The inner tube used sucks, IMHO. Despite appearances, it is a standard bicyle tube that has been glued in with contact cement. You can carefully pry apart the halves, and replace it with a tube of similar size. IIRC that exact size is not easily found, nor is that weird English 'woods' valve. I replace a few with standard type tubes and valves, after drilling out the hole a bit. Be sure to get a Japanese made tube or US made one. They are much better built.

Agree on the suck quality of the inner tube. I'm sure it's got to be thin and very susceptible to dry-out and leaks-- for complex Audio Related reasons. Yeah, that's it.
Anyway-- you're really saying that it's a normal tube -- ie, valve on the inside of the circle ...? I've been patching this one for over 10 years now, and, though I've never had it out of the chassis, it just doesn't look possible that the Outward Valve arrangement is a normal cycle tube....
What do you do, get something way bigger and then manipulate into Inside-Out configuration ? And then glue it in that way ? Can't picture it ...
I'll take any hints you may have, though.
Thanks,
J.
I believe I got a slightly larger tube and started with inserting the valve stem into the hole (after appropriately drilling it out) you can arrange the the tube by folding it over as you flip over the rubber. I believe I folded over the two closest corners. That's the way the later heavier duty models have it.
Hardest thing was scraping off the old glue as I didn't want any 'spikey' residue left to possibly puncture the tube. Or yeah, you can modify the Sink too while you're at it. Later HD ones had a piece of MDF glued to the top plate. I know of some who shot in a bit of silicon fluid into the tube, not a lot, say and ounce of so, to further dampen the Sink's movement.
On my last repair, I didn't even bother to reglue the top plate.

Thanks for the details....
I'll see how I do with the Rep contact, and then start looking for new tube if that doesn't work out.
