Are RN65 non-magnetic?
I've read reports that those milspec Vishays (RN60/RN65) are non-magnetic.
I have some on order and will try them out.
For power ratings, a 1/8W milspec is usually equivalent to an 1/4W "normal" one.

If you're buying from Shuro you can try the non magnetic CMF55-143 (or something like that).

As for caps, has anyone tried Panasonic FR yet? They're supposed to be an improved version of FM.

For my RIAA preamp I did use 66-RC55LF... from IRC, a bit expensive (around 1 euro) but very nice. Anyway, as said earlier, larger is better, avoid carbon, use metal, metal film (if you are poor (like me)), metal bulk if you are rich.

Conclusion is that we make the PCB suitable for 1/2w resistors...then it can be cost and performace vise optimized to what people belive is cost beneficial

A lot of companies make RC type resistors. I tried Welwyn and they are good too.
Anyway, we make place for 1/2W resistors.

Btw,
talking about non-magnetic.
Is it still fact for Gold plated PCB,
is there still a Ni layer between Cu and Au ?
If so, like in the old times, we'd rather not....

I am fine with tin plated copper and FR4. I like red and silver. That looks good to me.

Ok, lets go red with tin plated copper. Wow, i feel like i am at the controls of a big ocean steamer.
