Hello, I’m trying to determine the values of Illinois Capacitors cap values in a tone control circuit for a guitar amplifier with electrolytic capacitors the caps are marked TIAA 1000uf, RMRM 470uf, RARA 100uf and RLRM 22uf. The temp and V values are apparent. So for my circuit, I would like to know if I’m dealing with 20% tolerance, or something less. Thanks very much.

The TIAA 1000uf, is the 1000uf cap, what is the voltage and temp rating?
The RMRM 470uf, is the 470uf cap. What is the voltage and temp rating?
The RARA 100uf, is the 100uf cap. What is the voltage and temp rating?
The RLRM 22uf, is the 22uf cap. What is the voltage ad temp rating.
Once I have the voltage and temp ratings, I will be able to guide you to replacements.
These are all 20% which is the value of most electrolytic caps
1000 uf 35v 85 deg. C axial
470 uf 25v 105 deg. C radial
100 uf 16v 85 deg. C radial
22 uf 35v 85 deg. C radial
Thanks
