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...

This is going to be used as a part of my base setup. I currently have a single 120 amp power supply for both my radios and amps but will be dedicating the 120 amp PSU to the new amp if/when I can get one. I have been using an RM Italy 27/586 low pass filter with both my KL203P (poor SSB audio...

I have an Anytone AT-5555N II and a President Lincoln II+ (V4), both purchased from and gone over by Scott's Radios. Do you think the following amp would be a good SSB choice for these two radios? I don't know if/why the optional 2879hg transistors are worth it for the extra cost but I plan on...
