can anyone recommend a person in LA area to pay to install a tricky Koetsu cartridge

Hi,

Assuming social distancing and stay at home order not violated, can anyone recommend a person in Los Angeles area that can be hired to install a Koetsu Rosewood Signature Platinum cartridge which I understand is a bit harder than most cartridges to install. I have a person or two but they are not currently available.

@amg56, that’s exactly what I did, many times watching Brooks install, align, measure, adjust, then run-in the cartridge for hours on the customer's table/arm,. Then retest and realign the cartridge (all the alignment parameters change as the suspension relaxes). I’ve never seen any other retailer expend as much time and effort as did Brooks, nor with as much care and expertise, and Brian Berdan does the same. All that work is included in the sale price of the cartridge.

Whoever does the setup needs to see the diagram of the interior of the Omega arm, which is pictured on the card supplied for locating the hole for mounting. The bearing is offset from the center of the mounting hole, and affects the arm's effective length/pivot-to-stylus distance. Unless the Mint protractor is made with that information, it will not be capable of providing accurate alignment.

Give Brian Berdan at Audio Elements in Pasadena a call. He was trained in the art and science of turntable/arm/cartridge set-up by his pa, the legendary Brooks Berdan, and is now himself an expert.

Do you still have the cartridge alignment protractor supplied with the Helius Omega? It’s design incorporates a unique offset bearing design which renders a standard protractor unsuitable for the arm. If not, see if you can acquire one from the U.S.A. Helius distributor, Dan Meinwald at Sound Advice in Long Beach.

Great table, great arm!
