Hi I have commented on your thread. Mine does not have the extra tweeter speakers or the extra tube. U might be alone on that journey! Seems they are almost all either cosmetically and/or electronically different in some little way. I consider Guild the "original boutique amp." Pretty much all of them, all the tube amps. Each one was made by hand and seemingly at least a little unique, somehow, to the next. Sure seems that way. Even the placement/location of the "Guild" chrome badge on the late 60s ones (like my Maverick). Anything goes!
