Default Re: Roberts RT7 - problem

You might have cooked them. Sorry if you have. Take them out and test them, Base to Collector, Base to Emitter, Collector to Emitter. The Base should read one way but not the other. There should be no reading Collector to Emitter. If this is not the case, put them in the bin.

There's two resistors, one 51 Ohms and one (on the battery line) considerably more. You should see them on the sheet. Check them, especially the 51 Ohm one. (You have a meter I take it).

Cheers,

Steve P.
