Signal generator/Alignment question
#6

Hi Mike, good deal on the recap. I do like to keep the old can in place if possibl. Even if thatmeans insalling the filers under the chassis.
One thing to watch for, those IF can slugs might be slightly stuck or tight. Don't put a lot of pressure on them a the start. Maybe just a little working back and forth lightly to break them loose from their resting place.
You also want to have a tool that will fit right into the slot. Don't use a screwdriver, first because it's metal and secondly the blade may be too thin. I made a couple of tuning wands out of both very hard plastic, and one out of hardwood.
IF you brak one of the ferrite slugs, that's bad news. You light have to disassemble the can, then install a new slug. or some have glued them together. Preventing brakage from the get go is best Icon_smile
The "ear method" of peaking will get you very close to the peak. Takes alittle concentration and no distractions. Keep your signal generator signal to the lowest possible, that will help.
Let us know how it goes!
Gary
