Ameritron AL-811 Repairs – Popping Noise

K0PIR

I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

Excellent YouTube video and website. I was wondering if you or anyone has had issues with this amp with the IP meter dancing around? I can touch the meter, wiggle it, and the needle dances around all over the place. If I rock it back and forth it will sometimes function normally. Any help would be appreciated. 73, Marc VA7MNM at Yahoo dot com.

I just bought a brand new Ameritron AL-811 from the Denver HRO (4/2018) and, right out of the box, it’s making a loud snapping sound shortly after turning on the power. I sent a note to Ameritron tech support and they say it’s probably “one or more” of the HV filter caps but offer no help on a warranty repair. I’ll chat with HRO today.

Hi Rich,
Thank you for your comments and for your service to our ham radio community! I dropped by my local HRO shop yesterday and since the unit was a recent purchase, they advised that I return it for another unit which I did. The new unit is working fine. The fan in the new unit is also much quieter. I heard from Rob at Ameritron and he offered to help me troubleshoot and send any necessary parts. In the end, I am satisfied with the amp and the extremely helpful service at HRO and Ameritron. The folks at the Denver HRO are awesome!
Best 73,

I have and 811H ..it’s making the same popping as yours was. What is the best way to discharge the 4 capacitors so they are safe to change?
Thanks

Can you share exactly what kind of LED you purchased from amazon. I am having a hard time finding a comparable LED

HI Rich, Maybe you can help me with a question. I was recently given an AL-811 (not H). I am planning on selling or trading it so I opened it to see if it was clean inside before testing it. It looks great but there is a wire that was deliberately cut on the input board. Without taking it apart more I do not know what it does. Any ideas? I can send you a picture if you like.
