For what it's worth I gave the flask weights that an ebay seller from china is listing on ebay a shot. They are a little bigger in inside diameter and are thicker but fit the stock 300Bs just fine. The color is a bit more orange than the originals. Not sure if the thickness is more lead or just a thicker vinyl coating. The vinyl looks like ass, all drippy and lumpy. I was able to turn them to hide most of the bad stuff. What the heck, they look wierd anyway, right? I got them because I wanted to try two weights stacked on each tube. Does seem to reduce the sensitivity to switching a bit more.

FWIW, the new weights are 15g heavier than the old ones. They are also 27% uglier.

Actually the right one is 33.6% uglier.

Any photos you could share?

Dan, my Uglometer just got back from calibration. I know what I measured!

If you didn't loan it to Peebs it wouldn't get driven off scale so much.

Looks like your cooking a few sausages on there :)

Hi Aaron:
I purchased these:

Inner diameter of 43mm = 1.69 inches = slightly greater than 1 5/8 inches.
Question for you - in the Paramount Parts Swap thread you mentioned using a 1.5uF cathode bypass cap to roll off the Paramount at around 80hz. Boulos was wondering if that was too low. Is there a calculation for this? Thanks!

Thank you for the size :)
You miss read it Gerry. My sub woofers have a built in high pass filter. The signal chain is preamp to the subs (with HPF) then to power amp and speakers. Those frequencies are filtered before the get to the power amp. The 1.5uF size is what I have sitting around. There is a calculation for it but I don't know it.

You can buy strips of wheel weight material at auto parts stores. They are pretty bendy and have foam tape on one side. You would not want to stick it direct to a tube though. I am not sure how much heat the tape is good for. I have used it to add mass to a match rifle barrel, which get pretty hot but even if heat wasn't a problem, it sticks so well you may not be able to get it off. Maybe cover it with some Teflon plumber tape...John
