WORKING CONDITION: Excellent - These modules are in excellent working condition. All I/O is fully functional and the preamps sound fantastic. They were just serviced for this listing by one of the best techs in town where they were tested for noise, level, THD, and PSU ripple. Tubes were tested and one tube was replaced with a period-correct NOS Telefunken EF804 tube. All four are in excellent working condition! 

 
PHYSICAL CONDITION: Very Good - These modules are in excellent physical condition. The faceplate we had custom-made recently here in North Hollywood where the top and bottom rack holes were incorrectly drilled, so we had them re-drill new ones in the correct spots.   Additionally, please note that these modules are not swappable, as the front panel controls are hard-wired to each associated module. Otherwise, everything is in very good physical condition.

Given the weight of these modules, despite 4mm in depth of the faceplate, we are concerned that the long-term weight of the modules on the faceplate might fatigue over time. The modules should have support at the rear (laying some material such as some foam or book horizontally underneath all four should be sufficient) and the rack assembly should be handled with care when moving.

Note that the rear I/O assembly rail is shown in the photos as unscrewed from the modules but it does easily screw back onto the rear of the modules securely.
