Looking at the legs straight on with the flat side down, they're B C E, which is different from your MPSA18. You're going to have to bend the legs somehow, or get a different transistor. yes, for the mpsa18 just bend the "lone" leg (originally on the curved side--the collector) in between the two o...

You're only using 2 pins on the power switch, right? The neutral side of the transformer is just unbroken wire back to the N on the IEC? Yes, is that kosher? I can't get my head around the switching jack either. I've called a couple electronics stores and, while they do say that they think they hav...

It's ALIVE!!! way to go, AE! Fun, isn't it? Careful with this stuff, you'll never get any recording done. Put the lamp in parallel with the transformer primary. That way, they both see the full 120V. Alternatively, use an LED and a resistor, hanging off the 48V or 44V supplies. Hey Scum (I feel str...

So, both the 44V and 48V are wired to the "+out" terminal, the "out" can go to the IEC ground until the chassis comes into play, what about board ground, should I tie that into the IEC's ground for now too? yep! Lastly, the point where the 44V should come in on the board. It looks to me like it's t...

Okay, I still don't have this thing ready to hook up to mains yet. I'm a little scared. I just wanted to clear a few things up first. So I've got one leg of the IEC (L) going thru the fuse, then off to #6 on the dpdt switch. Then I've got #5 on the switch returning to #4 on the power transformer. B...

Thanks for the kind words, BH! I had to go see what you were referring to re. the toggles, but indeed, the (shielded) input and output pairs were NOT soldered in when I took the "toggles" snapshot. In this case, the mic signal source pairs would connect to the uppermost pair of pins, while the outp...

Beautiful work, Brian! O/T, but can you explain what is going on with your toggle switch setup there? from the pic it looks like the signal would only pass if you had phantom switched to "on". I've never seen a phase switching "circuit" like that--i've always done it all on one dpdt with signal comi...

thanks for the explanation. it mostly makes sense. however, i guess i need to read a bit about why the bridging resistor (R6) is necessary. i don't understand why its necessary to connect the pos and neg paths. i see this arrangement often, though. a "U" pad, is it?

Have a look at SW 3 here: http://www.jensen-transformers.com/as/as016.pdf It's a switchable pad, using a DPDT. That's a handy resource. Thanks for posting that. However, I'm having trouble understanding what R6 is doing in that pad. As I see from the schematic, the switch in the up pos bypasses R7 ...
