Chuck,
You are fortunate that you weren't more seriously hurt. Thank goodness! I like to dab clear RTV silicone sealant over any exposed HV terminals that I might accidentally get in contact with. This is an amazing HV insulator, and great at supressing corona too. It is even useful at 50 kV, employed properly.
Take care.
You don't suppose the reason the TRK-5 has a poor picture is because it is an old TV?
Man I'd love to have a TRK-9.
