Old tube amp?

What tube amps from the past are worth looking at. I decided to give tubes another try and want to try an older design that will not break the bank. Keeping in mind inexpensive retube, don't want to spend too much when tubes need replacing. Speakers: merlin. Pre-amp: simaudio p-5. Present amp is w-5, and it isn't going anywhere as far as I can see. My system is completely acceptable, just want to have some fun experimenting. Had used a CJ premier four in the past, but my source is much improved and cannot say how sim's w-5 compares to cj's four.
Would like to keep it under $1000.
