My current recommendation is to replace C82 through C86 preemptively on all Model 100s. I've probably seen close to 75% failure rate on one or more of these caps. The rest I would only recommend replacement where indicated; if you see actual leakage or if the machine is known to have lived in a hot and humid climate. The 102 seems far less likely to need recapping, and I don't yet have enough experience with the 200 to form an opinion.
That said, console5 is a reputable supplier and if you have the experience and tools to recap the machine entirely, it probably won't hurt. Most of the dangers from "shotgun" recapping comes from using poor-quality replacements or people damaging the machine because they don't know how to do the replacement properly (improper dwell times, wrong temps, clipping leads and soldering to existing joints), or use poor tools (unregulated irons, poor solder suckers). -Josh On Tue, Aug 18, 2020 at 10:49 PM B 9 <[email protected]> wrote: > I came across a site selling a kit of capacitors for the Model 100/102 > <https://console5.com/store/tandy-radio-shack-trs80-model-100-102-cap-kit.html> > and I was wondering how important people think it is to recap a system > which is working fine.
