Hello,

Trying to revive an old ALDA-103, and need a replacement dual-speed ball drive for it. Hopefully someone has on in a junk box somewhere!

I can order a new one, but I'd rather recycle a used one if possible.

I'd also be interested in any Alda 103/105 parts, or complete rig if the price is right.

Please feel free to contact me if you have questions.

Thanks!

Alan Barrow

Another option is Oren Elliott Products (OEP)
http://orenelliottproducts.com/index.html

OEP was the original supplier for many Heath capacitors and planetary drives.

Oren Elliott Products, Inc. is the largest US domestic manufacturer of air-dielectric variable capacitors.
Producing capacitors since 1925, the OEP Plant I was first known as American Steel Packaging Company and then as All Star Products. In those early years, their applications and major products were almost exclusively focused on the broadcast and short-wave radio industry (which was a huge market in late 1920s and 1930s).
During World War II, ASP supplied the Allies with 3500 capacitors per day, and by the end of the war the company was the world's largest producer of air trimmers.  In 1983, Oren Elliott Products Inc.'s was created and expanded into new facilities (Plant II) to include CNC lathes, CNC vertical machining centers, CNC and conventional Swiss screw machines, and all of the support equipment necessary to enable OEP not only to produce all of the machined subcomponents for their capacitors.

If you have one, but it needs repair, you can prise them open. My expereince has been that go lumpy from the grease drying out, and a good clean and repacking with some light grease and reassembly works. If the balls have gone rusty, then you need  to replace them, though.
