My bench supply went bad now it’s putting out 20 volts instead of 13 .
Do I have to replace all of the transistors in the supply or only the ones that went bad ?

Would it be too much to ask for a bit more than 0 information about the make/model supply, photos...?
There are 5 in parallel. Replace all of those, at least. The 6th is a driver. You may as well replace it as well.
Very carefully check the 0.5 ohm resistors as well.

If you have the driver and at least one other transistor in the supply, you should be able to determine if the rest of the supply has survived.
Actually only 1 of the transistors is bad I removed the bad one and powered the supply up and it’s back at 13 volts .
Is it ok to rub this supply with one missing just for a day or 2 until
I can order all new replacements .
Only asking this since I have some repairs to do
