More progress, but my polishing wrist is starting to ache!

Only one more trim piece to go, but it has a dent. What's the best way to pop a dent out of these things? I'm tempted to leave it be, and install it up top where it will be less noticeable.

I'm glad you mentioned that. The bottom trim piece on my CTC-7 has a couple of little dents, and I was wondering how to deal with them. I just trotted out to the shop and confirmed that the top piece is perfect. Problem solved!

I don't know if it is just me. But I cannot see the dents!
Can you highlight them on your photo?

The dent is in the last piece, which is currently soaking in vinegar. I'll post the dents tomorrow, they are very noticable.

Here's a shot of the trim, all polished up now! The dented (and bent) piece is up top, it's not so noticable now. It will be livable till I can find a better one. Also got a wild hair to polish the CTC-4 stuff, since I never did any clean up to it. Sure looks nice in it's new digs in the living room.

Ugh ! That trim piece is AWFUL ! RUINS the whole thing ! For SHAME !! Box the ENTIRE set up & send it to me, & I promise I'll dispose of it so it'll NEVER defile anyone's eyes w/its hideous ugliness again...(grin) Lemme put it to ya this way-If someone offered me a brand-new, TOTL Mustang w/everything you could get on it, or one of your TVs, I wouldn't hesitate an instant. I'd grab the TV so quick it'd make yr head spin...

I use a spoon shaped dental tool from the back side of the brass trim piece. Place the front side of the brass trim against a hard flat surface like your kitchen counter top. Use the spoon shaped dental tool to press against the brass and move back and forth over the dent to to flaten out the dent against the hard counter top. This brass is very thin and is easily formed back into place with a small amount of pressure from the back side. This is a method similar to the way auto body mechanics straighten a dent using a dolly and a planishing hammer. The counter becomes the dolly and the dental spoon is your hammer (but you don't hammer you just apply pressure and slide the spoon back and forth)

I was able to almost completely remove 2 small dents with this methodology, and you have to look very closely now to find them.

Good Luck!

Operation 'I hate 21-CT-55 peaking coils' was a success, but it remains to be seen if the new ones will do what they are supposed to.

Slowly powered the chassis on the variac (how did I ever troubleshoot without one?!?), and only got 20 volts of B+....

Predictably, both of the caps in the doubler are almost completely open leading to very low voltage. Jumpered one of them with a new cap, and got almost full voltage and a decent looking waveform out of the horizontal oscilator!

Now the recapping begins...

That leaves me with a lingering question though: why on God's green Earth would the PO have replaced almost all the caps in this thing, only to not replace the ones that matter most? I always begin with the power supply when it comes to caps, but it appears the opposite happened here.
