Some of the frequency meters had a full complement of spare valves in spring clips inside the case. A TS-174/U (the VHF version of the BC-221) I used to own came with a full set of spare valves and a spare crystal. (That was a big surprise!)
There was also a post-WW2 official power supply with a stabilised output that was a drop-in replacement for the battery cage. Chris.

V T 7 6 valve
Hi Rod, VT76 is the same as 76 which has an octal equivelant 6 P 5 G also a rare beast. Good to see you have got it going. Re vibrator power supply problems, dont overlook thr buffer cap across the secondary of the transformer and sometims a second one across the primary as well.
