Hey, don't laugh if this is some sort of crazy common knowledge. Recently I was in a strange fortune to have a 1 - 2 punch buying a 68 twin reverb and a 69 super reverb for roughly $550 each (super deals). Neither amp is connected. Bought one on ebay the other local. Anyways, I decided it would be interesting to proove their dates. IT was easy enough since the twin had a couple of 67 transformer dates and one 68 and the super had one 69 and two '68 tranny dates. WHich make them the right age amps. (even though the super is missing the drip edge... I think the whole grill was replaced at one point anyways.) My point of this post is to mention it occured to me the 68 faceplate has strange black line vertical dividers and the 69 does not. I have never read anywhere this mentioned. it seemed odd. I then proceeded to find as many 68s as I could on the net to find that all 68s have the black lines, and all the 69s do not. And where there was an amp that CLAIMED to be a 1968 and not have the black lines, a quick rundown of the transformers show them all to have 68 dates (which we all know means its a 69 or later since fender usualy had 6month to a year lag in putting parts in). SO... why does this matter? well, I think its really cool way of prooving if someone is trying to claim an amp is a 68 when its really not, which might happen more than not since '68s have a chance of being blackface ciruits. Here's a pic of my two amps for reference. any thoughts?
