I'm in my first steps of exploring tube audio and have acquired a very nice Eico tube tuner. I run the mono out to a Y patch cord that takes it into a Pioneer 60w amp's L and R tuner inputs; just as I do with the Pioneer tuner. The Eico sounds excellent. I was looking for a multiplexer to convert it to stereo but the mono has really grown on me. Problem is there is very little volume. I have to set the amp on a level that would blow my ears out if I was listening to another source at that level.1. My understanding is I need a preamp to get the Eico tuner vol up?
2. Are most of the preamps used in this sort of configuration mono?
3. Why does the Eico tuner need the preamp but my Pioneer ss tuner doesn't?
4. There will be three vol controls in the config: tuner, preamp, amp. How should I set them relative to each other?
Many Thanks! Sign me: Learning & Curious

My Sherwood mono tube tuner and also my Dynaco FM3 both have a gain pot ...on some tuners it's on the rear of the chassis
Don't know which tuner you have so I checked the specs for Eico HFT90. Output spec is 1 volt and seems to come from a follower that is fed by the detector with no additional gain. These tuners were intended to run a preamp TUNER input or a stereo decoder with some gain. I got a cheap Knight Kit stereo decoder for $10 and it was so bad I had to modify the design. Now it's less bad but still as good as the mediocre broadcasts.
So you need some extra gain. Perhaps you could replace the follower with a voltage amplifier using 6AV6 or 12AX7.
Usually you would set the tuner gain to max for best noise floor. I keep my power amp gain at max and use the preamp for gain adjustment.
