    It's not a fun task.

    All going well except around the big box caps:

    I need to pull them out but they aren't coming. They didn't desolder cleanly and the glue isn't helping my efforts.
    Anybody who has been here have some wisdom?

    Thanks.

    If they are clearly desoldered. Bend the caps over at a 90° angle with force. the glue will release.

    What method are you using to desolder?

    I use my Hakko 888 and a cheap desoldering pump, it works good for the most part.

    I got sidetracked, back to the garage.

    Have you tried flowing new solder and retry your solder sucker?

    Nope, I didn't know that was a thing.

    I had to walk away before I broke something, fresh eyes tomorrow.

    The afternoon was spent cleaning and relamping an Optonica SM-3205 integrated to soothe my fix-it itch.

    Try using some solder flux. It will do the same thing as fresh solder, gives wetting that spreads the heat quickly and evenly. And if your de-soldering tool isn't hacking it try using some soldering wick along with the flux. Sometimes that's the only way to get large solder points removed cleanly, along with a large chisel tip on the iron.

    Two out, two to go.
    Love, lots of love and patience to simultaneously work the glue and solder joints. Tomorrow we press on.

    Sold the Optonica today for a decent return on my investment. I got a Heathkit AR-1214 in the same pile, a little slice of Americana that I might keep around for a while.

    Thanks for being there.

    When you only need a 32 cent cap and it'll cost $5 to get it to you.

    All done except...
