Nah, 250 will be quite okay - just for the fet gate stoppers in the new F6, so not at all critical but rather noticeable for the sound - thanks for this - I usually make these up from Manganin wire but the actual GR resistors are just that bit better, as you would expect.
Last time, I got these some of these from Rhopoint in the UK and they sent them out in a box - simpler to just pop them in a padded envelope, yes?

Perfect, I'll put down 250R. Now for the long answer about shipping...
An envelope is definitely more friendly than a box but may not be the best choice. At least for US post, anything that has variation in thickness over about 6mm, such as a padded envelope with parts inside, has to go as a package. For most destinations, package postage is the same up to about 200g, so a box costs about the same as an envelope. The box is also much less likely to get torn up in the various machines that move mail.
Last round I made up padded envelopes that fit around the resistors to make a first-class letter vs a package, which cut postage costs dramatically: US$1.20 vs $15-18. That worked great except for the one case where it didn't, and since a first-class letter can't be tracked they're just gone.
Happy to do it again, but I'd strongly suggest paying up for a package. I expect to send internationally the same way I've been sending chips - heavy paper envelope with the parts taped inside where the address/customs form is taped on the outside, with the whole thing fully wrapped in clear tape. This way if the machines eat the envelope at least there's some chance that the address and little parts stay together and might get to their destination.
200g means that a pair of 1862s can go in for no extra postage

Didn’t think about trying these Rhopoints as fet gate stoppers? I’ve used Takman Rex resistors in this location. Hmmm, maybe I’ll add another pair on my order, either 200R or 250R. Thanks James’s
Hi Vunce,
On the F6, another resistor that really makes a difference are the power source resistors - the original Isabellenhutte PBH 3W metal foil resistors (CuMnNi) - same material as the GR (General Resistors in the UK) in this Group Buy, thanks very much to Paddy
These are now known as Powertron FPR2-T218 - I think the Mundorf MREU30 ones are the same units but haven't tried them - there's another Powertron called USR2-R220 but is a NiCr foil, not Manganin (CuMn,Ni) at all - not cheap either!
There's another one called SHR-4 and is a different alloy - CuMnSn - I'd be interested to hear what the Sn (tin) difference would be in sound too, maybe if I win the lottery!
Notice, I'm not saying they're 'better' as my 'better' might be your 'yuck' -they're very detailed, quiet, smooth, but not 'slow' like some carbons, if you'll allow me my delusions!
