This is the solder burn proof jacketed wiring. Spec sheet and wire have 150V rating on it, but it also says that it meets MIL-W-16878E TYPE B which is 600V. Is this safe to use in tube amps, voltages up to 500V?

My 1981 Alpha catalog, lists it as MIL-W-16878D TYPE B and 600 Volts.
Numbers 7149 through 7163 carry the 150 Volt rating.
I suspect a typo.

This is the response I got from Alpha Wire:
I apologize for the confusion. 150V is printed on the wire because the UL and CSA approvals are for 150V. So if you are using this in a UL or CSA application, it can only be used to 150V. However, the MIL-W-16878E approval on this wire is for 600V. So if you are using it for an application outside of UL/CSA, it can be used for 600V. The reason 600V isn’t printed on the wire is because the Military specification does not require printing, while the UL and CSA approvals do.
