I just received my new Power Genius XL amp on Friday 3/29 and set it up today 3/30. when I started the amp for the first time I had no display and the standby and operate button does not work. The back light LEDs do not work. Any ideas.

Dennis,

The power supply was likely dislodged by very rough shipping. If you’re comfortable doing the following then this should get you going.

1. Unplug the unit
2. Remove the top cover
3. Looking at the amp from the front on the right side is the power supply. It plugs into a connector and is held in place with a clamp. Loosen the clamp and reseat the power supply in the plug. Tighten the clamp. That should get you going.
4. Plug in the amp to check if it is working. Keep you hands out of the amp while plugged in.
5. Unplug the amp and replace the cover.

The power supply becoming unplugged (internally) is a rare event but it can happen if UPS handles the amp roughly during shipment.

Please let me know if this gets you going. I’ve been using this amp for 18 months and it’s rock solid. I began testing with the first very rough “prototype” version of the amp all the way through the production amp.

Check and make sure the power cord is firmly seated at the amp. After reaching around the amp to turn the power switch on and off I've unseated the connector a few times, Another reason I keep the switch on now.

Mack thanks for the response and this is what I found. 

1. Ribbon cable at the front of the amp had come off.

2. Only one screw was holding the power Supply bracket and power supply had slid almost off the connector to the back of the amp. 

This was not from shipping but from assembly and poor QC. The person putting this amp together used a power screwdriver and sucked the nuts through the power supply bracket. So far everything else looks ok and everything tested ok with one concern the SWR on the amp is higher than my HF-Auto. the HF Auto shows 1.1:1 and the amp is showing 1.5:1 this could be the tuner however my 6500 is showing the same as the tuner.


I am still been very happy with my flex equipment until now and this may be a one time thing and one person working the line. Flex need to review their QC and I'll be calling them tomorrow to discuses the issue I had.  

See photos below and thanks.

Hello Dennis,

On the picture it’s clear that the PSU bracket was deformed by a strong hit.

I say this because the holes power supply bracket are deformed. The nut went trough the hole and ripped it open This evidence points to the PSU being properly mounted in the factory.

The ribbon cable from the front panel was disconnected due to a hit in transport.

On the picture you can see the bracket mounted onto the PSU.

The damage was caused by a strong hit in transport. The unit was likely upside down so the PSU (it weighs of 3.5Kg or 7.7lbs) deformed the bracket due to extreme force. It takes a tremendous amount of force for this to happen. So much that it’s hard to imagine. The material is 1mm (0.03in) thick.

It is my opinion that the unit is very robust and packed well since nothing else was damaged.

We will upgrade the PSU bracket for future units by making it thicker.

Thank you for the response and the more I look at it, it seems to have been dropped in shipment. FRS said they will send me a new bracket once that get them in. so far the amp is working great.

I have run the amp every day at full power for 2 to 3 hours on SSB  with no problems. I have always gotten great service and support from FRS and they offered to replace it if it has any problems and so far none. They will be sending a replacement bracket I can install. Now that its been two weeks and all is running fine I don't think I need to send it back but will call and request an extended full warranty, that would be a fair resolution.  I can say this amp is built like a tank and I would recommend it to anyone looking for a legal limit amp. I give it a 11 out of 10 so far. however I give UPS a -10 out of 10. I get better service out of the US post office.

Dennis,

I’m pleased it’s working!

The Flex engineer who does the final QC is a EE and master technician with 35 years at Motorola, I assure you there is none better. This was an issue with UPS shipping.

You’ll love your new amp!

73,

Mack

The metal looks thick and strong, I don't think it would be possible to draw the nuts through the metal to a flat surface. Also looking close were the nut is that you can see it looks like parts have pulled away from their intended place.

But if the unit was banged hard then the nuts could pull through the metal from the power supply weight pulling away from the bottom plate.

Flex will be very interested in hearing about this.

Bill why you ALWAYS talking like an FRS employee - and that in every thread. In every thread. Every problem for you is never an FRS problem and all other guys are idiots!

You have for all problems an answer. Sorry for me your a BlaBla maker or Dr. i know everything.

I would normally agree and I have the greatest respect for the flexradio team  but this could not have been UPS as it was missing 2  nuts, washers and screws and I checked inside the amp to make sure they were not floating around. If you study the photo its clear the nuts were pulled through the aluminum bracket. Also I didn't say the box it was delivered in was in good shape and showed no impact.   

Again thanks for the help getting up and going

Whoa .. you spent $7k, waited 2 years, and now you want an amp that actually works when you plug it in and sit it on the shack desk?

Ranko, thank you very much for your responses!  The PG XL that you designed is first class, and I’ve enjoyed every minute of operating it.   I am impressed by the engineering.  It is indeed built like a tank!  I’ve made a few “operator errors”, but the amp’s built-in protections worked as designed and protected it from my mistakes.

Those pictures are a little concerning.  In Flex's last email about the amp they said there had been some quality control issues.  Hopefully this is an isolated instance.

The quality control issues mentioned in the letter were about some amps not meeting performance specs,,,this has nothing to do with that.

In the first picture that horizontal piece of metal below the ribbon seems to be badly bent where the screws are. This would seem to show that they were turned much too tight or that the metal is very thin and flexible

Looking at the first picture, it does seem to me that the components were pulled apart – like if the amp was dropped several feet upside down.  If the box was dropped squarely it may not show any damage, while the internal assemblies of the 30 lb. amp could been damaged by tensile force, and missing screws could be lodged out of sight.  Just my guess of course.

Dennis sorry to hear about your damaged PG-XL.  Given the wait time and cost involved, that's sickening.  While I'm glad you were able to affect repair, hopefully FRS will make your amp 100% right for you.

Hopefully FRS will take better packaging steps to insure future PG-XL shipments can survive the UPS shipping process.  In certain cases hard drops, hard enough to cause hardware to rip through metal also leave indications of crushed external packaging.  One thing for sure.  If mine shows up in such a condition or with loose rattling parts, I won't accept it from UPS.

The only problem is, UPS won’t let you open the package unless you accept it. So if the box looks ok, you won’t know until it’s too late.

Both my Alphas were shipped in two boxes with transformer separate from the amp deck.  I had to install the transformers.  I am sending a KPA500 back to the factory and Elecraft recommended that I remove its transformer before shipping.  Seems like a prudent approach.

Unacceptable.

I would be asking for either a replacement amp, or a full refund. Look how scratched up the area is. Who knows what else may have suffered such forces. If in fact it happened in transit between you and FRS.

If the outer shipping container looks fine, I’d be asking FRS some serious questions.
