Varistor/Capacitor identification | 19 December, 2019

Can any one tell me what I would need to replace this yellow disc. I have another board that this part has burned up, and I need to find a replacement. The manufacturer is Buss, however I cannot find any information with the numbers printed on it. The following is printed on the side: Buss M131 EL

I have also included a picture Thanks in advance for your help

Google capacitor code

Electrolytic capacitor M131 => 130pf +/-20%

Well yes except it's marked M1 on the PCB, suggesting it's exactly what it looks like, a metal oxide varistor or 'MOV' specifically one rated to 130VAC making the board itself an AC product that takes 110V input.

To replace, find any 130v varistor of similar diameter. The fact the other one failed suggests a large voltage spike such as lightning or a rubbish generator.
