For Aussies

[theophile]

I took my 808-8As to Lorantz Audio Services for a re-mag( Lorantz is similar to GPA in that when the Rola loudspeaker company came to an end here, its chief designer acquired the tooling for manufacturing loudspeakers). Located in Dandenong, Victoria.

I removed the rear covers, loading caps and diaphragms - Lorantz would do this anyway.

Lorantz will get back to me with the re-mag field strength measurements prior to any decision to ship the drivers.

Stay tuned.

mah,
Thanks for that.I got the details for a group in Melbourne who advertised remagging.I suspected that they were sending the items to someone else as opposed to doing it on the premises,so I didn't proceed.

My guess is that Lorantz is who they would have been sending it to.

I needed a GPA 604 serviced and they put me onto CPC Productions in Brisbane.

They did a good job for sure.

Excuse me if I'm not correct,but CPC don't perform the remag,they send the component to Melbourne somewhere.

I fully suspect that they all go to the same place.

Murray (CPC) actually sends them to Etone in Sydney if remagging is needed.
He's a top operator.....he supplied me with some 902's & they're just great.

Re CPC...probably so...I was just needing the cones re-done.

Good to know about the Etone supplier.....thanks.

I checked out the Etone website. They offer magnet repair and will repair CD diaphragms in some cases.

808 remag results report from Lorantz Audio Services:

"Unit# ...Flux before(Gauss) ................Flux after(Gauss)

#1 ...12200/13000/14000/13500.....14000/15000/16000/15500

#2 ...16500/14500/14000/16000 ....17000/14500/14000/16000

The four readings are from four measurements made at 90 degree spacing. We tried both impulse and DC magnetizers-both produced the same results."


Altec give 15250 Gauss as the nominal flux density. Unit #1 average is 15140. Unit #2 average is 15375. A good result, I would say.
