I just found out something interesting about the SBD MT196 kit.
I have always thought that my TBs were 48mm, but more and more I have heard that people are saying they are 45mm - including Richard at SBD and the SBD website.
I was certain mine were 48mm. I now need new trumpets for my TBs so I needed to know the size. I phoned up Steve at SBD to ask what size I needed, he said 45mm. I then stated that I could have sworn mine were 48mm. He then added - "oh, the very early kits were 48mm and can achive much more power than the current 196 kit".
Nice one. Sounds like each time we have spoken regarding my "old style" TBs, it was with the though that they were 45mm. Now it looks like I'm not as bad off for not having the 208 kit as I though!
So - you guys with the 196 kits - what size are yours? (mine are at least 5 years old BTW)
