WORKING CONDITION:  Very Good- Serial #MAN3505290 was allowed to warm up for about 15 minutes; all tubes glow evenly. Signal was fed into it, and it performs and sounds wonderful. No issues to report. 

Poor- Serial number #MAN3305283 -Only the faintest sound coming out for MAN3305283.  All tubes glow evenly; the unit appears stable with no apparent issues other than a very faint signal. No troubleshooting was done beyond testing. It is presumed to need some service beyond our scope. Given its physical condition and value otherwise, it would be worth sending to Manley to get serviced.  

NOTE: The pin configuration for the XLR Input is "Pin 3 Hot". 

PHYSICAL CONDITION: Very Good- Both amps are very clean on all sides and look great with no major blemishes to mention. They look as good in person as they do in the photos. The rubber feet on both amp have become a little "gummy" from age and should be replaced if one is not going to mount these in a rack.
