I have two other threads going on my SF Pro Reverbs but I need help with this one too. One of my Oxford speakers is blown, no output what so ever. Would I massively kill the collector's value of the amp (its all orignal) if I had the speaker reconed. Or am I better off replacing both Oxfords with another set of Oxfords from another identical Pro (Of which I own another SF Pro that has been modded back to blackface specs and the master volume removed. I would assume that the original/collector value of the modded amp is likely shot to hell, but I have the original Oxfords from that amp). I know these amps are not big dollar collectors amps yet but I do notice the price going up on them significantly over the last few years. Thanks in advance for the advice.
