JoseA Posted March 17, 2020 Report Posted March 17, 2020 I would like partially assembled boards for one set Thank you
gepardcv Posted March 18, 2020 Report Posted March 18, 2020 Please increase my order of both GRLV78 and GRLV79 to 5. Also please add 2 bare GRHVs because they're cheap and why not.
Energy Posted March 18, 2020 Report Posted March 18, 2020 I would like one bare set please. Thank you!
MLA Posted March 18, 2020 Report Posted March 18, 2020 Please increase my grlv78/79 to 6 each instead of 3 each. Thanks!!!

mwl168 Posted March 18, 2020 Author Report Posted March 18, 2020 GR78 and GR79 BOM added to first post.
jamesmking Posted March 18, 2020 Report Posted March 18, 2020 (edited) 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 However mouser says the kst42mtf is obsolete and out of stock.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, 2020 by jamesmking
MattN Posted March 18, 2020 Report Posted March 18, 2020 Just to confirm that I would like what is listed against my name in the table. Thanks!

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.

Energy Posted March 18, 2020 Report Posted March 18, 2020 Apologies for not being accurate. 😅 I'd like the following: (enough for one Mini T2) 2x GRHVxxx (bare) 1x GRLV79xx 1x GRLV78xx 1x Main Board 1x miniT2

I think I've used MMBTA42/92 in the past successfully, though your suggestion Michael looks like it should work as well.
judo Posted March 20, 2020 Report Posted March 20, 2020 Kerry, the GRLV78/79xx can be usable in your dynalo mini ?
mwl168 Posted March 20, 2020 Author Report Posted March 20, 2020 (edited) 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, 2020 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, 2020 by mwl168

It's good for newbie to have the advice. I'd take the bare boards, then 6x GRHVxxx3x GRLV79xx3x GRLV78xx3x Main Board3x miniT2 Thanks!
