Those little amplifiers are good eatin. I've already devoured about a quarter of mine so far.

Everyone knows what happened.

I just stumbled upon your channel, just the content I enjoy, Iam subscribing. Take care ! UDX-4570 Palm Springs wavin!

Ya. Over driven. Or waaaaaay to long winded. I've had mine for years. 5 of them actually. Run them right and they are great. Never had a failure

Something to consider if choosing to use kl203 even at recommended input levels they'll need time between keys for adequate cooling

Not being a snob but lol, the mosfet was open my friend maybe next time check them first before replacing the fuse. All the very best from across the pond.

Fuses rarely blow for no reason... The finals usually are the first thing to go!

Yep, always look into why the fuse might have blown before reapplying DC.

They are easy to overdrive. Yes, each amp should have an output video. Doesn't need to be long video.

Those 4 fet devices cost about $250 each, just replace them MR Tech! Great little amps!

I have ordered hundreds and I mean hundreds of those 10 out of 150 would be bad and you wouldn’t know it until you put power to it anyhow great video

Scott, I'm sure a lot of us (specifically ME) would love to see someone design a front plate or decal for this neat little Amp (I have 2 of them) that is 180° (upside down). About 98% of my mounting options are upside down and I would like to read the front panel right side up. Yes, I'm familiar with heat dissipation, etc., which is not a problem for me. I just need a panel that gives me that option and convenience. If not you, then maybe one of your subs might take on this project. I would be your first customer!

You should try Wago lever nuts for hooking up wires temporarily. They are good for 24-12 AWG wires and are easily removed and attached. The fuse blew for a reason. I would have used a current limiting power supply and brought it up slowly until I saw something happening. Reverse polarity on semiconductors, not good.

I have run a RM 203 for years with 3 different radios. I added a fan to mine to keep it running cool. I am surprised that it still works, to be honest, because i have abused that little amp. Sounds like the amp in the video had waaay too much power put into it. The hottest radio i put into my 203 is my Cobra 148, which deadkeys 3 watts swinging to about 20. Good little amps for the money.

I have the kl300p, is there a way to disable the preamp? If so, how can I do it? Thank you.

You would make your money back selling the remaining parts , case etc ..that's why the dead key has to be set inside the radio, can't trust a power level front control, too easy to make a mistake. SIMPLES ✌️ 73

I hate when the magic smoke leaks out of a device, good to know it gave up it's life to protect the fuse. 😂

if it was "shorted" it would still be making contact. It's OPEN

Hi all, are you still selling Anytone cb radios ?

Shoulda put a ground screw into each coax socket before powering it up with the radio attached. Having only the center conductor of each coax connected with no ground is a great way to make it oscillate and self-destruct. Quickly. We adopted the habit of placing a wattmeter and coax jumper between the radio and amplifier before making any tests. If the amplifier mimics a barrel connector and shows the low SWR of the dummy load, it's safe to apply power. And if there is any real mismatch with the power off, there is no justification to apply power to the amplifier until the "barrel connector" test flunk is cleared.

Until you look at finals hidden by board

you scratched the car body. It was enough to heat it with hot air

They just don't make burners like they used to. RM might be labelled as Italian, but they're made entirely from inferior Chinese components that don't last. 🤔

Would opening it up would that void the warranty?

Replace the mosfet

RM 3 ( proprietary) mosfets 520 to replace Same as the klm 60 most techs turn the lower values away not worth their time if you order from likes of copper electronics those RM3 RUN ABOUT 5 $ NOW LAST SET I GOT WERE ONLY 1.25 each All that work to open it the 60s you just slide the plastic bottom out

#19👍

Another cowboy wannerbe

I can't decide who's cuter. That little amplifier or Scott.

You are going OVER AND ABOVE, to support your customers, even when they have probably caused the problems for themselves. This is excellent customer service. Good work Mike!

Yuup one day mine smoked and no more

Reason i will never buy one. I will always run a old tube type mobile amp. 4 tube elkin mobile i have had for 40 years and never any problems
