Part number GE H11AV brings up some parts in Google but seem to be variations so wasn't sure would be compatible. My analog board had quite a few faulty components when I received it, most likely caused by power surge. Have replaced quite a few parts already but someone who looked at the board suggested I should replace U3 as well so thought would be no harm. Hopefully one day I can get this analog board working again, seems almost impossible to source replacement 240v boards here in the UK.
