March 18, 20206 yr mwl168, I had a look at the bom for the gr78xx and tried to build a mouser project from it. However mouser says the kst42mtf is obsolete and out of stock. Also C3 C7 in the bom is the same as c1 and c2 but is on a seperate line... the gr79xx also uses the obsolete kst42mtf. the gr79xx also has two entries for the same cap, c1,c4 and the line c7. Ok looks like farnell still has some stock remaining.... Edited March 18, 20206 yr by jamesmking

C1, C2 and C3 are different values. A quick look seems CMPTA42 could be a pin/package compatible part for KST42. Same goes for the PNP part. Kerry and others should be able to confirm. Table updated.

March 20, 20206 yr Author We have a few new comers to HC (<= 10 posts) that participated in this GB and have not responded to my inquiries, including direct PM, for confirmation. We need final board counts to get accurate quotes from the fab house for this GB to proceed. The GB participants listed below please respond on this thread with your confirmation or desire to drop out by end of day this coming Sunday, March 22. If we do not receive your response , I will assume you are no longer interested and will remove you from the GB. Thanks! stickyjon23 grendel23 zumac99 Marc Edwards Edited March 20, 20206 yr by mwl168

Do you want the GRHVxxx partially assembled or bare boards? I assume you know the PSU Main board is designed specifically to work with the GRHVxxx boards? Each main board takes 2 GRHVxxx boards to supply a set of +/- HV rails. Edited March 21, 20206 yr by mwl168

I'd take the bare boards, then 6x GRHVxxx3x GRLV79xx3x GRLV78xx3x Main Board3x miniT2 Thanks!
