Any post war Television Repairmen here?

I saw this post the other day but didn't join in. I know that on these old TVs if you replace one component with a brand new part it throw off something else. The new part will function at a level that some other older parts can't handle (burning them out) because of their age.

REMEMBER - The old electronics can zap you and hurt you BUT the new electronics (computerized) can be zapped by you and you can seriously damage them!! The tables have finally turned!!
