Hi guys... So- I am a jackass.
I just got a used xoxbox, and I was so excited. I played around
and realized that half the tact switches needed to be cleaned or replaced
and that it needed to be calibrated because it was awfully out of tune.
I have a multimeter and it didn't sound difficult, so I opened it up,
sprayed the tact switches with some deoxit (which worked beautifully),
used the trimpot to adjust the power supply to 5.33, messed with the
tm5 and tm4 pots till I had at least 2 octaves relatively in tune, and I should have
stopped there. Unfortunately I did not. I decided (after getting a bit stoned)
that I could do better with the tuning. I thought that maybe I had tuned it too low, and
that explained the major slippage that was still occurring, so I reopened it, tried again,
did a better job, and then started admiring the circuit board. I said to myself, "oh, how lovely...
Look there! Those resistors seem to be touching! I should separate them just a bit"
and whatever the hell I did, apparently killed it. When I applied power again, all the lights came on and
stayed steady and nothing had any effect. I tried find the resistor cluster again and looked all over
for another reason... I tried to tell with the multimeter whether I had loosened one of the ribbon cables...
I stared at it for like two hours, and now upon receiving power all the lights come on and then
just the tempo light stays lit steadily.
Any idea at all how I could start to figure out what went wrong?
I bet I blew up some chips or something as well...
Take pity on me, please. I would love to fix it.
Thanks in advance
