OPTIONAL CARTRIDGE LOADING

Instructions-

For Qualified Personnel only

Optional cartridge loading is a “fine-turning” matter, and many cartridges work quite well without it. ONLY a cartridge’s manufacturer can provide proper recommendations for this process, as every cartridge is different. And ONLY you can say for sure whether or not it produces meaningful sonic improve- ment-for you. For those who wish to change the factory installed loading, we have included a very flexible system which automatically switches loading components when MM or MC is selected.

Your preamplifier has been supplied with 100 ohm resistors and 220 pF capacitors installed in the appropriate sockets. While these values are suitable for most cartridges, you may wish to alter them as described below.

The preamplifier must always be UNPLUGGED from AC before removing its cover. Full AC line voltage is present at numerous locations inside the unit.

Remove the 4 screws under the unit which securethetopcover, and slide it off, to the rear. The diagram below shows how to cut, form and plug-in optional loads. Observe carefully which sock- ets are for MM (capacitors) and for MC (resistors).
