I know that a database or a spreadsheet exists which contains all JBL informations. Does someone knows how to get it ?

I correct what I already wrote : I know that a database or a spreadsheet exists which contains some JBL informations about their vintage products.

Does someone knows how to get it ?

Hello All,

Mid Appalachian American here with what amounts to barn find L200s
that seem matched at 4.0 ohms, woofers move and rebound freely
under finger pressure. Cabs mitres are slightly open on corners, otherwise
very fair condition with the surrounds Looking tannish, no grill covers, but
the screens are completely intact.

Serial numbers: 17969 A & 17970 A

I haven't fired them yet, letting them acclimate
to my home. They were in cardboard shipping boxes for
ten years in an unconditioned machine shop along a mountain
creek bottom. Original owner claims they were fine before he
made the move with them and parked them.

It would be helpful and appreciated if someone could point me to
a thread were I can post pics and seek advise on how to best
check these out before I power them.

I am not an audio guy, (hence my plea) just a musically inclined
person seeking to build out a vintage system that will allow my vinyl collection to
impact my percussion and key playing children's souls to the degree it once did mine
with a long gone PX bought Sansui system

Thanks,

Lewdog

Hi everyone. I’m new to the forum and just finished some restoration work on the cabinets and woofers (new foam surrounds) on a pair of C51 Apollo speakers. I tried to upload a picture of my setup but am not sure it worked. They are looking and sounding fantastic. The refoam helped immensely and far more than I expected. It was the perfect project for sheltering in place.

In any event, I’m curious about when these may have been manufactured. The serial numbers are 4906 and 4954. I think it’s the S6 configuration with the LE75 horn.

Thanks in advance for any help or thoughts on this.

Hi Dazzlingmd,

we at this time have 21 pcs in the registry, but none of them with fabrication data.

yours seem to be some of the oldest with this SN .
the lowest number we saved was 53071

sorry

Thank you for your useful additions to the registry. IMO these components can be repurposed to greater sonic effect, as the N2600 runs the 075 much too low, causing sonic hell. I dismantled similar systems years ago with marine equipment suppliers in UAE , though in aftermarket cabinets. Your situation may be different, as you would probably get the most $$ selling these original systems intact.
