I bought a used Tenma 72-720 for cheap off eBay. I got a trace and could dial it in but it was a little fuzzy and had some slight curvature at the edges on a flat line. I don't know if the electrolytics leaked out goo or if it was glue but I decided to replace all the electrolytics to be safe.
Now I'm trying to perform the calibrations listed in the manual and there are instructions to short or open the TP terminal on the V PCB.
I can't find a "TP terminal" on the Vertical Amplifier board or elsewhere in the literature.
Does anybody know where or what that terminal is?
I attached the manual. Pg 18, section 5.
Thanks
