[Jukebox-list] Wurlitzer 2504 Keyboard Help

[The Jukebox Junkyard]

    Jim,these resistors normally get so hot they will raise a blister on your finger. The problem with the lamp drop is the use of six volt bulbs with a 30 volt supply. The higher voltage bulb you use, the less heat the resistor consumes. I like to use a 28 volt lamp connected across the solenoid resistor. In this case it may behoove you to increase the resistor's value to prevent the coil from over heating.  BTW, the fuse in the playrack protects the coin switch coils only. If the box is on free play, this fuse is not used. Wes

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
