mopardave Posted March 18, 2022 Share Posted March 18, 2022 Can anyone tell me if there is anything available? What i want to do is use the CornScala for 2 channel/tube amp listening and front monitor av use and just be able to turn a know to switch speakers from one amp to the other when needed. Would be much nicer than moving cables around ever time i switch from one amp to another. Ya know what i mean? Thanks Quote Link to comment Share on other sites More sharing options...
Edgar Posted March 18, 2022 Share Posted March 18, 2022 Search for "audio amplifier switch box". Just remember that some amplifiers cannot tolerate their (-) outputs being connected together, others cannot tolerate them being connected to ground. EDIT: And tube amps cannot tolerate open-circuit outputs. 1 1 Quote Link to comment Share on other sites More sharing options...

Looking at something like this.https://www.ebay.com/itm/144038614764?hash=item21895ed6ec:g:Oo4AAOSw-7Zgneph Quote Link to comment Share on other sites More sharing options...

Some resistors of a few hundred ohms, permanently attached to the tube amp outputs, are often used as protection against accidental open-circuit operation. But basically, "Don't do that."

You just want to be able to play one or the other, without swapping out speaker cables, yes? Quote Link to comment Share on other sites More sharing options...

I was just thinking. Neither amp will be on at the same time, so no issue there. I just have to be certain that the tube amp is off when junction box is switched to AV amp. Now, what is a good brand junction box that wont degrade my signal? Quote Link to comment Share on other sites More sharing options...
