38-690 -- silent tweeters
#6

I suggest you recheck your wiring in the audio driver and output circuits. Reverse those wires going to the tweeters; whereas your blue wire is now grounded, lift it from ground. Do not ground the yellow-blue tracer wire yet. Make sure blue goes to green; yellow with blue tracer to white.

If properly phased, the tweeters should be wired, in series, green-white-green-white, as shown in the Tech Section of my website:

Try the set out.

If it makes a difference, you may have found your problem. Re-ground the return white wire from the tweeters, and the grounded end of cap (151), and try it again.

If it does not make a difference...I would begin to suspect the driver transformer (152). You may want to do a resistance check of all of the windings; making sure that none of them have any shorts to one another.

Edit: There should be no connection whatsoever between the woofer voice coil and the voice coils of the tweeters. This is beginning to sound to me like someone in the past got a little creative with the wiring.
