That looks like a great set to restore. Very smart design of alot in a small set. I bet it has had relatively low hours of usage based on it's chassis' appearance and having half Admiral tubes. Also, the CRT looks nice not having that burnt spot in the phosphors some of those oldies seem to get with alot of use when the ion trap(?) is messed up. The advice you will get here will have everything working as new
Is that little gray knob on the left lower side original? Seems like it should be color coordinated. I am thinking the big one on the right should match the main big one on the left?
