Hello everyone- I am new here and would like to get some advice about my tube amp where one of the capacitors for the power tube has starting blowing smoke and I plan to have replaced. I would also like to upgrade the caps to the driver tube as well but would like to do this one at a time. I've included a photo of the driver socket (it's the one on the right side of the close up photo) and its associated caps. I was hoping someone could tell me which cap out of this trio would make the most difference in terms of potential sonic improvement. I've decided on using Miflex caps and would welcome any suggestions on which values for the caps I should be aiming for to try to avoid another blowout. While I've been an hi-fi enthusiast for over 15 years- I've actually never worked on any of my equipment before and am having a friend who works with electronics help me with this project though he is not into audio himself. If I am posting in the wrong place or if more information is needed please do let me know where I should be or what more information is needed. Any help is greatly appreciated.

Moved post to its own thread.Look at the working voltage on the bad cap's label. If you have a voltmeter, measure the voltage the cap is exposed to in the amplifier. If that is at or over the rating shown on the cap, go with a cap that has a higher voltage rating.
