Hey Folks,
I just bought a 300-5 PA system. The power comes on OK but the Blue light doesn't come on. Replace bulb or switch?

Also the system has 2 speaker cabs with 2 15" speakers and a horn. The cabs are 2K +1HP, anyone have information on these? They are very heavy!!

Thanks,
Ray

Hello!
In the 300 head as with all the metal face amps the bulbs are in the switch behind the blue lens.
If you pm me will pm you to get your email adress so I can send you pictures and instructions on how to safely change out the mini bulb without breaking the switch as some times takes place.

Those are one of the correct optional speaker cabinets you could get with that 300 pa head.
They are loaded with Kustom / Eminrnce made 15" drivers and a Altec Lansing horn driver..

If from this site's main page you go to the Literature section and then hit the more T&C tab you will find the Kustom PA brochure that has pictures and info on this gear.

Thank you very much! The people at Kustom were no help.

my email is rdjennings335@yahoo.com

The system was sitting in a barn for 10 years with the covers on. It looks almost showroom condition, the goldish sparkle is perfect, the grill cloth
is excellent the horns are great. The only issues are the POTS are very scratchy, the blue lights for the on/off and Polarity switches do not work and #1 channel doesn't work. All other channels are good. It will be great to see the literature so I know what does what. The speakers are 2X15 Altecs and 2X15 Stock Kustom, they sound great.

Thank you again and any information is appreciated.

i would imagine the polarity switches no longer working was intentional. they don't call it the "death cap" just to sound heavy metal

The bulbs are replaceable, they are GE 335 bulbs.
The best way to replace them without doing damage to the 40 year old switch is to first remove the amp from the cabinet.

Then remove the metal lid from the amps top.

After that use a big flat blade screwdriver to push out the switch lens cover towards the face of the amp.

Next get some automotive vacuum hose that fits a new bulb tight and then use that as a extension handle to extract the bad old bulb and install a new one .

A wipe of grease or Vaseline on the new bulbs treads will stop it from rusting in the socket as they sometimes do.

Then support the rear of the switch when you push the blue lens cover back on.

Hi Ed and welcome!

It took years of searching , but a found a replacement switch that will work in these metal face amps.

They are as close as you can come to the original one and are more heavy duty, the down side is the cost of them as they are sold in seperation sections , as in the switch , the lamp and the blue lens.

I sell them complete for 70 bucks which includes shipping within the US.

Pm me if your interested.

Im looking at a K250 now that is missing the blue square/lense part. The guy says that the switch works... just missing the square. Do you know where I can find one (or two) of these?

Finding just the lens cap for sale by itself without the whole switch, or the whole switch in a junk amp might be fruitless!
