Yaesu FL-7000 , the BEST SS amp ever made and still available.

An Ameritron AL-800 would be an excellent choice.

A vague question as we do not know how much power you want to be able to put out.

Any amp will work with the FT-450. All of the newer amps simply require a keying cable from radio to amp. Older amps like the SB-200 require a relay between the rig and amp as the amp has a higher voltage on the keying relay. Unless it has been modified with the Harbach soft key.

I have an Ameritron AL-80A in line with a FT-950. Single 3-500Z tube. With 60 watts drive the amp has an output of about 700 watts on 80 meters (which along with 40 Meters is about the only two bands I use the amp on)

It will cruise along at 700 watts all day long, never get warm. The tube will last a long time if you do not abuse it. Nice desk top amp. You can buy used ones, or look for a newer AL-80A. For the amount you spend, even on a new one that amp is a good value.

I would use an FL-7000 , auto band tracking , solid state , built in auto tuner, no-tune. They cruise at 700 watts...

Hi to you all

Any amp will do.
I had a FT920 and on AL572B no problems.
I had a FT450 and used it with a AL572B no problem.
I have a FT857D no problem on AL572B
Now have TS590 no problem on 572B

But if You are planning for something like Alpha 9500 or Acom 2000 , I would go for AL82B and keep the change to upgrade your FT450D for a bit better rig.
Though I had a FT450 for 3 yrs I didn't like the RX of the rig much on both CW as on SSB.

But there is no reason why you could not make Legal Limit with the FT450D
I am rather fond of the single 3-500 AL80B now and that would work OK with the FT450D to.
Good luck with your search for your amp.
