"So, I first tried out the .022uf Jupiter Bumblebee and replaced the current 600volt vintage NOS Sprague Bumblebee that was currently in it. 

I was rather shocked to hear no difference between the vintage and yours. I’ve only been playing it for two days now and waiting to see if it changes any, as new caps usually will do. Am really impressed with it so far. Just an hour ago I replaced the Russian K40Y-9 .015uf with yours and expected to hear a muddy cap because that little Russian PIO has been a mainstay cap for at least ten years now. Yours is as clear and great, even better than the Russian. I am very hard to impress too. A total purist."
