Receiver Madness

Post by arpthark »

A lot of chatter about receivers lately. I'll add one to the mix. Found on a late 70s Mira(f)phone that has undergone a "reconditioning" prior to my acquisition.

What happened here?

I suspect I know just what was done...Of course I can't be complete sure (2D pic, etc.)
' too many words to type to explain...Most of my posts are too long, PLUS...I have a bad cut on my right thumb.

Are you willing to show the full front of the instrument?

I'll see if I can get one tonight. The leadpipe is definitely a replacement -- seems to be raw nickel silver, even though the other NS parts on this tuba are silver plated, and there is evidence of replacement. The receiver seems to stick out much too far. I have an original old-old Miraphone receiver (1950s?) here that I might see about getting installed instead of this weird cut-job.


Sorry about your thumb. I know it will impact your hitchhiking.

The thumb (though healing) is slowing down repair work, and that pisses me off. I don't hate repair work, but I like getting it done and going on to the next one, or going back into the house and practicing my euphonium Easter charts for a while, or going back into the house and taking care of paperwork, or going back into the house and eating lunch, etc.

Also - since I have to use that thumb anyway, I'm going through too many bandages every day.

Look at the loop that occurs above the first valve and see if you think it's as pronounced as with a OEM mouthpipe, and then consider the fact that someone could have cut the receiver off of the discarded OEM mouthpipe, drilled out some of the original mouthpipe from the back with a hand drill - but sort of screwed up, and then (perhaps, not particularly gracefully) stuck that pipe up inside the drilled out overpart. :smilie8: :thumbsup:

Wouldn't that explain both the extra overhang on the receiver end of the mouthpipe, and also what you're seeing regarding the receiver?

Yes, you may be right.
