Title: Harvard 5F10 preamp grid resistor size
Post by: Diverted on January 15, 2021, 02:15:55 pm

Hi,

I'm going to start building a 5F10 clone soon. This is an odd one as it has three inputs@68K each. If I only go with two inputs, would I be looking at approx 40K each for the two?

Thanks,

Ted

I've got a bunch of 68k metal films in my parts bin so I'd throw 68k in there and not try to be too picky. ain't gotta be fancy with a lot of this stuff

Just stay with 68K and add a 1M to jack 1, tip to sleeve.
