Hi

I have a Rotel RB981 (130W) Power Amp. How do I tell if it is high current? Thanks

The term "high current" is arbitrary.  Does it have a relatively massive (big/heavy) power supply?  Is it rated down to 4 ohms or better yet 2 ohms?  A "high current" amp should double the wattage as the impedance of the loudspeaker load is cut in half.  "High current" amps are of particular importance for flat panel loudspeakers.

My guess is it's sourcing about 3A at full power for single channel. That's typical for an amp that size with single pair output transistors per channel on ~40V PS rails.
