MA-1 Coupling Cap upgrade

OTL Asylum

OTL, Output Transformerless Amplifier User Group.

Hello all
I'm on a role.

Looking to upgrade my MA-1 coupling caps.
I have V-Cap 0.1uf now. 600V.

Using V-caps online calculator, I should be using 1.0uF.

1) Is there anything wrong with going this high? It's only 450V, is that OK?

2) That little baby yellow 1uF cap. It's coming from the DC offset knob. Could it be changed?. Is it in the signal path?
