just completed all the terminal checks and all readings are good according to the manual. once I plug in the power cord to the extension cord with the switch of the socket switched off the wall socket fuse jumped. all visuals soldering are solid and I wired the transformer at 219-225v configuration after measurement. anyone can help?

How did your power supply test go? (Page 52)
just found out only if te switch is flipped to power side the wall socket fuse won't jump. I have changed cable and rebuild the switch cable and what can be wrong ? can u check the photos? thanks very much.

You have a dead short to ground at the 3 position terminal strip at the power transformer. re read those steps and correct that.
IA, Breg, and OB are all OK on both sides but you have 1V at KregB? Those results are not probable.
It's incredibly unlikely to have 1V at a Kreg terminal and both Breg terminals reading correctly.
Can you just type them up into a nice list? It looks like you have at least one Breg that's 300V.
It's not a good idea to use an amp that doesn't pass its voltage checks. This can damage your amplifier and/or headphones.
