So I switched on my brand new VH4 and the mains fuse blew. I checked it over for any obvious faults and replaced the main fuse. Played it for an hour an all channels with no problems checked power tube fault lights and none where lit. What would cause that? I am an electrician by trade and I understand a short or excess current draw would blow the fuse but amps are not something I work on. I’d like to note that my amp is a 230v model and our nominal wall outlet voltage is 240v in Australia but can vary from anything between 230-250v depending time of day etc. Would it be wise to swap a couple of the transformer wires around to the 240v spec as per the service manual, or leave it as it is?
