[R-390] Bristol Screws for R390 Knobs

[Scott, Barry (Clyde B)]

A few weeks ago, I sent a post telling about a guy who has some Bristol-drive set screws for the R390[A] knobs.  I ordered a couple of sets and it turns out these are not the correct thread size.  They are close, but not quite right.

They were advertised as #8-32 but I don't think that's what they are.  I haven't measured either screw yet, but I have a feeling these most likely are a metric size that is very close to #8-32.

At any rate, if you are thinking of ordering these for your R390, they won't fit!

My apologies, but I was led to believe these are something they are not.  Needless to say I will be contacting the seller.

Thanks,
