Found out why my alc pot is not working. The guy I sent it to for alignment said he dis-abled it for more modulation on ssb. He said the 2510 can stand having this done but most radios can not. He also said they just don't have enough adjustment in that circuit and when you cut it loose on a...

A friend gave me his 2600 to look at that has no receive. It acts like the speaker is not working but you do get static on fm so the speaker is working. Any ideas?

Anyone have a Lincoln radio they want to sell?

Correct pot it is labeled alc, vr104.

Trade you a nice Emperor for your Lincoln.

I was going to turn down the ssb power a tad on my 2510 but is seems to have no effect on power out. Anyone have any ideas. I need to check the pot maybe it has gone south. I could before vary the ssb power with it but not any more.

I have not heard of the diode front end fix, have heard of the 455 mod. I have one 477 but have three radios that use them. Were is the info on the diode mod for receive?

To be fair he said 35 to 40 watts would drive the 2 2879's just fine. I see about 35 watts pep and it did do about 25 to 28 before. Sometimes you can see more if you wistle or something but just normal talking it does not do 35 to 40 maybe 28 to 32 or so. I may still turn the alc down a bit to...

I only run the amp on medium setting and it shows about 200 pep. That is plenty and have talked all over the country that way. I just got this radio back from the tech and before it only produced about 25 to 28 watts pep now it does a little more.

hr 2600

It is a Cobra xl350 and I think it is ab bias. My radio does not have adjustable power just a mic attenuator that does cut the power down somewhat.

I had a tech that was trained at the National Radio Institute in Washington tell me something I wanted some other opinions. 35 to 40 watts PEP on SSB into 2 2879's will be just right. Dead key on am is watt kills amps not the modulated power like on SSB. Does this sound reasonable. I know he is...

I watched a few videos on Utube with people talking on there Emperor and all had the display dimming like mine. My tech said they fold back the display power a small amount during transmit to feed more power to the transmit circuit. I thought that was odd but after watching Utube videos I guess...

That is why I bought one to have for my 2510, 2600 or Emperor just in case.

yea that Eleflow is a good replacement. just a little less power. I guess some people don't know what radio's use these besides a Jackson.

I found a place that has the mrf477 for a decent price. I think it was less than $40 shipped and is the real deal not a cheap Asian made part. I bought one just in case and they are getting rare and real expensive. The place is called Mobile radio store and you can order online. There is a few...

Hot Rod does your display dim some on transmit? I think some people form an opinion on one experience some times and never give something another chance. I am sure all brands have sold a few radios that had issues but the majority may not have that issue. Like cars, some are good and others just...

The tech emailed me that he finished up my 5010. He found a bad cap that was causing low power out and some of the display dimming. He said the display dims out on all of them some what because of the design of the radio. I don't remember my other one doing that but maybe it did. He has nothing...

I emailed them about minimum orders and you must buy 10 so that shoots that idea out. Free shipping they said but that is 70 bucks worth. I don't want a lifetime supply.

What was the issue with the one you bought? Making that type transistor is not rocket science, much easier than making a CPU or IC chip. Power transistors should be an easy make. They are not Motorola and don't claim to be but with the price of a Motorola if you can find one for 50 bucks or more...
