suitable/optimum resistor types for grid resistor.

Any recommendations, especially if there is some reasoning behind it.

Thanks,

Jim

If it helps i recently replaced some in my S.E.X. amp with these, http://ie.mouser.com/Search/ProductDetail.aspx?R=OD221JEvirtualkey58810000virtualkey588-OD221JE, i think they are the ones supplied in the kit as they physically looked identical.

Hi Mark,

Thanks for the link, but what I'm really looking for is a discussion of what types of resistors are most suited for use as grid resistors, and what properties make them so.

Kind of like it is generally preferred to use carbon comp resistors for grid stoppers, but other types will work, and some are to be avoided, and the same for cathode resistors.

Sorry for not making that clear,

Jim

Grid resistors pass almost no current, maybe look for the one that was least antenna like ...John

I would think that an inductive resistor would help;the higher impedance at high frequencies being a good attribute.

Then you may unintentionally create a resonance with the resistor's inductance.

So, i did some research on this subject abd bottom line, as if it's any surprise, just go with what bottlehead supplies. ;-)
