I made an unexpected purchase from the tent sale. The above mentioned audio amp/base for use under a CRT monitor.
My wife uses a laptop and has been attaching a pair of powered satellites for in-home use.
When I considered what PE was offering at the tent sale for $4 with discount I threw one in the basket with a "not much to lose" attitude.
I've hack it up and spliced 16 ga. speaker wire to the leads and have it running the Mules now.
Much better than the black plastic boxes she was listening to.
Rack one up for the speaker builder in the house.
