The thickness of leads from Duelund resistors is 0.8 mm.
Siltech M20G7 is 1.5 mm thick
Mundorf silver gold is available in 0.5, 1.0 , and 1.5 mm thickness, with Teflon coating
Duelund is 1.0 mm , but looks like 0.5 of silver foil plus silk oil etc ( I don't understand exactly what it is )
DH Lab is solid silver ( doesn't say it is silver gold alloy ) .
I guess I may be better off going with Mundorf 1.0 mm silver gold .
Or should I be better off with Duelund ?
Thanks to you all for your response.
