Heathkit AA-1800 power transformer + serial number

I have a AA-1800 power amp that I am using with an AP-1800 preamp and an AD-1706 audio processor. The sound is unbelievable but over the last year or so it has developed a hum that is audible at low volumes and can be heard through my kef 102 reference speakers that I am using. I am pretty sure that it is the power transformer because when I open the amp that is where the hum is coming from. I was wondering what transformer is in the AA-1800 and where I could get one. Also, when I opened the amp I noticed that the serial number is 00009 and I am wondering if that means that it is the ninth kit that heathkit made of this model. Any information would be greatly appreciated. If anyone has a broken AA-1800 that they want to gut for spare parts and can provide the power transformer I would certainly be interested. Andrew
