October 13, 201312 yr comment_603871 My zener power supply is up and running and temporarily cased. I couldn't find a 27V transformer so I've used a 25V one, which results in an output voltage of the power supply at ~20.5v. Is using a 25v transformer a problem? Report
October 13, 201312 yr Author comment_603875 That is right depending on the second stage zeners. If unreg voltage is at least 35 you will be fine Edited October 13, 201312 yr by kevin gilmore Report
October 19, 201312 yr comment_605001 looking good ford. i'm placing orders next week along with a TX from SumR. Report
October 20, 201312 yr comment_605090 Cheers. Do you have a cost on the TX? Edited October 20, 201312 yr by fordgtlover Report
October 20, 201312 yr comment_605092 not yet. i'm contacting Richard on Mon. 27V/50VA i'm guessing will be around $50-60 + shipping. i'll let you know. no 4.7uF Wima from Mouser until mid Dec. may try to parallel 3.3uF and 1uF with the latter mounted perpendicular/flush underneath the pcb.

October 20, 201312 yr comment_605119 You can try the Wima distributor instead. They sell small lots. Report
October 21, 201312 yr comment_605214 thanks Bigir. i have a bunch of 50V 4.7uF Wimas in the parts bin with 5mm pitch. any issues going with a lower VDC rating? since we're looking at decoupling rails of 21V and compensation on the DC servo, 50VDC should be safe? Report
October 22, 201312 yr comment_605393 great. i went ahead and ordered a SumR 2 x 27V/50VA at $54. Report

October 31, 201312 yr comment_607061 I've got some PMs out to try and get a board set (lil knight). Any other leads would be appreciated. Looks like this is going to be a cool build. Report

October 31, 201312 yr comment_607077 I may go that route, but figured I'd try to get on someone else's run to help keep everyone's costs down. Is there a suggested service that has successfully done a run with these files? Thanks for the reply!All board files are available if you want t have boards made Report
