When I worked doing guitar upgrades, I was surprised how lead free solder can affect tone (in a bad way). It made me think *all* the chinese stuff suffers from poor connections, of just crap conductance or something. Thanks for sharing your experience.

I go through micro wire cutters (like Hakko CHP-170) more frequently than I like. I've tried different brands, but they always suffer the same fate: dullness and more aches in hands over long periods of time. Sharp tools are a wonderful thing. But... any advice on how to sharpen them? The problem seems getting a belt or stone in the small area between the blades, and most don't seem user-serviceable to disconnect an arm/blade.

I gave up on the good ones and just started buying the disposable Harbor Freight copy. |

How essential is an oscilloscope? I've seen some projects (AML?) require one for calibration.
Where can one find a cheap oscilloscope?

You could clamp your dremel in the vise, put on a small drum or disc with the appropriate abrasive and try that. Or a set of small flat files. |

Although nothing beats a good powered vacuum de-soldering tool - my Hakko 808 changed my life - the expense can be hard to justify.
I keep one of these in my out-call kit, it works very well:

this one is like $53
Like on 1081 where you set the crossover point of the amplifier (zero crossing bias) you would just need to see the waveform. You can always use computer based test signal generation like from a web site if you don't want to spend $50-$100 on an audio function generator,
Transistor checker would be useful for selecting the parts so they match specs correctly. As you select the set of transistors correctly in a matching affair.
