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.
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.
For old school amplifiers they have the bi polar finals that look like a giant pill. Like in the link below.

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...
A local used the ham test online place and he liked it. I used and am using the below linked books to study. For me it was all about repetition, looking at the questions in the book over and over and then taking a practice test or two every week. You can create a user name and then log in to get...
It's a 25 dollar radio, nothing to solder or mod in those. Watch some youtube videos and have fun with it. If it breaks or you drop it buy another one. At some point you can look into a Yaesu or Icom HT radio. Much better quality and performance.
