Things were going along great with this ca. 1929 Conn 32K I picked up recently... soldered some water keys back on, fabricated a patch for a pinhole in the third valve tubing, soldered a valve stem back on, PB Blasted the slides, and with penetrant and heat, managed to free up all but #2 (ancient lime-stuck, barn find tuba).
So, I let the #2 circuit soak in penetrant overnight and came back the next day and try to free it. The old brass ended up snapping clean and left one leg of the #2 slide inside the female slide tube, flush with the opening.
I'm gonna have to take this thing apart to get to that broken-off slide, aren't I?
tuning slide leg broke inside outer tube
