"Packed not shipped' sounds promising. Anxiously awaiting the next phase, ie "!!!!!GONE and on the way!!!!!". Thanks for finally getting to it.

I'm still waiting as well, but unfortunately, my patience is wearing very thin. If my package doesn't arrive soon I'll take the issue up with Paypal. Enough is enough.

Assuming an OV condition would most likely be caused by a single PSU, logic would suggest that your red version with individual OV modules is the proper option. A single OVP module overseeing the total voltage would have no way of knowing whether PSU1 or PSU2 was the offending supply (without a grou...

I'm actually encouraged knowing that others in US haven't received theirs either, probably suggests he simply hasn't got around to sending those out yet.

Try PMing "E.A.S." (leave out the quotes but put in the dots, his real name is Mike)...... he recently shipped some that went with one of his modules, I ran across mine last night. Perhaps he'll reveal his source to you.

I clean all my PCBs with either alcohol or spray on flux remover. Both work similarly, the alcohol is way cheaper. And yep, it takes several scrubs & rinses in order to get everything off, otherwise you're left with that sticky residue. It's harder to clean the top surface with everything populated,...

180 .37 ohm resistors in series IS gonna be ugly ;-) I guess I'f dig around the component pile for something closer to 60ohm. What I really wanted to hear was... 330 will be fine :-D Take the other approach... an 820R and a 750R in parallel would give you 391R, close enough to 390 for gummint work....

No problem at all. I usually greenline my schematics as I populate boards, but in this instance I decided to simply use the BOM since it was so nicely arranged, and with the values on the PCB it really helps move things along. (I much prefer that to component numbers, which are great for ID purposes...

I just noticed that the BOM includes two R7's.... fortunately I use the BOM to check off things as they are populated and had completed the 10K (which is what R7 is supposed to be, according to the schematic) prior to getting to the 100K, where the other one is shown. I'm surprised no one else has m...

Express delivery and Futurlec? Seems to me the two are mutually exclusive, as they don't typically wind up in the same sentence. I could be wrong, but.................
