Question about 3Com SuperStack II advanced RPS (662705388786) 100-Watt Power Supply
Have a tinny sound with 2 amps.Accoustic 140 and Sunn 200s. 3 bass guitars all sound exellent on other amps. All sound very tinny and hollow on my amps. Have tried many cords, had the individual speakers tested, they are perfect. On my amps, they don't move. Plenty of volume, but the slightest turn up of the treble knob on the instrument gives it a tinny, metalic sound. Switched the 2 speaker wires and it made an improvement. The speakers are jbl d140f in Sunn cabinets. They used to sound great. Any help would be much appreciated.
Both of your problem amps were made in the '70's or earlier. It is entirely possible that the coupling capacitors are failing. This is an issue for a service center whether it is caps or something else, like failing tubes.
The good news is that installing metalized polypropelene capacitors will make those classic amps sound incredible.

i say it can! u would get a nice clean sound! acoustic guitar sounds nice through a bass amp!
you probably wouldnt get distortion out of bass amp though! depends on the bass amp! some bass amps have built in effects! e.g distortion
