[Jukebox-list] Wurlitzer 2504 Keyboard Help

[Ron Rich]

Jim,
  If the phono has been sitting for a while, or has some contamination on those resistors, smoking is pretty common. I suggest that you check that you have the correct lamp in there and that the correct combination solenoid and resistor are being used (see the schematic). If all is correct, you may wish to sub 10 watt resisters in place of the 5 watt (which is what Wurly specs call for). Ron Rich

  I've got a W2504 in for repair, and have keyboard problems. The fuse was blown in the playrak, which explains why the keyboard was dead, and after replacing it, I've got the machine selecting just fine. I swapped the spring in the playrak to free play it. The problem is that the 85 ohm and 150 ohm resistors get real hot and actually start smoking after a minute. I disconnected the "make selection" light temporarily to stop the 150 ohm resistor from smoking. I measured 19 VDC across the 85 ohm resistor, and 10 VDC across the latch coil. Can anybody point me in the right direction? Thanks in advance,

Jim
