nah they still sell a lot of that stuff
remember they just dont repair cards but entire panels
theyre auth by GE to do so

look on their website listed above by doc
go to the catalog and see if the part is listed
then call up and set up a COD acct, ask for Pam
youll get dealer pricing that way (which is a substantial diff)
call them if you dont see it listed i bet they could help

if not start looking for second hand panels or convert it to a newer control (sx maybe?)

i did a google search on the TP and its avail on the net the pricing ranges wildly
transformer too

some of those sites might be selling through SMH though (old listings)
