Glad your Champ is getting fixed Joe. Lovely sounding amps.

I agree with the comments regarding discrete components and tag-strip or turret board construction. Completely appropriate technology and a joy to repair (and make!).

However, integrated and modularised construction isn't all bad in the right place. It would be hard to post to Mudcat from a valve/tube computer, i.e. Colossus or ENIAC
