not of the deep end what ever that means just frustrated when I try to tell newbs how to do things and it get ignored, no prob have fun
in case you missed how to do things mean this
recapping the whole chassis is a big waste time and likely to create problems.
Most caps on the set from that era will be fine.
The correct procedure is to check to see if it works as is (keeping an eye on the power supply caps). If that ok and you feel the need you can change the cans, although they have a good chance of being ok. a vintage cap tester would help in that analysis, the thing you got will not.
After the check out IF there are problems you can use a vintage cap tester and with some understanding of how things work you can quickly isolate the area, check the cap, replace and be done without needless work.
and you dont need to learn a lot if a problem surfaces, that's why you come here. Now if you replace every cap in the set and then come here with a problem... well it becomes much more difficult to help you.
