I am just finishing a nearly identical Admiral (chassis 20A1) at the moment.
That should be a much easier project than the CTC-7. Those chassis are laid out with plenty of elbow room, easy to work on. Admirals are well designed and they perform very nicely. Nearly everyone has success with them. These models are popular and well known to collectors, so if you hit a snag, advice should be available.
This article has restoration notes on my 24C15 console using the 20B1 chassis:

The only unexpected wrinkle was needing to replace the little mica caps inside the audio IF cans. This problem is not universal, but if you eliminate more obvious causes and can't get normal volume after doing the audio alignment, those two little micas are worth checking out.
In that case I removed the transformers completely, but in my current project I removed only the cans and left the transformers mounted in place. No need to disconnect and reconnect all of the xfmr wires. An even easier approach would be to cut the old micas in half from above using a wire cutter, leave them in place, and wire the new ones to the pins below the chassis; that eliminates the need to disturb the hair-thin wires on the transformer. Always more than one way to skin the cat
