Hi Dave

A properly restored 38-690 should deliver deep bass and noticeable treble - with the bass control set to max, and the Fidelity-Selectivity control set to maximum fidelity.

And, yes, a properly restored 38-690 will, most definitely, put any lower tube count set to shame, without a doubt.

I've owned one in the past...and had a few pass through here as repair jobs...so I know how they should sound; quite simply, SUPERB.

Thanks Ron,

I wish I had one to compare it to. If I turn the bass up all the way up and the treble all the way it does sound good. I just never thought one would typically play set with both adj to max.


Thanks Ron,
Dave

Correct me if I'm wrong. Most bass and treble controls on old radios only cut bass and treble they can't add any like newer equipment does. So having both wide open should give flat response. Keep in mind a good set does boost the bass at low listening levels. Also do to the 690's design aka bass amp bass would be greatly exaggerate at low listening levels with the control cranked.
