KR Audio VA300

Hello. Recently purchased a used VA300.I have 2 questions for those in the know: 1- It came with the KR Audio 300b tubes, are the 842's an upgrade/recommended?  2-What kind of tool does it take to remove the heat fin structure around the tubes, if replacement is necessary. There is a weird kind of bolt that has a split head so ordinary tools dont work.. Any help would be greatly appreciated, Thanks

If you have a quad of KR 300B's you'd like to sell, let me know.

pianopig that is a monster of an amp I used to own one but it was quite a while ago. Mine had the 842 tubes already installed I would say with that tube it was quite neutral even a touch SS sounding. I never tried it with 300Bs however. And I definitely removed the cages, I blew one tube when I owned the amp, but darned if I can remember how or what tool I used. Try dropping KR Audio a line perhaps. Sorry I couldn't be of more help.
