repair or replace luxman preamp


1991 system, luxman tp 117 preamp, luxman dc 117 multi disc cd player, adcom amp, powering kef bookshelf speakers in small family room, and 3 rooms with luxman inwall speakers.  Preamp no longer senses remote, limiting source selections.  Repair or replace?  Replacement rec?  Thanks.

find a local shop - here, they charge $45 to evaluate & give a repair estimate


Are you sure the lack of 'communication' is due to the pre, could it not be the remote?

or maybe a universal remote could be programmed for your unit

or... replace the entire pre-amp
