Pyramid PA1000X Output Problem

Hello. When driving the amp beyond 50% on VU, the output shuts off, amp clicks and resets. Happened all of a sudden. Amp used in same configuration for past 2 years. Thanks.

    I don't think it's DC current leakage. It seems the overload sensors on these have a hair trigger. Mine will occasionally do it even at -20db. I have two other amps and they don't give me any problems. I didn't do my homework and picked one of these up cheap. I won't buy another Pyramid low power amp. It doesn't push the RMS110 watts either with out clipping bad.

You probably have some DC voltage leaking through to the output stage and the protection circuit is kicking in to shut it down. Look for a problem in the front end (pre-amp). If you are not familiar with electronics, expect a parts cost in the $30 range plus the local labor rate for repair.

On my kenwood VR-5900 twospeaker wires touched and the reciever clicked off now when you turn it on it comeson for a sec. then clicks and shuts off. none of the fuses inside areblown what could be the...


When the two wires touched the short overheated and blew the output transistor or transistors. The unit needs to be repaired or replaced. It only takes a momentary touch of the wires to blow the output transistor. It is not a fault of your particular amp. It is common to all Solid State amps. Tube amps that have output transformers are not susceptible to this problem. Always shut off the amp when connecting or disconnecting the wires.

Technics a900 mk2 amplifier cut out sound to speakers.


First of all, Marcus, you will need to check if you have blown off the speakers. Just remove and use a good 1.5 AA cell to test both the speakers. If ok connect and switch on. try to hear if the relay is clicking or if you hear any noise. If not disconnect, open the set and use a multimeter to check if the output had failed. Check on the sections only if your are familiar working with circuits or else it might not be recommended. Get help from a friend to check the protect circuitt and the main board for failure of the mosfets/ outputdrives. If you can reset the amp do so by keeping the menu pressed on swithed on. or keep it off for anout 12 hours. it will reset on its own. I hope this helps. Good day

Is there a ground peg on the back of the pyramid pr2500 preamp?


According to this listing I found on eBay it will work for you.

PYRAMID Stereo Control Pre-Amplifiers
PR2500

* Power On/Off Switch w/LED Indicator * Microphone Input Jack * Microphone Level Control * Bass/Midrange/Treble/Loudness/Balance Control * Master Volume Control * High/Low Frequency Filter * Stereo/Mono Switch * Muting Switch * Input Source Selector * Tuner/CD/Aux/Phono Input RCA Jacks * Tape Monitor Switch * 110/220 Voltage Switchable * Rack Mount Design * Dimensions: 19''W x 2.375''H x 8.5''DAs far as grounding the TT, if you must, just use any screw on the preamp chassis.

What is the power output in a power amp and is it expensive


the output transistors are 5 to 10 bucks each for most.there are 2 or 4 on each channel,depending on brand .some high end amps have 10 transistors on each channel.mosfets are a different story as they run 20 to 50 bucks each and there is 2 or 4 on each channel.some amps use a big IC instead of transistors.those have 16 to 24 pins and are easy to change. Those IC are 25 to 75 for a stereo one like stk4141 etc.since most yamaha amps are dc coupled,when the output transistors go,they take out the driver transistors as well.If you replace the outputs and the drive transistors are shorted,they will blow the outputs again.

My Marshall JCM 900 50 watt head (2500) has low out put


Did you replace all tubes preamp and power amp? Just a clarification I assumed so. Some common problems with amps in general are after time the effects loop relay can be going bad. This happened on my 5150. I eventually replaced the relay and all was fine but until I did I used a patch cable to go from send to return. Unfortunately this amp employs the use of opamps in its signal path for the EQ. You may also what to check these. First try the effects loop patch to see if that works for you. Since the problem is intermittent it sounds like that is the problem. If you need any other help let me know, I have pretty good experience troubleshooting/building tube amps.

I touched my speaker wire and my amp is out when i turned it on the reset trips


The output transistors are blown. This unit requires service. This is not a repair that I would recommend to a novice. Expect a parts cost in the $50-$100 raneg for this amp.

How to hook up a pyramid pro plus 4 channel pb-180px without using rca jacks for 6 by 9s


The pb180 has High Input receptacles on the back end. They are marked High Input and identified as Channels 1&2 left/right, and channels 3&4 left/right. You will need to identify all speaker wires coming from your head unit ( left front +&--) , and so on. You will be sending the speaker wires from the head unit to the pb180's High Inputs. In other words, the front left speaker wires(+&-) from the head unit will go to the High Input Channels 1&2 side, left input of the pb180, and so on, so the speaker wires coming out of the head unit will need to be cut. And LABEL all sets of speaker wires before you cut them! Then on the OUTPUT end of the pb180, you will be sending the wires back to the the respective speaker wires which are going to the speakers. So it's out from head unit to pb180 and out from pb180 to speakers.
Hopefully you have the plugs that Pyramid uses for the speaker wire inputs to the amp. If not you have to get creative, and make up terminals to fit into the input receptacles. Maybe a wire terminal from Radio shack will fit those pins..
Also, if you go on line: Google search "Pyramid auto amps" and click on "SEARCH" (upper right hand) of their Web Page. Plug in your model number like this, pb180, and you'll be able to download the manual for this amp. The manual has a full description of the wiring options.

Hope this was helpful and Good Luck!

Pyramid 14G power supply


Hi.
It very unlikely the voltage went down. I think you should re measure what the voltage should be yes it 13 volt is after the bridge you wil get this with dual 6.5 volt ac from the transformer, they don't change voltage unless you have a short at the output, and if you did you will blow the transformer, is your reading from 2 wires or is it three wires, output, the center to the end should be 6.5 and end to end maybe 13.8.
I would need to see the schematic to know what voltage you should be getting.
I wouldn't look on a bat transformer but ether, bad bridge or wireing.

I hope this help's

No right channel output


Feed the amp with the left channel preamp to the right channel input on amp and check output. If you get output from amp then pre amp nedds to be checked out if still no output then amp is suspect. Randy
