Generally, the fuse only blows when the rectifiers fail. In other Pyramid supplies, they use a square, 4 terminal bridge rectifier. They probably use the same thing in your supply.

Let me know if you have any other questions.

Model 36kx. How do I get it to stop blinking and buzzing with nothing hooked to it?


You probably have a switching power supply which requires a load connected to it before it is turned on.

1998 plymouth breeze hazard flasher fuse keeps blowing


check the hazard switch pull the switch and put a volt meter on the connections with wiring connected to switch if it don't respond or just gives you a L.O your switch is bad and shorting out could happen just from being used a lot or something internal broke switch for that shouldn't be all but 50$ or just go to a parts/scrap yard

The fuse blew, can't read what the ampage is


This doesn't compute as there is no fuse external to the unit and it runs off a 12 volt wall wart supply. The supply is 500ma or more. Any INTERNAL fuse would probably be rated at that or slightly higher like 650 ma or even 3/4 amp. If the internal fuse blew it was for a reason... using wrong adapter probably would do it... Other than that take it to a competent repair shop as the fuse will probably blow instantly again. This appears to take 12 to 20 volt 500 ma minimum wall adapter with CENTER positive, unlike many devices. If you put wrong polarity adapter that would probably blow the fuse and MAYBE another component.

Pyramid PS36KX 32 Amp used for cb radio base/amp blew rear fuse i replaced it and somthing inside smoked. took the cover off and there is square things with flat conectors on them. one was cracked in the...


Is the pwr supply the one that blew. if so that is a fullwave bridge rectifier. around 40-45amps that is what makes the AC wall volts from transformer into the 28volts DC to run the power transistors in the rear on the heatsink.

Re: Pyramid PS-36kx power supply buzzer sounded,red light came on


Hi! I saw your question, and maybe this will help. I also have a Texas Star 100w amp, and this same power supply. Even though the nominal draw for your equipment is way below the rated amp flow of the power supply, when you key up, and the output on the amp is at max, you are drawing the limit of your power supply! Try running this setup at a lower linear output. You don't need the full 100 watts to get out! 60-80 watts is aplenty! You should start at a low output, and slowly increase the output(while keyed up), untill the power supply starts to complain.(buzzer/light). This is what your limit will be. The only other cure, is a MUCH bigger power supply. Unfortunately, I cannot afford a 60-90 amp supply, so this is what I am forced to do to use the one we have. Also,keep your cb's output very low when using the linear amp. These amps are supposed to get a low signal from your radio, or the linear amp is overdriven. (noisy and unstable. Hope this helps you! 73's to you! jimsjinx
