Heartbreaker Reverb tank connection question

I need to remove the chassis for some pot cleaning and overall gut inspection but it looks like the white cable of the reverb tank is not your usual RCA. IT seems it is hardwired both to the tank and also in the chassis. The gray wire is just a regular RCA which one can disconnect. I understand that Mesa did this for idiot proofing the amp.

Any advice on how to disconnect the white wire. I also like to try out a new tank while I am in there because the reverb is a bit thin

strange - on mine you can unplug both wires, they do have different sized connectors

I have a Studio .22 where I can remove the white wire but not on the heartbreaker. It's like they crimped the connector
