In my effort to procrastinate doing the things that will improve my life, I’ve been working on improving Shoshanah’s. Specifically, her car. She despises doing anything to maintain her car with a kind of weird passion, so it falls to me. For example, she’d been bugging me to replace the wiper blades on it so her old ones joined a few dozen others in the trashcan outside the auto parts store. Plus, I had found replacement gas lifts for her PT Cruiser ($55 for the pair, shipped); the hatch started drifting down and whanging us on the head from time to time. So I added my sweat to the blood and tears this had cost us (however did I live without this Makita cordless impact driver?! I’ve needed it so many times now) and now the hatch drifts gracefully up with a little nudge, and stays there, like it did when we got it. Sweet.
Now here’s the tough one. Her amplifier. The power amp under the driver’s seat has caught a bit of abuse in seven years and the right channels for both pairs of speakers were having problems. Seems the posts from the RCA connectors sheared off inside the receptacles. I managed to fish one out with a pair of pliers but the other one is way in there.
So being me, I took the thing apart. I was hoping to poke the post out from behind but the connector is buried. To slide the mainboard out turned out to be incredibly involved as this Arc Audio Class D amp consists of maybe 30 amplifier IC’s pasted to long heatsink rails with thermal grease and as many black metal retaining clips. So I let my son remove the clips and I loosened the IC’s from their greasy seal and eventually, after finding a few more screws that were required (and removing a few screws that really didn’t need removing), I slid the mainboard out. A bittersweet victory because I know that now I’m going to have to run to Fry’s to get more thermal grease — the little tube I have ain’t gonna cut it — and grease and clip and screw it all back together. Not to mention rebuilding the RCA connectors without losing much wire — there’s a minimum of play to work with and it might end up being a splice job — and I’ll have to replace a fuse I think because (ahem) the hot brushed the case when I was deinstalling it.
And it turns out that’s not going to be enough. I figured I needed to take a break before desoldering the six points holding the connector block in place. So I sat and had a think, and I think that my best bet is to solder something to the errant post and yank it out when the solder dries. It might melt the connector interior plastic a bit, which is why I had initially dismissed the idea, but I keep getting into riskier territory with this $350 amp and this is starting to sound safer.
The irritating thing is that I could have taken that approach without even cracking the case.
Just before my dad died we were talking to him about family histories. He pulled out a newspaper clipping about the death of Al Jennings, the “last train robber.” He told us of his presidential pardon, and related an anecdote in which wwhen he was released from prison he went to a museum displaying artifacts from his life and demanded them back. After a suit in court, he won, recovered his stuff and headed to Hollywood.
