Buffer Build #2 smaller than the first

[vanhansen]

Since I like the IC buffer from General Guitar Gadgets so much, mainly because it is simple to build and does its job well, I decided to come up with the smallest perfboard layout I could so it could be house in a smaller enclosure than the first build I did.  What I came up with even surprised me once it was finished.  Check out how it stacks up to a 9V battery.    What a way to start my second year of doing this.

Ohh yeah, I love those tiny-tiny-perfboard-size circuits. But i dislike wiring it up. It usually gets lost in the ratsnest. Then it's damn hard to debug.

That's cool !
My 9v - 18v MAX1044 build is about that size, fitted in a "tiny" Bimbox
enclosure that's 4 cm X 4 cm  !!!

Whew.  Glad the forum is back up.

I have a very narrow Hammond box that this one is going in to.  No switch, no battery.  Just in/out jacks a LED and DC jack.  It will be powered by DC only since it will be on my pedalboard.  

My first build that I'm using now is always on so I have no need to turn it off.  It's also in a plastic enclosure and it picks up a radio station pretty darn clear if it's right after an overdrive pedal or if I have my guitar cable not quite all the way in the guitar jack. This buffer is great at the end of an effects loop chain, which is where I use it.

I figure I'll have 4 wires going to it, In - Out - +9V - Ground.  The wiring should come out pretty clean.

Marty, with an enclosure that small, how do you plug in to it?

Ok, well, since the forum was down again for several days, no fault to Aron, this gave me time to get this one boxed up, a little at a time (no pun intended)   .  It's housed in a Hammond 1590A.  No battery power, just wallwart power since this one will sit on my pedalboard.  One evening to drill the holes, the next to wire it up and test that it works, and this afternoon to replace an LED with broken leads (I hate it when that happens).  There is no switch, it's always on, which is how I've been using my first build anyway.  Works like a charm.  The compact layout I posted a pic of earlier is very quiet.

Thanks again to Aron for getting this back up and running.
