Running 4 8" speakers- will I have a problem powering those, instead of the original 15" speaker installed?

Buy the book linked below and then buy a few others if you want to learn how to build an amp from square one without any prior knowledge whatsoever about tube amps. It is not reasonable to expect the members of this forum to provide you with the answers to every question you encounter about building an amp from scratch one painfully irritating post at a time. The questions you have asked have repeatedly indicated that you have no business attempting to build a tube amp from scratch without first gaining much more knowledge about the basics of tube amps. The reason that the Forum has a policy of not providing certain technical information is that it is dangerous to work on tube amps if you have no idea what you are doing. In the interest of preventing you from experiencing fatal electrocution, please respect the Forum and go do some research on your own.
