The same wattage should be OK. With carbon composition resistors, they all change with time, regardless of manufacturer, unless they are high stability ones which, over here at least, have an extra pink band....I use carbon film now, but metal film is OK. Whichever you have or maybe get cheapest.

A better investment is the absolute best antenna you can get up! A 4 element Steppir at 60 feet and 100 watts will do a lot better for DX than a G5RV at fifteen feet and 1500 watts.
Once you have the best antenna you can manage, then look at an amplifier. Remember, too, that an amplifier can lead you into RFI problems, so be prepared with lots of ferrites.

It is said, Jim, that the guy who has himself as a lawyer has a fool for client.
I doubt that it is more true than in the case of K1MAN.
Regrettably, the Feds will never get back the amount that he has cost them - as they say on the billboards advertising CalTrans "Your tax dollars at work".

I'm serously thinking about an Acom 1500 - one reason being that I have a couple of good 4CX1000 in stock. I've figured that I am now not in good enough health to do the building and the question before buying an amp is what the doctors are going to tell me about life expetency. The pension guys are giving me an 8% return on the pension pot which doesn't bode that well.....
Getting old is a sh*t, especially at 66..............just the alternative is worse.
But the Acom 1500 looks very good......and likely to outlive me.

A hot air paint stripping gun will get a 259 hot enough to melt the solder and then a 40 watt Weller will keep it hot enough for you to finish the job. It's also good shrinking heatshrink sleeving.

Also consider if you are a guy who changes rigs frequently or one who would be looking long term. Then figure how old you are if you are looking long term. If you're in your in your thirties and looking long term, then solid state is probably best but get some spare final transistors while you can. If you go for tubes, get some spare tubes, too, and swap them around every couple of years.
If you change rigs or amps every few years, it doesn't make much odds, although the SS amp with spare devices may well hold its value better - depending which one you get.
Unless you go for an autotune tube PA, it takes marginally longer to change band.....

It all depends on what you are wanting in terms of noise figure, gain compression point, intermodulation performance and how good the phase noise of the local oscillator is, since with high phase noise, the other parameters are effectively compromised.
