Sounds to me like a bad capacitor, but not sure. I would look inside for any slightly bulging capacitors or capacitors whose plastic wrappings have melted or shrunk or cracked (most caps are cylindrical). Please unplug first and be careful inside there and do not touch anything. I actually came across your post while looking for info on what I think is the same amp my brothers had but blew, and I was going to ask if they still had it so I could repair it. I've been very successful at repairing my electronic equipment such as Altec Lansing Model 95 speaker crossovers, power supply in Emu Emax II, and almost everything else in my studio.

Well, it seems you have your finger on the source of the problem. If accessible, try some tuner cleaner inside the potentiometer.

Why? Are you contemplating connection of something OTHER THAN A PHONO CARTRIDGE to it?
Be advised, only a phono cartridge should be connected to a Phono input. There's more going on behind it than just voltage step-up.

SOURCE: Denon pma 250SE phono problem
Denon PMA 250SE does not have a RIAA phono preamp.
for some info about these preamp and details here;
Phonopreamps.com Home Page
Note: Choose a better quality regulated power supply,
for these preamps.
Although an updated turntable with USB can be used
without the need of such RIAA phono preamp.
