Happy Birthday Nate!

I am so sorry to see this Todd. RIP Karen, and my condolences to you and your family.

Happy Birthday Dan!

Happy Birthday Colin!

Happy Birthday Steve!

Happy Birthday Jeff! Hope all is well and that you are having a great day!

It might, but seems a little high. That would give you ~380V raw DC, which seems like a lot to burn off for a 300Vdc output. I know you need some overhead for the GR PSUs, but that seems a bit excessive, and you would need to make sure you have adequate heatsinking for the pass devices. I'd wait until someone with more experience with the HV supplies weighs in however.

Happy Birthday Adam!

Happy Birthday Mike! Hope you have a great one!

Happy Birthday, and enjoy the DC that rob posted. Umm, bacon...

I did a board like this years ago for 31DQ10 shottkys (or anything in an axial package) that I've used on most of the GRLV PSUs I've built, etc. I attached the gerbers for this board if you want to have some made for yourself. I would prbably do these in 2oz copper instead of 1oz. Here is a screenshot from JLCPCB's gerber viewer on their site: Bridge.zip

Happy Birthday!

Happy Birthday Knuckles, and I'll echo the hope you (and your mom) are feeling better!!

Happy Birthday Ric!

Happy Birthday Ken!!! I hope you have a great one!

Yes, I've been watching that as well and have enjoyed it.

Happy Birthday!!

Regarding your last statement, Trump was the one who initiated the agreement with the Taliban for the US to withdraw by May 2021: https://www.axios.com/2021/08/20/trump-taliban-agreement-doha-biden Art of the deal my ass...

Happy Birthday Bryan!

It looks like the NC pins of the relay on the board are floating. I wonder if tying these to ground would take care of it?

Are you taking the + signal connection after the relay on the protector board? If you are taking it from the channel boards or before the relay, then I would expect a thump. Taken from the point your headphone jack is wired, it shouldn't thump I wouldn't think.

Good to hear on the caps insanity. Did you use the Kemets? I think those are pretty good, at least I haven't heard of anyone having problems with them though I don't know how long they have been in use and don't recall the history of that brand. I see they are owned by Yageo now. Desoldering those shouldn't have been a big deal. You just need a big enough tip and use a good solder sucker such as an Edsyn or an Engineer. I use a 3.2mm chisel tip on my Hakko 936 iron, and turn the temp up >700F for larger connections such as this. The boards these days are pretty good, particularly 2 layer boards, in terms of reworkability without lifting traces.

Happy Birthday JP!

Those would be fine. Some drop down to the 470uf in that cap as well, particularly if you are trying to get this in a 2U chassis. When I built the one I did for a French user, the 680uf were no longer stocked at mouser in the US. Some discussion in the GRHV thread here:

Happy Birthday Marc!
