OPERATIONAL NOTES

HANDLING - 

The JBL D-130 speaker features an extremely tight voice-coil gap.  It also has a very 

large Alnico V magnet.  Should the amplifier be dropped, the deceleration forces of such a heavy 

magnet could cause it to become off-centered.  Even the slightest amount could create voice-coil 

rub.  Use care when handling this precision instrument. 

POWER  ON   

-  Switch  the  bottom  chassis  and  top  chassis  to  the  “ON”  position  and  allow  the 

“IDLE” switch (bottom chassis) to remain in the “IDLE” position (stand-by mode) for about two min-

utes to give the tubes time to warm-up.  When ready to play, switch the “IDLE” switch to the “ON” 

position.  Do not switch the unit on, off, on in rapid succession.

TUBE  LIFE 

- As with all tubes, their performance degrades with age.  Excessive increase in noise 

(hiss or rattle) can indicate the need to replace a tube.

BULB  REPLACEMENT

  -  As  with  all  bulbs,  your  dial  lights  will  eventually  burn-out.    In  order  to 

change bulbs, the upper chassis will need to be removed from the cabinet.  There are two mount-

ing screws on each end of the chassis (4 total).  Be sure to disconnect the A/C connector from the 

wall outlet and all wires from the chassis.  Give support to the chassis so that it doesn't fall as it 

becomes loose from the cabinet.  Once the chassis has been removed, locate the two bulbs on the 

Top Panel.  To remove the bulbs, gently press down on the bulb and turn counter-clockwise.  The 

bulb will loosen and can now be pulled out.  Reverse the process to install new bulbs and reinstall 

the chassis.  

CLEANING 

- The Illuminated Dial (top panel) may be cleaned with a non-abrasive cleaner such 

as  “Windex,  non-streaking”  applied  with  a  soft  clean  cloth.    CAUTION:  The  use  of  abrasives 

will scratch the clear plastic surface of the dial, which will illuminate the scratch when the power 

is switched on.  Never spray the panel directly, as the cleaner may adversely affect the controls, 

and can contaminate the circuit if it penetrates the chassis.  Protection of the vinyl can be afforded 

through a light application of “ARMORALL.”  Hardwood cabinets will benefit from an occasional 

cleaning with a fine furniture (or guitar) wax or polish such as “Howard’s Orange Oil.”  Avoid 

using cleaners that contain alcohol.

apparent,  The  Standel  Company  can  supply  SUPER  LOW  NOISE  TUBES  and  AUTHENTIC
