I have a two month old Powermax PM4-120 amp PSU. I have a Carl Built 200HDC amp that can draw up to 46 or so amps. I also have several radios I use with it and each radio draws less than 15 amps. They are never used concurrently. Right now everything is connected to the PM4-120 via a...

So far I think you are 100 percent right to disagree. It definitely did not work well with the amp.

I ordered some Anderson connectors a few days ago and they are supposed to arrive tomorrow. The builder himself said this amp can be used with the Q5N2 and I was even running it at the same lower 30 watt PEP power level as the Lincoln II+. I based this on the dead key and PEP readings from my...

In my Anytone AT-5555N2 I see four IRF520s. One has N16K stamped on it, one has N17K and two have no markings. I have some other new ones from Vishay that are stamped N26K that I bought from Digi-key.com several months ago. Is there a reason Anytone would have three differently-stamped 520s or...

I do still have everything grounded and bonded after the exercise I went through a few months ago. The only thing I did was replace the KL503HD with the new amp. Nothing is soldered or spliced. The amp works fine with the Lincoln at 3 watt dead key and 30 watts PEP. I have not tried it any...

I may have another dodgy connection somewhere. I am occasionally having the amp seemingly lock on after I've un-keyed but only at the high position. It pretty much pegs the S-meter until I shut the amp off. I'll start tracing through this next. It seems like half the patch cables I have...

I did indeed.

Now I am working out the safe power levels I can run this at using my Lincoln II+ V4. It has a max dead key of about 5 watts and max PEP on SSB of 30 watts as measured on my Daiwa CN-901HP. This is the description of the stock amp I bought: 200 2 hg 2 x 2sc2879, Class C bias, low/high power...

Wow. I explicitly stated I am not going to open this up to fuck around with it when discussing extending the power cables. I don't care about the lights or a LED fan. I am a bit on in the years for that. I stated that the fan is loud and it is. Maybe the fan on your Carl Built is a bit less...

The info I posted was what was shown for the default amp configuration. Below are shown the as-ordered specs. The text below "Add To Cart" does not change when you select the optional transistors.

I definitely need to address the fan noise. It's quite loud. Maybe a quieter replacement fan, if there is one that fits, after the 30 day warranty is up is in order. Also going to relocate the amp from the desktop to a shelf under the bench. It's an open shelf in a cool basement so airflow and...

These look like they're just what the doctor ordered. I have several different crimpers but none that look like the one that is used for these. Yet. :)

Well, based on what I hear on my secondary radio the audio is clean. From the directions below I think 7 watt max input carrier means 7 watts dead key max but I'm staying more like at 4 for now. I need to spend some time working out where to set the RF power and mic gain on the Lincoln II+ to...

Splice was the wrong word for me to use. I don't have anything spliced. I should have said extended and any extension would have been 6 gauge using a terminal block. Turns out I don't have to do that either right now at least. I have a 120 amp PSU and 2 gauge wire running from it to a 150 amp...

I had a nice surprise arrive in today's mail. I do need to extend the power and ground wires before I can hook it up to my PSU though. It looks like the existing wire is 8 AWG. I already have a bunch of 6 AWG THHN lying around from other projects so I may just use it. I think it should be...

That "carcass" reference was a good one. Got a nice chuckle out of the imagery. I can transfer a new piece of electronic equipment into a carcass in record time.

Just what a bloke wants to hear very shortly after ordering a Carl amp. ;)

Well I took the plunge and ordered a Carl Built amp. Fingers crossed it works well. Now to figure out what to do about the KL503HD I have been tinkering with for the past few weeks. The extent of the tinkering was to replace the 9 mosfets. Are there any brave souls on this board that want to...

I just ordered an amp from Carl. I emailed him three separate times and each time I got a quick reply with the answer to my questions. Can't ask for more than that.

It sounds like given my requirements that I would be okay not upgrading to the C transistors. But down inside I can't count the number of times I have regretted not doing an upgrade as part of the initial purchase e.g. new car or motorcycle or snowmobile or, well, really anything. That said, I...
