Identify the positive speaker lead using the Super Reverb schematic diagram, if desired. Speaker polarity is not critical as long as all speakers are connected in the same way. This wire has four blade plug connectors along its length. If you are rebuilding the amp, use the soldering tools, additional wire and blade plug connectors to refurbish this wiring chain.
Connect each of the four connectors to the right tab on each of the four speakers, as viewed from behind the speaker. Use the pliers to create a snug fit, so the connectors don't come loose with vibration.
Repair the ground wiring chain as in Step 1, if necessary, then connect each blade connector in the chain to the left tab on each speaker. Using 8-ohm speakers provides a 2-ohm load when wired in parallel, as described.
