Good morning all, I have purchased some Teflon wire rated at 600 volts. Is this suitable for rewiring valve radios? bowler

I use 600 volt rated wire.

I use silicon rubber insulated wire.
It looks like original VR wire but it doesn't melt even if you press a hot soldering iron against it.
It's also very flexible and easy to strip and to work with generally.

Ian,

Where are you buying that wire from?

I have a large qty of blue, brown and green wire from surplus factory stock. It was used in a product where we needed to run mains power alongside a heatsink that could get very hot if the amplifier was driven hard. Expensive maybe, but cheap insurance!

I've bought some other colours in a smaller thickness from Alibaba.

I dont like buying anything from Alibaba, wish temu etc. its 99.9% junk.

BETAtherm® 155 is a nice high quality wire to use. Tinned copper and available in different colours and cross-sectional area sizing. Class F flame resistant insulation.

I've been using the vintage-style 'pushback' wire, available from a few suppliers. It's easy to use (no stripping!) and stays in place when you bend it. Evatco sells it by the metre in a few colours.
