Hello everyone I need verification on these few pieces to make sure that the blue ones are varistors I think the three bigger ones say JNC102w and the smaller blue one says 1021KV and the other little one I think is a diode connected to the source of IRFP206N mosfet and I have no idea of what to buy to replace it or what I could canablize it out of. Any input or recommendations would really be appreciated Thank you.
