Reverb Tank - MOD®, 8DB2C1D, Medium Decay, 3-Spring

Question:
Aloha, I have a Marshall AVT20. The connectors to the existing reverb tank are not RCA. One plug is red/black and the other is green/black. What will the new connections be to replacement RCA connectors that I will need to add after removing the current connectors. Appreciate some help..., I'm just learning now since picking up this amp that didn't have a working reverb. MAHALO!! dan
