I actually did do the test you put up.  I followed your directions and the continuity was all great untill I got to where I had one multi-meter lead on the "hot" blade, and other lead on the transformer wire.  The wire I was testing on the transformer was the connector that goes to the PCB board (there are 3 wires going to the board  2 reds (hot wires) and 1 black (ground) I was testing the red.  I know this is pretty hard to understand but thats the best I could put it.

I tested my transformer today and I'm getting resistantace from every wire but the ground wire (I tested ground wire to transformer case).  So I take it that my transformer is shot?

Hello, I'm new to this thread but I have a question about my Kustom KLA100 guitar amplifier.  Today I was playing through the amp and all of a sudden the sound started cutting out so I shut off the amp and unplugged the power cable,  I then plugged the power cable back in and tried to turn the amp on and it wouldn't turn on.  I have already looked at the following things and they are all fine, fuse and on/off switch.  So I don't have a clue what it could be, I do know how to use a multi-meter and have some knowledge about resistors, capacitors, IC's, etc.. Please help me find out the problem all help is welcomed.  Thanks
