"The other day, the right channel went out. I switched the leads going into the preamp and the left channel was on and the right one silent. I assume from that that my preamp is not at fault, but that there is nothing getting into it on the dead channel."

So you're saying you swapped the channels going into the preamp, and the silent channel stayed on the right side...... This means that the problem is likely at or beyond the preamp......

Several questions.....

1. Is your phono the only source of the system? Or do you use other sources? (CD/DAC, tuner, etc.)

2. If you do have more than one source, is the problem ever occur with other sources?

3. Does your preamp have the phono stage built in or are you running a phono stage ahead of it? (If the latter, the phono stage is likely not the problem.)

4. If your preamp has a built-in phono stage, is the phono stage on a separate card that is connected to the main circuit board of your preamp? (As opposed to being just part of the main circuit board.) Do you know if your phono stage uses integrated circuit chips?

5. When one of the channels goes silent, do you still hear noise out the speaker of the "silent" channel? Does the noise change with volume setting? When a channel does go silent, and you then cue up the cartridge off the LP, does the noise sound the same on both channels or stronger on one channel?

6. Does the sound tend to return when a loud passage is played?

It's hard to speculate the problem, answers to these questions will really narrow it down.
