I just bought a k8042 kit (symmetric 1A power supply) and it was pretty easy to assemble. I have a 2x18 VA transformer (i measured 20v ac when not connected). But when i connect it to the kit, the transformer heat up a lot, and the regulators too. I only have 7v in Va and Vb.
Somebody can help me to find if I did something wrong please?!
Thx a lot!
