BK Precision Model 1420 Oscilloscope Repair

[KE4EST]

Hello all and Happy New Year!!!
I came across this small 1420 and want to turn it into a simple curve/signature tracer.
Yes, before you ask it will be Mr. Carlson inspired.

I already built the circuit from his design and have it in its own enclosure.  I just run the leads to the channel inputs of any two channel scope.
This will be a good scope to do that with full time, instead of having to move wires around all the time and reset up my main scope for other things.

Here is part two.  The little scope is working.  I also show using it with a Mr. Carlson curve/signature tracer example.
