The Multi Amp aka Dynalo Mk2
This one has been brewing for a while now but since I wanted to build a nice balanced amp it moved up in line. Basic setup is the same as the old Dynalo but now with Super Symmetry input, higher rail voltages and naturally a bit more power. Input stage changed to THAT340 which is a quad bipolar transistor array with matched NPN and PNP pairs. It is cheap and easy to source so no jfet drama. The other transistors are new as well and the pinout is different to reflect that.
Here is a lo
I haven't started building my board yet, but the pitch on the regulator appears to be about the same as tsop40 and some qfp packages I'm used to soldering/desoldering. I'd recommend positioning the regulator on the board and holding it in place with tweezers. Flood the area with no clean flux, then with a fine chisel tip try to tack down one corner of the regulator, then move to the opposite corner, adjust the positioning if necessary then tack that corner down. Reflux the chip and load your tip
