I need a manual or at least some information for a "TS-1100/U Test
Set, Transistor". I've found two by "Googling": one company wanted
$6.00 but its website is down, the other wants $23.00 but I hate to
pay that much when all I want to do is "play" with the test set. In
particular, I'd like to know what battery voltages are required,
where they go (apparently it can use two different sets of batteries),
and perhaps the circuit of a "battery eliminator" for it.
