Looking for Compass Yukon Nugget and Fisher Metalertmodel 70 User manual/schematics

[rickb]

I am planning on using the compass for a DD IB platform for experiments as the control box has more room. This compass has only 1 control and speaker. The Fisher works but has very little room. Would like to learn a bit more about the theory of operation and usage of both before repurposing either one of them. If you have >any< knowledge about them, I would like to hear about it.

Looking for Compass Yukon Nugget 84 IB and Fisher Metalertmodel 70 User manual/schematics

Correction and addition to the above post.

I am planning on using the compass (model 84 IB) for a DD IB platform for experiments, as the control box has more room. The Fisher works but has very little room. Would like to learn a bit more about the theory of operation and usage of both before repurposing either one of them. If you have >any< knowledge about them, I would like to hear about it.

You might want to check here first for theory of operation, someone over there may remember using this model?

The 84b schematic was previously posted. Here it is again

Thanks. That looks like what I see on the circuit board.
