another proof of concept

 

if you pester me long enough I will build it.

 

I guess I need to build another one.

Chicken or the Egg?

In keeping with the victrola horn theme.

I was always under the impression that the WE 555 came about based on the Victor Credenza.  In looking at the patents, the 555 was applied for first and also granted first.

 Both patents were done by the same attorney but the 555 was WE and the credenza transducer Bell Labs.  The firsty credenza dates back to 1925 so the patent is obviously after the fact

 

 I love the above treatment.

Just attach a needle to a diaphragm and play 78's and do I see a mini 16A hidden inside the box?

Mystery Horn Identified

A few posts down I found a horn that I was unsure of its intended use.  Walter pointed me to a similar horn and it all came together.  I was puzzled by the flat top and back and that the mounting flange didn't form a full circle to couple to the driver.

I now know the reason and I had everything upsidedown, because it wasn't meant to couple to a driver but to the above the surface parts of a victrola.

I have never really paid much attention to victrolas and from afar I just assumed those louvers were shelves to store your78"s

I guess you learn something new every day.

New York to Washington via Peurto Rico.

Another WTF shipping experience.

how the box arrived.

how it got that way..

Flea Market Find.

Found this while scrounging  for records today and it was just too pretty to pass up.

The cast (bronze??) throat adapter weighs at least 20 pounds

 The only makings 

an odd shaped coupling.

Must have mounted flat.

that it an oak horn.

and sounds really good given the source.

Empty Boxes and Blue Tape.

 A box came in today which I thought contained 10 batteries for yellow dog's bark collar but when I opened It I was puzzled to see what appeard to be a box of broken styrofoam.  Upon a little spelunking I realized the hidden treasure. (forgotten purchase)

 after peeling off the masking tape... yes masking tape not packing tape! I saw my favorite packing aid... the blue tape.

unlike packing tape...both the masking and blue tape easily peel off and the cartridge in need of a makeover is safe.... can't wait to take a dremel to it.

In contrast to this experience I just received an order from Mouser that had all of the panasonic TSHA caps in pairs and rolled in bubble wrap.  In order to secure the bubble every exposed surface of the bubble wrap was then secured with packing tape.  I used a band saw to open them.  Here is a good lesson.  Take a prized tube and wrap it in bubble wrap and then completely cover the bubble with packing tape.  Now attempt to open it.  If everything went fine, repeat with 10 tubes.  Eventually a tube or a finger is going to take one for the team.

If you must use packing tape to secure bubble wrap, use one small piece and fold an edge of the tape over to provide an obvious access point.

Thank you for reading this installment of Ghetto Packing & Shipping 101.
