Accessories:

Setup Tools

  • MintLP (opens in new window) - for the standard in arc style cartridge alignment protractors and other analog accessories.

  • Turntable Basics (opens in new window) - Purveyors of a reasonably priced cartridge alignment protractor. This is the best of the currently available two point protractors we've found. Order the standard spindle hole size (.282) version for Galibier turntables.

Cartridge Retipping

  • Soundsmith (opens in new window) - Hopefully, you'll need their services later rather than sooner, but we've heard both Peter Ledderman's strain cartridge as well as his incredible rework of a Benz LP, and we give his work our highest recommendation.

Tape Splicing Resources ...

Tape Splicing Blocks:

While we are advocates of using as wide and stiff a belt as your turntable will accommodate, we realize that some who are reading this page have a drive system which is only capable of using an audio cassette width belt or at a maximum, one which can handle 1/4" wide tape.

We understand that the Radio Shack splicing block (for cassette and 3/8" wide tape) has been discontinued. Individual stores may still have some in stock (part #44-224).

To splice wider tapes, up to and including 1/2" VCR tape, the link to the following sites:

For an interesting story on the use of the EditAll by one of the masters - Harold Lawrence (of Mercury Living Presence fame) - link to a segment of his biography in the Journal of Recorded Music (opens in new window).

Belt Materials:

There re two options:

  • VCR tape - face the shiny side toward the platter - YES ... the shiny side !!

  • Mylar tape - functionally equivalent to VCR tape, but better performing - if you use the holographice variety which is thicker than VCR tape (and thus stiffer).

    Note that the holographic variety is a bit stiffer as well as being slightly wider than 1/2". This presents some problems for splicers like the TAC. The Marker-Tek splicer will work with this wide, stiff tape by using it like a manual splicing block - substituting a single-edged razor for the built in cutter.

Arm and Cartridge Setup

Note: There is a wealth of useful setup information in the links below.

We remind you that our setup manuals and hints live on their respective product (turntable and tonearm) pages.

  • A spreadsheet to calculate the cartridge loading (opens in new window) with moving coil step-up transformers.

  • Cartridge loading theory (opens in new window) and how to do it (opens in new window) by John Chapman of Bent Audio. We need to ask John where his links to these two great pages went.

  • More on Cartridge loading theory (opens in new window) by Jim Hagerman of Hagerman Technology.

  • A spreadsheet to calculate the resonant frequency (opens in new window) of an arm and cartridge combination.

    Note - these numbers should serve only as a guideline. We've seen combinations which should not work according to the numbers which do, as well as the reverse situation (those which should work and which don't). Ultimately, your experimentation, a test record such as the Hi Fi & News Report Test Record) along with your ears (and if you'r lucky, a set of tonearm counterbalance weights with different masses), should be the final arbiter.

    If your browser doesn't display the sheet, return to this page and "right-click" on the above link. Select "Save Target As..." or it's equivalent.

    Note that Column E is a protected column. Protection has been turned on for the entire spreadsheet to prevent accidental erasure of the equation in column E. To add more rows using cut and paste, first turn protection off.

    For this sample spreadsheet, a Moerch arm was used with one row for each of the 4 arm tube masses offered (from 3.8 to 13.1 gms). Most of the fixed mass arms in current production have an effective mass in the range of 10 grams.

    The object is to place the arm cartridge resonant frequency in the 10-12 Hz range. Realize that cartridges, like any other manufactured device have sample to sample variance. The published compliance figures should be used as a point of departure. Use a record like the Hi Fi News and Record Review setup disk to empirically measure the resonance. If your resonant frequency ends up being too high, this is an opportunity to increase the mass of the system by adding the damping compound of choice under the headshell.

    The equation applied is:
    Resonant Frequency = 1 / [ 2 * pi * sqrt(M * C) ]

    where:

    M = the sum of the effective mass of the tonearm and the weight of the cartridge
    C = the compliance of the cartridge.
  • An analysis of linear tracking tonearm geometry (opens in new window) and setup.
