OK so one of my 802-8Gs is not working anymore... just stopped during *moderately* high level playback this afternoon... :banghead:

opened it up and the leads to the diaphram are broken.

Is the fix as easy as repairing/soldering the leads so that there is a connection again? Diaphrams do not appear to be breached (no obvious signs of light shinning through)


Thanks a bunch....

Might as well get a new diaphragm! They advertise original Altec diaphragms in both 8 and 16 ohms!

Price isnt too bad!

Are you saying the wires from the drivers input terminals to the diaphragm are what broke?

That you can fix!

I tried. The connections from the terminals to the coils bend 90 degrees. I thought I might be able to fix/re solder but the leads are very fine and the insulating material- phenolic or something- was in the way. Eventually I moved on and had the diaphragms replaced. Besides, I sensed that the other leads would soon break and I was not prepared to mess with all of them.

Oh, the very fine copper strand into the diaphragms VC! That you cant fix!

will I need to replace the copper strands or solder them so they again have a connection?



Thanks again...

In the meantime, I am listening to 802Ds

I think I like the Gs better...


Probably will pick up some diaphrams for future use... seems like a prudent move...

thanks for the link (and advise)

Is the 90 degree bend at the connection stock? I thought I had read that the 90 degree bend was indicitive of over powering.... IE the bend comes just before the break in connection.... but I can't seem to find that post....

Can't confirm since I did not keep the old diaphragms. They do have to curve over 90 degrees to move from the terminal to the voice coil, old or new. Is there a difference in the radius of the bend over time that causes more tension and a tendancy to snap? Don't know. Took the extra effort to send the drivers to Great Plains to get them re-magnetized, just in case. A little under $200 for the pair plus shipping out, but a good investment for me.

found a simmilar problem w/ 604s on the altec users board...

here is a link....

long story short -- can be done, effects frequency response and reliability of the units, should be considered a short term fix...


thanks again -- looks like I may try to fix these and also order the new diaphram/new mounting kit (mine are older style screw mounts -- supposedly the newer pop on style eliminates this issue...) from Bill at Great Plains.....
