Tannoy Crossover Capacitor 1000V ?

Which drivers are these?

Unless you're using them as PA speakers, you should be fine with only 250-630V.

I would assume they are either the 3833 or 3836, the last person that owned them removed all the stickers/markings. There is no gold ring around the speaker, I think they are bit older, before the cpa15's I would assume...

This is a Tannoy supplied schematic, correct? I still find it odd that they'd recommend such high voltages. I believe my HPD's maybe came with 150v.

Are all of those caps in parallel?

Do you have a specific budget? Some brands such as Sonic Cap or Duelund can make custom sizes.

It was supplied by Tannoy, and is from the "System 15 MKII" drivers. I'm quite sure they are in parallel. No specific budget, what ever works well. I have a feeling it will be fine without the high voltages, I spoke to a tech today that has been in it for years, and suggested not to worry about the such high voltages. He said it was probably because Tannoy at the time had tons of those specific caps, and they just used those for cost. If you have any other input, great, and thank you!
