Troubleshooting a Wurlitzer 200a
Hey
I have a Wurlitzer 200a that has a problem I am trying to pin point. The unit seems to just shut off and lose power. It does not happen all the time but if left on not even playing the unit for 20minutes or more the unit just shuts off.
Anyone know what the problem could be ?

Thanks man
will do
would you have or know of a picture reference of that online ?
I also was thinking of ordering a new power plug thinking maybe
it could be that but does seem to be something loose
There was a wire that I was fiddling with that seemed like a ground
that was up near the left speaker that just seemed to be a bare silver wire
screwed down ?
Thanks for the help

Those pics are not of a 200a. They are for the 200, which does not have the fuses located on the PCB. I have a late model (1980) 200a, it has 2 fuses located on the amp PCB. I modified it with a kit sold by Vintage Vibe, puts the fuses in plastic quick release capsules. Very handy. No more having to desolder blown fuses......

It does sound like a bad solder joint somewhere. When the board heats up to a certain temperature the connection is getting pulled apart just enough to lose power.
How comfortable are you with electronics? Can you wait for it to die, and then follow the power line to wherever it's stopping? It should be a pretty quick find, but if you're not comfortable with it any tech should be able to handle it for you. Worst case it will be a component that needs replacing, not the whole board.

This would be my guess, or possibly a failing cap.Marc Alan Goodman wrote:It does sound like a bad solder joint somewhere. When the board heats up to a certain temperature the connection is getting pulled apart just enough to lose power.
