[time-nuts] huntron tracker advice & troubleshooting without schematic advise

[Patrick]

Hi Everyone

I have consistently had success repairing laboratory instruments(my
small business) when I have a schematic and I have consistently failed
without one, lots of opportunities are slipping threw my fingers.

I want to invest in tools that will help me troubleshoot without a
schematic. I was thinking about getting a Huntron tracker. Has anyone
had any experience with one? Could you feedback?

Are there other tools that have helped you fix circuit boards without a
schematic?

Thanks in advance-Patrick
