Hi my pre has been unplugged for month.It now wont power up.The fuses are ok,i do live in a area with hi humidity. Any suggestions would be good thanks.

There should be internal power supply fuse than. Also rectifier tube has to be inspected again.
It seems that tubes in ARC last substantially shorter vs. other tube amps/preamps.
Yes,ive tried different tubes.there is a external and internal fuse,theyre ok.Unless there is another one somewhere
Check to see if the line has a ground fault protection duplex on it. Could be in the kitchen or bathroom.
There's a chance it tripped and should be reset.
