Vintage Bell Sound Systems 3725B Vacuum Tube Amplifier. All 3 micros dial up as well as treble bass & phono. Highly prized by musicians looking for that unique old school sound lost on today’s synthesizer kids. Appears in decent shape for its age (aprox 1950s) cosmetically. Will need some tlc where wires go into unit, see pics. All orders processed very promptly. Thanks for lookin and jam on!
This is a LUX SQ-38D vacuum tube amplifier. Being a very old used item, it has scratches from use, please check the photos for the condition. The amplifier was previously used by a family member as a hobby, but has been stored in a warehouse for about 20 years. When connecting a PC to AUX-1 and connecting speakers to SPEAKERS L R’s 0 and 8? , sound was confirmed on R, but no sound was produced on L. When connecting a PC to AUX-2 and connecting speakers to SPEAKERS L R’s 0 and 8? , sound was produced on both L and R. When connecting a PC to TAPE and connecting speakers to SPEAKERS L R’s 0 and 8? , sound was produced from both L and R, but the sound was muffled and quite poor. Operation of PHONO 1 and 2 has not been confirmed. The MODE was tested in stereo only; other modes were not checked. The BALANCE was responsive.
Was ready to recap and rework as necessary and come up with nothing, plays great nothing gets hot no hum, all good. This piece is gorgeous. This one has Sylvania 6BQ5s.

Both tubes appear to have the same date code of SJ (although faint on one) which should put them as being from 1975. The print on these tubes is fragile and will easily rub off, much of the white print has already rubbed off, but the etched identifying number is still clearly visible. Although used, these tubes should still have some decent life left in them and are priced accordingly. The tubes’ test results are displayed in the photos (New 6550 Spec 100% =11,000 Gm). See the photos for physical / cosmetic condition. Notes Regarding Tube Tests. All tubes are tested on an Amplitrex AT-1000 tester in the automatic Fixed Bias Mode (for the most conservative results). Test Results are for a general reference only, and are not a guarantee of performance, nor a guarantee of how they will test on your tester. No real world (audio) performance measurements are taken.
