 FS QRO 3KDX mint  
Have a Mint QRO 3KDX amplifier that looks like new.
$1900. Shipping will be expensive and will require removing the transformer. Estimating shipping in the $125 range.
Lots of pics in and out if interested. Amp uses single 4CX1600B. Loafs at Legal limit. This is a beast of an amp. If you have ever owned a QRO you know they are built with heavy duty parts.
Email if want more pics. Thanks
Kevin

 Cooling Fan AdjTime Delay After Shutdown  
Offering the specialized, mechanically foolproof, 115vac relay needed to cool down amplifier tubes for a prescribed time after power off. On shut down,all circuits are off except for the bleed off mechanism which remains activated until the predetermined delay interval is reached. The pneumatic release time is precisely adjustable from 10-180 seconds. At that time, the tubes are cooled, the auxiliary micro switch opens, and the fan stops. Truly a welcomed tube life extender retrofit for any high power amplifier. 3 available. $30 each + Med Flat Rate USPS shipping Carton
