going way faster than I expected. I have also received PM for boards as well.

I am expanding the volume to 15 sets and closing the GB now. That means everyone posted in this thread is included.

I will follow up with additional details soon!

Fuck me my head is ringing, long night of drinking....

 

How small is the new mini offboards compared to the older rev 0.4/0.6 offboards?

 

So a set is 2 offboard (1 for each channel) and 1 mini ps board, am I right?

 

If so I'm in for 2 sets. But I'am open to onboard minis if a GB for it ever happens in the future.

One set is 2 offboard amp PCBs (1 per channel) and 1 PSU PCB (see my first post).

 

Below is the rough dimension of the boards. I cannot be certain - waiting for confirmation on the kgsshv thread.

 

kgsshvampv16mini (amp): 182mm x 86mm, kgsshvpsminifinalstn9360 (PSU): 176mm x 167mm

 

If someone has this information please confirm or correct me.

 

DefQon, are you still in for two sets? (my bad, I had previously miscalculated number of participants)

This GB is officially closed. Thanks all for your interest, quick responses and participation. Anyone post with their interest for the board set from this point on will be put on the waiting list - please refer to the first post in this thread.

 

I have good news for those participating in this GB. Since the GB was expanded and we will now be ordering 15 sets, the price per set is dropped to $23 USD before shipping from SeeedStudio. Since we should qualify for the free shipping from SeeedStudio (would have been another $63+), the only additional cost for the GB participants will be shipping cost from me to you and the PayPal fee.

 

For comparison, it would have been $43 USD per set if only 5 sets of boards were ordered.

 

Here is the list of GB participants:

 

mypasswordis (2 sets), iwik, johnwmclean, chinsettawong, insanity, eggil, GeorgeP, kingofsnake, ChrisX, DefQon (2 sets).

 

I will PM all of you with confirmation and my PayPal account. I need to figure out the proper amount for your down payment to me now that the per set price has dropped. This amount will be stated in my PM to you.

 

If no one has objection, I like to move up the timetable and ask that you PayPal me the down payment by end of day Saturday, Feb 21 so I can put our order in the following day to secure the free-shipping discount. If this presents a difficulty for you, please PM me.

 

Please let me know if I missed something.

 

Best!

Yeah just read the PM now and sent the funds. Even though the AUD is weak as fucking shit now compared to the US dollar.

 

Paid via Family and friends with Paypal fee on behalf of myself so I don't get clipped with OP being a scammer or this whole thing fucking up.

 

(Remember what happened to Tran?)

Hi All:

 

We are slightly ahead of schedule. I have received all but one confirmation payment so I went ahead and placed our order with SeeedStudio. I am happy to confirm that we have secured the free-shipping discount and I have received order confirmation e-mail from SeeedStudio.

 

As I mentioned in my earlier post, it's Chinese New Year break over there and their normal work schedule will resume around next Tuesday, Feb. 24. I will post updates on this thread to keep everyone informed of the progress and status.

 

Also, I checked with USPS and found out that they have a flat-rate, padded envelope, priority mail option which comes with tracking and $50 insurance for domestic US shipping. It ends up being about $1 more than the USPS first class mail option that I have originally planned to use. This only applies to the continent US shipping address. I suggest we use this service for those with US shipping addresses. PM me if you have objections.

 

For the non-US location, I will have to wait till we receive the boards for USPS to weight the package and quote me shipping charge.

 

Best!
