Surely that's the other way round? Hunts and TCC etc caps are usually axial in design.
These caps from Rapid (http://www.rapidonline.com/Electronic-Co...itor/71096) are by far the cheapest available and unlike a lot of radial ones their leads are a decent length too. You would need to go for the 400vdc ones. Next up from these are the pretty yellow caps that are available from RS, Farnell, the BVWS and JustRadios.
Ceramic disc capacitors are very cheap and are suitable, I recently ordered a load of these ones (http://www.rapidonline.com/Electronic-Co...itor/74530). They are rated at 1kv so suitable for replacing tone corrector capacitors. Most other caps can be changed for 400vdc ones.
For replacing caps across the mains X2 suppression capacitors should be used, and where a capacitor goes to an external connection such as a gram socket or aerial socket it needs to be a Y2 capacitor.
