I got the amp section of an old 212 spidervalve, no speakers at the moment, if i get new tubes for it cause it needs em for sure, in the mean time of having no speakers could i just use it in stand by only hooked up with the line out to my computer or is that gonna hurt the output transformer?

^ yea you have to have at least a dummy load or else you will blow the output transformer.

If you have just about any type of speaker lying around that has the same resistance (and can handle the wattage output) you could use that.
