You may have a shorted cap in the bass control circuit of your Pilot tuner. That would decrease the volume as the pot cuts in the cap. Do the other controls (volume, treble) work correctly?
thank you CV. on inspection found that the volume control has three pots in one. the first pot near the mounting nut has been rewired to the bass control. the bass control has been rewired to the treble control and so on so on.
do not have a schematic for this and probly would need a doner set to fix this. it seems to work fine as long as I remember that bass is volume. thank you
Some one might have Sam's 194-10 for your set.

hi Carl T called stevenjohson to see if he had one I could down load. he has it. looked all over for it no dice. have to call him tomorrow. maybe something im missing. thank you

Submitted herewith one nicely framed and reconstituted/regurgitated schema as needed . . .retrieved from archival storage . . .aka . . . "the mule barn" . . .and wrested from the voracious mouths of silverfish.
All magged on up a bit for clarity, due to the dismal condition of the original . . . . . . . now, I'm that a Mr Magoo type of reader would particularly LOVE that aspect.
It's all matched and mated together as a now UNITIZED schematic . . . .as the manufacturers info was being a split up, two pager.
I additionally . . . . pulled out my "crayolers" and done-did some mark up on all the pots.
The RED-Yaller is the Bass control which alters the response via the sliding transition between an .0047 to an .047 coupling capacitor inter coupling factor.
The Green-Yaller is the treble control which has a constant late stage passing off of high frequency audio via the .03-500k network to ground, with a variance of passing off early stage high response via the early stage .01 ufd capacitor to ground.
The Blue-Yaller is your conventional volume control.
The Fuchsia -Yaller is an attenuator adjustment . . . . . . should your phono cartridge have a higher than required input to the system preamp.
Its adjustment can permit reducing high cartridge input on down to the level that will equally mate up with the normal tuner detector audio output level.

wow thank you Edd. that helps me a lot. some one took great pain to change this tuner to some one else spec. there is a lot of things missing. just plain gone. yet it works great. im going to leave it like it is. thank very much. paul w
