Driver Crossreference

**Alien_Shore** · May 4th, 2012, 05:53 PM

I spent a bit of time consolidating specifications for Altec vintage drivers, since the info is fragmented and resides across many different web sites. Hopefully this will serve as a helpful reference.

As we get this software set up.I would like to move those charts to a sticky thread.OG mentioned a one stop shopping.Which sounds like a good idea where we can keep specs,schematics,plans,etc...

If you need help with updating/editing the charts let me know..

@Alien_Shore the moderated post was because of the attachments for a new member.That is automatic for any new member.

**Alien_Shore** · May 5th, 2012, 07:30 PM

Yeah, absolutely that is my intention.
I really like the added comments that Bill Eckle did on his xref, because it adds some great knowledge of the evolution of the designs, materials, etc.
And with Bill's passing (RIP) , it is unsure how long his pages will be around.

**Altec Best** · May 6th, 2012, 12:14 AM

I try to save as much Altec stufff as I can.

Courtesy of Mr. Bill Eckle.... And his passing was sad. R.I.P.

Here's one of his pages with lots of Altec stuff down the bottom of the page.

There is also a Driver and Parts Table that I had a copy of but cannot find at home or on the Net. Many members are familiar with it . Meantime I will keep searching.
