Hi: I just placed an order to have 10 sets of KGST boards made. A few of them are already spoken for but I should have 5 sets available to those interested. Here are some details: 1. The amp board is KGST6S4CASCODE (120mm x 135mm), the PSU is KGBHULTRAMINPSV4 (105mm x 134mm). 2. The boards are all 2mm thickness, 2oz copper, green silkscreen with white lettering. I wanted the thicker board that can better sustain the mounting and dismounting of the tubes. 3. I am using a PCB fab house in Taiwan which was recommended to me but I have no prior experience with them. 4. JimL has traced the cascode CCS part of the KGST6S4CASCODE board (see KGST thread), I traced the rest of the board by comparing it to the KGSTMINV03 board. However, to my knowledge, no one has built the KGST6S4CASCODE board yet so it should be considered un-proven. 5. The cost for each board set ( 2 amp PCB and 1 PSU PCB) is $50 USD plus applicable PayPal fee and shipping cost from me to you. 6. I may potentially have one set with 1.6mm thick, 2oz copper KGSSHVPSMINIFINALSTN9360 PSU board available but cannot promise. Please respond to this thread if you are interested. If there are more interests than can be accommodated, inclusion will be based on a first-come-first-serve basis (FCFS). I will PM those respond their interest with my PayPal account and further logistic information. please let me know if you have questions. Thanks!
