Hi, I'm currently using a friends Model T that I'm most likley going to buy,hoping to get some info from someone out there...The serial# is 034367...any clue as to the year?Also it says "Model T" on the back and has what seems to be a Plexi logo with "Sunn" silk screened on the back side,it has no trademark insignia.One other thing,the master vol works more like a gain stage...it does not control the overall vol more like you dial in a little "sack" with it and the inputs(all five) work exactly the same.They allow the mixing of channels but I was just wondering if these were common mods to these amps?Either way the amp kicks my head in every time I fire it up.Hope someone can enlighten me a bit about it...Thanks
Pete
