The schematic of OTL pin 3 of 6AS7 connect to 2 units resistors 6.8K ohms to ground with 220uF and 0.1uF capacitors.

If I not wrong, it is high pass filter. Can I replace 220uF with 82uF capacitors?

So RC high pass filter result is 0.212Hz (220uF 3.4K) and 0.57Hz (82uF 3.4K) respectively.


Can I replace 82uF or even 164uF (use 2 of them) which I have better quality than 220uF.
