Default Pyle PLA4180

As soon as i plug the rca's into the amp it will draw excessive current..

All rca ground shieds from the jacks themselfs to the board are intact any suggestions?

With nothing connected to the amplifier, what is the resistance between the RCA shields and the B+ terminal of the amp?

Will it draw excessive current with no speakers connected?

With the amp powered up, including remote, what is the DC voltage on the RCA shields? Black probe on the amp ground and red probe on the shield, no RCAs or speakers connected.
