Vintage Synth Repair

i recently picked up a beautiful wurly 200a for free (the owners were 
moving, just wanted to get rid of it, lucky me!). other than the 
legs, it's in awesome shape, and sounded wonderful.

however, last night, i took it to band practice to show off. had it 
plugged in, a couple people fiddled around with it a bit. was working 
fine. then i tried to hook it into our board, to hear it through the 
mains, but that didn't work. i wasn't getting any signal from the aux 
output (tried adjusting the knob on the bottom). the headphone output 
worked, but it doesn't give much signal, and the sound isn't too good 
through that.

the worst part, though, is that while i was trying to do that, the 
internal wurly speakers started playing at a really low volume, with 
a distorted sound. a good bit what it sounds like using the headphone 
jack into an amp. even with the volume knob all the way up, just the 
acoustic sound made by the reeds drowns out the speaker, unless you 
stick your ear right to the grill.

upon checking it out today, the aux output is working fine, drives my 
amp. it's just the speakers that are not working.

i was connecting it to our board with a standard 1/4" cable into a 
line input, though at first i had it in an 'insert' jack, as it was 
dark in the practice room. the board is not providing phantom power.

anybody got any advice on what to check?

thanks for any help provided.
