First of all, you need to play ALL David Bowie tunes when breaking something in.... : )
If you're going to feed a signal into the amp, you will need WAY higher power resistors than what i was thinking. My suggestions were based on letting the unit idle with no signal applied. I specified 16 ohm resistors as this would decrease the current delivery from the amp if a stray RF based signal "wandered" into the amp and was amplified. I should have also stated that inserting "shunts" into the amplifier inputs might be a good idea also.
If you are going to feed the signal from a receiver into the amp, the receiver would have to have preamp level outputs on it. DO NOT hook up the "tape out" to the input of the amp as it would smoke the load resistors that you install.
Secondly, you would need to hook up several low power resistors in parallel to handle a reasonable amount of power or just pick up two high power resistors. Contrary to popular belief, wire wound or "inductive" resistors are FINE for an audio dummy load. After all, the amplifier would be driving BIG inductors in a normal speaker system ( voice coils, crossover coils, etc...). Look for something that is rated for at least 10 watts apiece or rig up some 5 watters in parallel or series ( depending on what value you get ).
If you want specifics on part numbers, etc.. let me know. I'll do what i can to give you a list. Just make sure that the receiver does have the proper jacks before doing anything else. Sean
