desoldering

Some of you have seen my post about fixing the DC Offset on the M7 receiver I have. I'm still going about gathering my equipment and learning about soldering better than I currently can as well as using junk to practice on, but I have a question about de-soldering on the M7. Being new to...

Note: I’ve read through the thread “What test equipment should I use? What are you using?” before posting this. My goal here is not to duplicate it, but to share a clean, structured checklist aimed at beginners starting from scratch. I hope it can serve as a practical entry point, and I’d love...

Hi, I am recapping a Luxman R-1030 for a friend and have two small questions. There are elco's in a type of housing I have not seen in my previous recap projects: little blue elco's. Are they also to be replaced? (see picture) Second question: The schematics I have from this amp (from...

I need help with desoldering: I have been progressing in my repair techniques for gear, and have learned to solder with good success. I have also been successful replacing some caps, and other through hole components. I have a spring loaded desoldering pump, and one day, I might treat myself...

I could use a few tips from those with more experience than me. I'm in the process of going through a Dynaco SCA80Q that I built back in the middle-to-late 1970s at the age of 15 or so, with the help of some excellent supplies, tips, and support from Dan Joffe at updatemydynaco.com. Have...

I have just took the capacitors out of this power supply, and I'm a bit worried about those brown-ish spots that formed around the connections, do these look like I burned the board? and if so, anyway to "fix" it? I have read that burning things is unlikely if you're careful because not many...

Hi folks - I'm preparing to do my first recap and I would appreciate any tips on desoldering the old caps from the pcb boards - I'll be working on an old magnavox solid state receiver. questions: When removing the caps, will I just heat each lead and wiggle it out of the pcb hole? Does it take...

I am re-capping this beaut but the old solder refuses to budge. I am using a Hakko FX-888D at 875 degrees with a nice broad tip. It doesn't touch this solder. I have also tried adding some Kester rosin core solder, but once it touches the old stuff it freezes up and becomes unmeltable itself...

For those of you who haven't seen a powered solder sucker or desoldering pump in action, here is a short video of the Hakko FR-330 in action: (And yes, that is WAMU's Hot Jazz Saturday Night playing in the background)
