I'm going to start putting some stuff up on the somewhat new MBP Facebook page. So, please feel free to check in there from time to time. You may find things on there that are not here on the forum.

Also, I'd like to put up pics of some of the contest winners. If any winners have an objection, please let me know. I say this because you own the copyright to your own photos, so I don't want to ASSUME it is okay for me to use them. Actually, maybe it would just be easier to have past winners affirm in this thread whether or not they want their photo posted. Do not feel obliged in any way. I'm just searching for cool content for the page.

GermanCdn pretty much covered it, except the bias point is fine anywhere between 10-12v on Q2. Verify you have 18v out of the charge pump (the build doc already tells you how to measure the voltage for the Test Point, and all you need to do is measure it at the 18v output pad). A remote possibility is fake JFET transistors...it could be the case depending on where you got them. But, that would not be my first guess.

Have you already wired this up? If so, lets see some pics of your wiring, etc.

It's possible it will misbehave if your current draw, i.e.what you are supplying, is too high. The MAX1044 taps out at about 20mA and the LT1054 at about 40-50mA, I think.

What kind of voltage readings are you getting, and are you taking them with no load (IOW not connected to anything)?

Sounds mis-biased. Double check your values for R4, R3 and R8. Have you verified you are getting 18v out of the charge pump? Have you tried messing with the trimpot as described in the build doc?

Great tunes. The Harbor song is just so moody...I really love it.

Global Annoucements / Fall Sale Wrap-Up
October 21, 2013, 03:55:59 PM
Thanks to everyone for making the Fall Sale a big success! My fingers are worn from packing plastic bags, and it's a great thing. You can expect to see more sales in the future...maybe as a quarterly thing. And, there will be something at least for Dec, as I do every year.

Anyway, the success of the sale will translate directly into more projects/PCBs getting made and sooner. I expect to finalize the next batch this week, making the next release in the first half of Nov.

I have it right by my desk, already disassembled. I will look at it tomorrow morning and see about completing the trace.

I have this delay and it is a good sounding one. I've got some of it traced out but never finished it. I can take a look at the modulation and see if I can fill in the blanks. It's pretty straight-forward.

Thanks for the heads up. I'll see about getting that gif uploaded.

You guys are nuts....(and I love you for it)!

You should build the Upper Decker and then tell me if I should finally build it! Plus, the name....my favorite. (I have low standards).

Sorry about the Mudbunnies and Aquaboys. When I placed the re-order two weeks ago, I actually had quite a few in stock, so I thought they would last a bit longer. But, I had a run on both so the numbers were down when the sale started.

I will be doing a re-stock on both very soon. There won't be much of a wait until the next batch of stuff is released.

UPS-MI skips Customs? That is certainly a good thing. I suspect that's were 99% of problems arise with int'l orders.
