We are trying to have our tach repaired locally. We have it in our vintage radio repair shop that has determined that the meter is good but the module is bad. The module is potted in epoxy and if the tech could find info that stated the component values he could repair it. This is a long shot but does anyone have any information on these that could be what my tech needs? I know that there are places in the USA that repair them but shipping will get to be as much as the repair.
