Hello hn702906,
Outstanding work!
Visited Taiwan (Keelung) back in Nov. 1978 during my naval service. Very beautiful and nice people.
I hope you continue to enjoy listening to music through your newly built amplifier.

I use new OMRON MY-4 series relay socket to replace old style connect wire and make sure if relay broken can easy to change.
