** Hi,

do any people here regularly attempt to fix these things or just replace
them ?

I get a lot of dead and bad sounding units - used to be only very old ones
but now most are in new looking condition.

Accutronics ( now Accutronics / Belton) have made a couple of major blunders
in recent years - first they added little white plugs to the drive and
pickup coils and then they added a foam plastic impact pad under the
springs.

The white plugs were a disaster since they impacted at the ends of the metal
box and caused the hair fine wire on the pick up coils to break. The foam
plastic pad was a time bomb - eventually it perished and turned into fine,
sticky particles that coated the springs and damped the torsional vibrations
so much there was no more reverb.

I have found good fixes for the white plug ones and ones with broken feed
wires and even ones that have the tiny magnets resting in contact with the
laminations of the drive and pickup coils.

Cleaning springs coated with sticky foam particles with solvent ( even
Acetone ) has not proved a complete success - the resulting sound is still
sub standard.

Guitarists love these things but I wish they would treat them with more care
as many I see have been subjected to massive impacts - over and over. I know
this for sure when I see lose and missing steel pins that are intended to
limit movement of the sub frame !!

The fix or this last one is to drill out the holes and fit 4x30mm size bolts
in place.

Bloody heck !!

I have a box of around 12 of these in the boot of my car, which is going to
the local dump this morning.
They all have O/C coils.

I've kept them over the last 5 years or so, in the vain hope I will get
round to mending them, but have now decided enough is enough and they are
going, along with another ten tons of broken power amps, powered speakers,
all kinds of ****e that I am never going to get round to fixing, or I would
have done it long ago.

Its very cathartic to do this every so often I find, and it means I can now
see a bit more floor in the workshop.
