When a preamp is serviced, the original complaint is addressed, however we do not just button it up and let the customer know it is ready. As a matter of course, every function is thoroughly checked and the entire unit is verified to be operating as it was designed to. Small details like returning every screw to its original location and securing them tightly is part of our standard procedure.
The following is a detailed outline of exact procedures:
All required service is performed in accordance with ORIGINAL components, NO cheap substitutes or re-stamps are ever used. Every switch and potentiometer is washed with Caig Deoxit, then rinsed a second time. All inputs, including phono confirmed as operating as designed. Phono section is also verified as having correct RIAA equalisation curve.
Another unit that the customer wanted a full recap on, and it was detailed afterwards.
