Ikeda 9tt retipping

I think you typoed/misspelled Ikeda, it's this cartridge, correct?

you might write Steve Leung owner of VAS and ask his advice, get price(s) even if you have someone else do the work.

"The cantilever is made of a double layered duralumin pipe in order to reduce its actual weight and any possible warping affecting the sound badly, in addition to gaining stiffness."

My instinct would be to use an advanced stylus on a boron rod rather than stick with two layers of duralumin which in effect is a thick aluminum tube, have a look at info and charts relating to light/hard found here

I recently re-discovered, Shure's MicrowallBe beryllium tube was .0005" thick.

"Duralumin" is an aluminum/copper alloy. Not pure aluminum. Probably a step or two up from pure aluminum in cantilevers.

lewm,

thanks, I was too lazy to look it up because any clever name, if part aluminum, it isn’t high on the hardness chart, mixed with ....well, now that you tell me copper, it isn’t light/stiff either,

they talked about double wall duralumin tube to prevent possible warping, which is partly the benefit of tapered aluminum, correct?

I have seen bent and twisted aluminum cantilevers, I always assume from playing with serious under/over tracking force and anti-skate imbalances, (not warping like damp wood might warp all by itself).

with stiffer boron or sapphire ... i.e. materials that don’t bend, or warp, (they break, or like microwall beryllium tube, simply shatter), serious long term not enough or excessive anti-skate results in permanent sideways deformation of the softer suspension material, resulting in crooked cantilevers, too heavy tracking results in ’low rider’, the suspension has been mis-shaped so the cantilever angle is reduced, the bottom of the body of the cartridge getting closer to the lp surface, and the VTA no longer basically correct when the tonearm is parallel to the LP.

Some are ’low riders’ by design.

When I tried using Wayne’s perimeter ring, I realized, ’low riders need not apply’, the bottom of the cartridge is above the added thickness of the ring’s material on top of the LP when you start track 1.
