So this afternoon I aligned the 10K chassis. Those compression/plunger trimmers are quite the adventure to adjust. Well, actually, they weren't all that hard to do.
After completing the alignment, I reinstalled the mounting brackets under the chassis and reinstalled the Magic Brain cover on top of the chassis. Then I put the 9T speaker back into the cabinet, after which I installed the 10K chassis into the 9T cabinet.
By now it was around 4:55pm EST. I tried it out with my longwire. Distant stations were already coming in as it was getting sort of close to sunset here by then.
With the speaker (and radio chassis) on the workbench, it seemed to me that I was hearing some distortion from the speaker on loud passages. But in the cabinet, the speaker sounds fine. The fidelity-selectivity control of the 10K chassis really helps make this setup sound really nice. The 9T chassis does not have a fidelity-selectivity control.
Paul Philco322, if you're reading this, you will be interested in knowing that I picked up WBZ (Boston) on this set just before 5pm EST!
Photos (and maybe a video) later.
