Bazz Posted November 28, 2006 Report Share Posted November 28, 2006 Well... I have heard (and this is 100% unconfirmed) that older MBW cases were tapped at the correct 0.25mm pitch, hence making the swap 1:1. Dunno how much validity there is to that, but that might partially explain some of my luck? This is also my experience with them, my 1665 which I bought from maria a couple of years ago could change tubes no problems but recently ordered a 1680 from them and it stripped the first tube I tried to insert. I only last night got around to retapping the case and tubes now screw straight in Its not a big deal to fix it just took forever for the tap set to arrive..... in the mean time you have to sit there and look at in pieces Quote Link to comment Share on other sites More sharing options...
thewightstuff Posted November 28, 2006 Report Share Posted November 28, 2006 just fyi, its 3.0mm x 0.3mm pitch theres drawings posted up in The Zigmeisters forum i sent showing the pitches etc for various tubes. while i doubt the difference of 0.05 would make much odds, ive had great success with a fine thread pitch size of 0.35mm, just wanted to let you know both to stop the misinformation and incase anyone was bothered about being exact Quote Link to comment Share on other sites More sharing options...
