Brian, welcome.
Yes you need to replace electrolytic caps, along with ALL other caps including the backelite blocks, as they are also paper caps, EXCEPT the mica molded caps.
The tubular are regular paper caps, not electrolytics.
They are non-polarized and when replaced, there's no end to be connected to GND etc.
Typically tubular all have Voltage ratings printed on them along with capacitance.
The backelite ones are all 630V rated but it is not really needed so you could get the rating according to the place in the sch, or if in doubt, 500VDC rating is vood across the board except for the line filter caps (those connected to the AC line) which have to be X or Y safety caps) and sometimes the single cap connected across the primary of the output audio transformer which sometimes is rated 1000V which is not necessary and most times 500V will do fine.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
