    I hooked up my V4 to two Ampeg SVT 210avs today. These are 8 ohm. I switched the head to 4 ohms and nothing. Switch to 2 ohms, it works. 8 ohms works. 4 ohm, amp is quiet.

    Issue with the switch? OT tap issue?

    More than likely you have a fault either in the impedance switch or the wiring to it from the 4Ω transformer tap. You need to take the amp to a tech. Do not operate the amp again on 4Ω until you do.

    Thanks. I switched it to 2 ohms and played on it for a few minutes but shut it off for good. I'll take it in to the shop next week
