LF: TRANSFORMER FOR AMP BUILD

I am looking for a transformer to build the kit I ordered from EBAY:
https://www.ebay.com/itm/Z-Tube-6N3-Preamp-TDA7294-Power-Amplifier-Kit-DIY-80W-80W/110605460716?hash=item19c09964ec:m:mjXMqEkOQncHNU5_tgavVjA

According to the specs they have posted, I need a transformer with the following specs:
2x AC24V-0-24AC/3.9A
1x 12V 1A
120W - 200W

I have contacted S J Andrews twice so far for a price on a transformer.
Geco recommended that I use a transformer as follows:
"150-300va (24-0-24) plus extra (9V at 500ma)"

Any assistance and prices are welcome
