I don't think you should power up this amp just yet.
While the resistance measurements that you're posting aren't a problem, there are major issues in your build. Many of your component leads are untrimmed and sticking out in random places. Most of the wires I see have too much of the jacket stripped off and this will cause problems. The green wire that's going to A9 with the bare butt joint making it longer just isn't OK. If that touches the chassis plate, you'll destroy the power transformer. The red wire going to the volume pot has so much jacket stripped off that it can touch the chassis plate, which will short out the right channel. One of your UF4007 leads also looks like it might be touching the chassis plate, which could also damage the power transformer. Many of the wires and components look like they are just slipped through the terminals and then soldered. It's important to attach these connections first so they don't slip around after soldering (this also lets you get the jacket of the wires much closer to the terminals).
Most of this could be cleaned up with a little time. The green twisted pair of wires may just need to be replaced, and it's a good idea for this twisted pair to rest against the chassis if at all possible.
