You can probably find a 70's silverface for $700. If you have the dough, i always would suggest vintage. Better amps, point to point, easier to work on.
Also, for some reason i founf my reissue to be extremely tinny in sound. Other people here do like it though.
There is a thread just like this one, if you are interested in trying to get as close as possible with that amp. It was pretty recent, so it should be easy to find.
Not to mention tubes. The 65 RI will come equipped with a stock set of... whatever new manufacture tubes Fender is currently buying shipping containers full of... what is Fender using these days? Chinese/Russian/Serbian something-or-other.
A vintage amp will most often be well-taken care of by its previous owner, and often it will have had NOS tubes carefully selected for it in advance of you acquiring it, and/or been BF'ed in the bias-circuit, maybe even decent speakers if you're lucky.
And yes pre-1979 is a pretty good rule... although Fender still produced a few point-to-point models as late as 1986 (the mighty mite Super Champ being the last one)

What kind of guitar/pickups are you using? Did this just start out of the blue? Did it used to be quiet? Do you have florescent (sp?) bulb or a halogen lamp with a brightness dimmer on it in the same room?
Try plugging the amp into different outlets or a whole other house for that matter. A buddy of mine lives in an older house with old wiring. Everybody that plugs an amp in at his house has this problem. Bad ground or old wiring will cause this, but could be anything, but this is a good way to narrow it down between your gear and the power source.
to all, yes i have flourescents, but the grounds are lifted so that is not it. im using a gibson les paul studio supreme plus with stock pickups. ive tried all other outlets and its the same and its gotten louder than normal out of the blue... its especially bad when my treb is over 4 and i normally play it on 8 mid 9 bass 3 rev 3
