Anyone building the Drip U73b?
I am saving for the Sowter transformers and wondering if anyone will use Edcor?

Impulsstudio said:Yes, I‘m almost done. Used Sowter and thought about Lundahl...no experience with edcor.
But I stuck currently because of some issues with the power supply...as soon as I connect both channels to the power supply it won‘t make it up to 215v (only 200v max), that‘s not the case when I just power one channel.
And the meter needle is far away from zero, no meter light...
so I maybe not a big help.
Sadly Gregory is not answering since Months...but I guess no big news for you.

Michael Tibes said:Does he provide schematics for his pcbs? If so, people here might be able to help...

Impulsstudio said:Yes...all documents are published on dripelectronics.com (Gregory really did. a great job here) and I get better in reading them(schematics) but it takes time.
I’ll leave a short “made it” here when the beast is alive.

Frontpanel is not very accurate, will do another one when I’m done and the varicom is installed.Impulsstudio said:One channel almost calibrated, last two steps still not working...have to leave this project for about 2 weeks alone, but i’ll Update here when I’m back on track.
JMan said:I’m just jumping on to see any updates that come from this.
I purchased the U73b PCB from Drip, along with the Varicom, a couple months ago, but I haven’t started working on it yet. It seems like Gregory’s documentation is pretty thorough, but I have to admit I’m a little worried about starting on one of his projects (I have a couple of different PCBs of his) because his communication is so poor, and there aren’t really community build threads for any of them. I’ve had some luck getting ahold of Marie at Drip, but she passes technical questions along to Greg, and then the comms go dead. Hopefully the folks here are able to work through this project and help the rest of us out![/color]

chrisenglish said:This is why I started this thread! I successfully built the Dla2a and owe a lot to the community thread here to guide me. I designed and fabricated the face plate. So I have some limited skills but it would be really nice to have some input from more skilled diyers.
Michael Tibes said:Drip doesn't publically publish his schematics, I believe you receive them only when you buy from him. This kindof keeps the possibility for help a bit limited...
Michael
Michael Tibes said:I guess I was mislead by the publically available manual which somehow implicates that there was another version of it including the schematics for paying clients. It seems like the schematic on the website is 'the one' - which is basically the original with some notes from Drip?
