CLA -Clean Lube and Adjust
Nick - do you mean:
get any loose contatcs replaced/tightened,
remove and replace burned contacts,
make sure all internal and exterlal hardware are in place and snuggly tight
check for swollen//leaking capacitors
check that the charge being delivered is up to snuff
check that the charging voltage isn' too high, and concequiently prematurely aging the capacitors dielectric
check that they recycle within the OEM's specfoed time?
I'm not aware of any shop set up to do all such repairs, although there must be someone in NYC or LA that puts dead brownline/blackline/elinchrome
etc. untis back into a usable state. Most rental shops of continous lighting (ala White here in Toronto) have shops that fix what is dead, i am not aware of anyone who rents enough to rebuild - perhaps Headshots would know.
