Can you post up a link to a different builder for say a nice AB amp that does 10 & 11m that's not "crap" or "junk" as you put it?

The only builder I have ever saw do this was Peakaboo in the Joker amplifiers. He came up with and designed his own regulated AB bias scheme. He would even grind off component part numbers and values so no one would try to copy it. Best amp I ever owned.

Agreed. I am considering ordering a 400HD from Carl. The only upgrade will be switched SSB delay and class B bias.

You do not want the C400 or the CM400, they both have a driver final in the amp and would be considered a 1x4 amplifier. Those are usually considered low drive amplifiers. The 400HD is a straight 4 pill and will work better with many different radio's. (your Anytone radio's will do great with...

Tim if you check the date of this listing it's from 2012. This amp is long long gone and if it's not it's now worth 300-400 dollars easy. The reason you see red X's and no picture is he probably no longer belongs to the photo hosting site from back then.

You could do the same with a short jumper and barrel connector probably...

Not to rain on your parade but as you put it, you want 4-5 "pristine" Plus 3 B mics. You will easily be in the $800-1000 range for those mics. If you bargain hard in a year you might find 4 and be in the $600-700 range. The days of $75 minty mics are gone. Good luck all the same.

I’m not seeing 200 bucks there.

For old school amplifiers they have the bi polar finals that look like a giant pill. Like in the link below. https://www.rfparts.com/catalogsearch/result/?q=MRF454%2C+Motorola The finals in many radio's look like the ones you described. See below...

The finals look like white pills. In pic two you posted you can see half of one. Almost in the middle of the pic right below the white wire with the orange stripe.

That klv250 is very much a low low drive amp, that's probably why it keeps getting smoked. I'd put the RM3's back in and then have the owner run it with a 1.5 watt dead key and 10-12 peak. On SSB run 10-12 PEP. I would also put a fan on it and it should last a long time that way.

Probably be very similar to this amp on the video. It would be considered a low drive amp. Yours will be a 2 pill, hard to say what finals will be in there. You might have to pop the cover and look. mrf454, mrf455, srf3749, and if they have been replaced maybe sd1446. A pic of the inside would...

That works for a quick temp start. Something like an Antron 99, ten feet of mast pipe, and 30 feet of coax can get you going even better. I ran an IMAX 2000 on 20 feet of mast pipe on the side of a pole barn for 15 years with zero problems.

You might consider buying a newer radio to use every day and then buy some really old stuff to tinker with. The one you have pictured looks like 1970's vintage. I guess it might be fun but you will be constantly fixing/cleaning/replacing parts in radio's like that. If you can even find the parts...

The add says $300 shipped right at the bottom.
