They should be. In a Bakelite block there is no reason not to use safety caps. In some radios restuffing an original tubular might prevent installing the safety caps which are mostly a disk. In this case try to use the highest AC voltage cap that will fit. Also adhere to the new standard for these - which I think is no larger than .01. I have seen some large values used - if you like a tingle when you touch your set. Icon_mad

P.S. Check for a bad or intermittent volume control. DO NOT clean it with D5 Deoxit. It will be destroyed. If you have to, use F5.
