I got it! I got it!

Congradulations on an excellent find! It must feel great to find your first roundie, especially a zenith in Italy! A 24MC32 chassis is a 1965 model. Thats interesting that they had a pal converter. Since the TV was for pal, I bet the chassis number is slightly different as it was not for the US market.
As for the 1V2 socket crumbling, it does happen. Its not from heat, its from corona arc. The 5KV at the pin of the 1V2 tends to arc to ground. This results in carbon build and breakdown of the bakelite socket. On my 26KC20, I lost focus because the carbon almost completely grounded the 5KV. Ive seen this breakdown on two zenith roundies.
