I have two Mk3s with the VTA driver board and both work very well without any problem. They both have the original quad caps as far as I can make out. As they are getting on a bit in years. I am looking to mod the amps to make them more rugged such as the diode mod to support the tube rectifier and new quad caps with a bit of surge overhead for robustness.
I just want to ask the forum if there are advantages to replacing the quad caps with ones of higher capacitance such as 80/40/30/20 uF or 40/40/20/20 uF. Does higher capacitance adversly affect the VTA driver or power transformers? Is there likely to be a noticable change in the sound of the amps? I am looking at the Authenticaps sold out of Germany only because I live in the UK and they seem to be an economical choice.
Any comment or advice greatly appriciated.
Best regards to all
