i use about 600F for soldering threw hole parts and about 700F for chassis connectors and cables

This is my first full blown amp project, besides the normal cmoy stuff Millet with Nichon Muse KZ, and Silmic II output caps + Tread

hmcelectronics.com thats were my girlfriend bought mine for my bday

make sure your iron is turned up quite high those jacks are a pita to solder

got home today soldered the pot in, and all is well, biased down to 13v

Hey, i just built one of the new group buy boards today and am having an odd problem. I have no volume pot installed, and just booted the thing up to test the bias and make sure all the readings were correct. Odd thing is that im getting the full psu voltage 23.4 at the bias test points on...

i wasnt talking about the actual tip that gets dirty, of course wet sponge.. but the part below the tip the non shiny metal part that the flux builds up on the are bewteen the red lines

Quote: Originally Posted by tangent If you mean the ring of black gunk just above the shiny part of the tip, I don't worry about that. It goes away when you change the tip. well then it serves no problem and it shall be no problem

Hey guys, i just recently got a hakko 936 station for my birthday. Ive been using it alot the past few days and have noticed one thing. In constantly wetting the tip when its not in use the tip has built up alot of burned flux, below the shiny metal part, its not doing anything bad but i was...

im not sure if current sinking the buffers will do you anygood at all. but then again i could be wrong

do me a favor and download this student version of spice and draw your schematic up right http://www.electronics-lab.com/downl...ck.php?fid=513

here are some pics of the completed work
