Hi there, I recently got a SF Deluxe Reverb from 1967 I guess. All the transformers are dated 606-6, pots are from 65 and 66 the panel is what we call Blackline and of course it has the aluminium drip edge. The thing is the grill cloth, faceplate and baffle are in bad condition and I am very tempted in changing all them, specially the baffle that is falling in pieces. But what do you think? Would the amp lose its value because of the change of the grill cloth? What about the faceplate? I found in eBay a guy selling brand new aftermarket SF Blackline FP. Any comment will be appreciated.
