which chassis was the best ?

[Zenith26kc20]

A RCA CTC169 has been one of my favorites since they came out. Love the picture when the CRT is good. Power supply caps were a problem as well as the tuners sometimes. I always marveled at the vertical stage in that set.
I personally liked the dreaded Sears "Warwick" solid state once I got used to it. The owner of the shop where I was at the time literally hated those sets!
Also liked the Motorola chassis that used the "JA" panel.
