Very cool, thanks for looking at it. I'm going to build it and run it without a crowbar circuit for now until I can figure out what circuit to use. I asked for the schematic btw and they said no

Both Craig and Kevin made a good point that I failed to see. If any of the regulators let go it will send unwanted high voltage upstream. Does anyone know if there are some crowbar circuit pcb's out there? There's plenty of circuits I see on the web but not sure what to use.

Anytime...

my pleasure

I see a bunch are delivered already. I'll try my best to post the leftovers this weekend. As far as another group buy goes, I'm open to it. GRLV boards are always popular and I'll add + only (positive rail) split GRLV boards since I could use a few for projects. I thought I saw a while back that Kerry posted a smt GRHV with LV. There's also the TH Buffer 2.0 boards as well so if anyone can think of anything else they need just post it in here

No sweat man... sorry for the wait Sent from my iPhone using Tapatalk

could this be given the GRLV treatment?

Here's some scans of the part list and top and bottom of the board.

Everyone but Nebb, Jgazal, and Samsie are all packed up with shipping printed. USPS will pick them up today at the house, fingers crossed. I'll go through the leftover boards this weekend and post what's left.

everyone's weighed

Everyone's all packed. I'll weigh Friday night and send out address requests as I weigh

Almost everyone is packed. Three or four more to go. Should finish them tomorrow. I’ll weigh them as well and should start requesting addresses in a few days Sent from my iPhone using Tapatalk

Kevin, can I use the Diamond output buffer ver. 2.0 ?

Packing has begun Sent from my iPhone using Tapatalk

That's looking good Jose! I was able to find Diotec BC546CTA https://www.tme.eu/en/details/bc546c-dio/npn-tht-transistors/diotec-semiconductor/bc546c/ And Diotec BC556CTA https://www.tme.eu/en/details/bc556c-dio/pnp-tht-transistors/diotec-semiconductor/bc556c/ They have them in stock for a decent price and sell to individuals like us. I ordered yesterday and got a DHL tracking number early this morning. It says I'll have them tomorrow. They charged like $9.00 for overnight from Poland to the US!

ok, it looks like I can get 546C from On Semi and 556C from Diotec. Did you use same brand?

I have enough B grade but thought it might not be high enough. So it looks like I'll be ok if I have to use that

Is there any problems with using BC546C form On Semi and BC556C from Diotec? I can't find BC556C from ON Semi

7x7x4 boxes ordered, I'll start packaging and weighing this weekend I believe there's a set left but I have to check. Subscribe to or watch this thread. As soon as I'm done packaging this weekend I'll post what's left. I'll most likely do another group but for some GRLV boards and the positive side of the split GRLV. So of course I'll add whatever anyone else wants and if there's enough demand I'll order it.

Here’s what they look like Sent from my iPhone using Tapatalk I’ll need to find some small boxes this week and will also start packing everything up

I always weigh at home. I learned me lesson early on. The only country I haven't been able to do is Latvia for whatever reason.

my pleasure... Oddly enough it doesn't bother me. I just wish it didn't take 4 months for TKD to send the pots

Yay.... There here! The pots arrived today. I'll take some pics and start breaking them down in a day or two. I'm still trying to recover from moving my son into his dorm room this past weekend

The pots shipped today from TKD. I was able to get a tracking number. Hopefully they'll show up by next week

got mine.. Thanks for all the work
