  1. 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
