We have seen several customer units where these parts shorted for no apparent reason, creating serious damage.

I am/was considering buying a BAT VK 55se from a local gentleman, however, your comment gives me pause.
"We have seen several customer units where these parts shorted for no apparent reason, creating serious damage".
Are the problems stated showing up in all the BAT amps, or are they limited to a particular model? I just don't want to spend $2500 for a amp that may self destruct.
Thank you.

We are not using them in our units, and the production parts do not have that failure mode.
The reason we changed out the original .22uf oil caps is because we all experienced an almost 100% failure rate, the caps were simply drying out probably due to the heat and poor seal design of the aluminum tube capacitor. I had asked the manufacturer of these caps as to which cap would he would recommend due to the heat and seal issue and he suggested using the copper tube variety which could tolerate the higher heat and had a better seal. I've also tried using their paper tube variety, but the best sound for me is the copper version, the only one I haven't tried is their ceramic tube version. These caps are the manufacture's higher end products and to date (going on 7 years) haven't seen a cap failure, but the best part, together with the better electrolytic caps, and other quality parts the amp is very stable and the sound is simple incredible.
Victor;
Thank you for the clarification.
