Can anyone help me biasing a Jadis Defy 7?

Sounds like an extremely promising discovery, Matt! The "5w" undoubtedly refers to the wattage that the resistor is rated to handle, which is consistent with the shape you are describing (a power resistor).

If Brooks can't readily supply them, any major electronics distributor should have suitable equivalents. Digikey.com is one such place.

Good luck!

I replaced all 12 resistors with Jadis supplied 180 ohm resistors that came with the amp.

The Gold Lions still do not bias properly and measure differently from each other by more than double in some cases when the pots are set for minimum.

I put the original JJ kt88 tubes back in and had the amp biased to 4.5 volts in less than 5 minutes.

Should any brand kt88 be biasable in my amp? It seems that the gain in the Gold Lions I received is much higher than the JJ tubes.

I need your help to see if it is serious or not. 
I was adjusting for the second time the voltage, and putting 5.05v in all the four rows, and suddenly in the resistor I was measuring, a little explosion and a little smoke appeared, and the voltmeter show a value equal to zero in all rows, even the amplifier switches on the light and all tubes are light on. 

What do you think the damage is?

Why am I getting different voltage readings from each end of the fuse?
