Re: Jumping channels on 1950s Valco

So from what you describe re: output jack: cut the speaker wire and solder a plug on the speaker end and a jack on the amp end basically? Just wasn’t sure if the amp needed to see anything special because of the original field coil speaker…Hard to read the speaker stats but is it safe to assume the...

Re: Jumping channels on 1950s Valco

[mention]rebeat[/mention] : I repaired one of these in the 90's (actually had to rewind the field coil of the Jensen that was in it), although it may have been from the 40's and it was branded 'Premier' (the drum company). It is the same as the Gretsch Comet and many other brandings, which is like ...

Jumping channels on 1950s Valco

I’ve got an old 1950s Supro Comet (Chicago 51) with a 10” field coil speaker that sounds lovely when cranked. There are 3 inputs on back (2x instrument, 1x microphone). Can the inputs be safely jumped to bring about earlier distortion (for quieter home use)? I’ve tried to find info about this and so...
