What size tube is needed for a gen crown for a TT sub. Tried searching for how to swap for a gen crown couldn't find anything. Could use some help new to modding. This is my new found hobby, very addicting. Thanks.

The tube is PN 24-7030-0 for a 7mm tube- last 0 denotes ss. 24-7030-8 would denote a gold case tube- you rarely see those.

Crown is 24-703-8- gold 7mm.

If I were doing a TT sub, I'd use the ss tube and the gold crown- it's not that big a deal to me.

Keep looking for tutorials, there's bound to be some around- hidden deep in the bowels of the archives!

I remove the rep tube with a rat tail file. if it's glued in, you may need to heat up the case (movt is removed, of course).

You should then tap the hole with the 3.0mm x .35 tap to at least clean out the glue/gunk.

Check the size of the case tube threads you remove- if they're close to the gen/aftermarket 24-7030 tube you can just run the tap thru. If it's too tight, you may need to drill the hole- 2.65mm drill bit- not easy to find. I have broke off a tap in the case once- MBW case- don't think the new MBW cases have such a small hole.

You will likely have to slightly countersink the tube hole in the case as you will notice the gen type tube is constructed differently than the rep tube.

I could REALLY use a WM9 bezel for my latest v2.(teeth are shot)

And I would REALLY appreciate of anyone has or knows someone who has a WM9 bezel for sale.

I will have to resort to gen otherwise and am hoping to get out much cheaper.
