I used to have the 25/25.
they do run pretty warm, not sure if its possible or not, but before you buy can you check the main filter caps? If not, then you have to assume they may need some work.
you can buy an ESR meter pretty inexpensively these days. a quick read will tell you if those main filter caps are shot or still good.
if you buy the amp, you may want to set aside some funds for new caps. they are not cheap and the newer caps are likely to be much smaller in physical size than the originals, so some crafting may be required to get them installed and wired up.
