Another newbie question (choosing capacitors)

[dtvmcdonald]

If they look like paper, just buy film (radial) Panasonics in the correct values from
Mouser or Digikey. Its traditional to use 630 volt ones unless a much lower
voltage (like 50, 100, or 200) is specified and the 630 volt one is just too large.

At that age set, you are unlikely to need a cap that is like 0.05 uF. If you do,
replace with the nearest standard value. Get 10% tolerance caps unless a
5% tolerance of better is specified.

If a higher voltage is specified, get that.

The only exception is if it is connected to the power line. Then you need special "safety caps", look that up here at videokarma.

Paper caps are easy! Just do it.

As to how I learned ... I did it at age 11 by building Heathkits and reading. Read
things like 1955 vintage books. Also the repair columns in that vintage trade
magazines: e.g.
