Subthumper Posted January 23, 2008 Share Posted January 23, 2008 Hi I've been asked to repair and amp and one of the valves is a 7025. I've told that this is the same as a 12AT7 or a ECC82. Can any of you valve anoracks clarify this or point me in the direction of someone who can? Its actually a guitar amp (Fender Quad reverb..a 4x12 100w combo...bloody hooooge) but does sound rather nice. Cheers Just Quote Link to comment Share on other sites More sharing options...

andy67 Posted January 26, 2008 Share Posted January 26, 2008 as above - but if you do not know what you are doing with valves - dont touch it! these things are lethal in the hands of amatures! Quote Link to comment Share on other sites More sharing options...

Defo not a job to do after a lunchtime drink. Quote Link to comment Share on other sites More sharing options...
