LIGHTING EQUIPMENT REPAIRS
Thu, 8 Sept 2005, 01:00 pmIf it isn't politically incorrect to ask, does anyone know of a reliable firm to repair things like dimmer boxes and lighting desks. We have had sad experiences with some of the larger firms and this is a pain when you are freighting things back and forth from a counrty town.
We are having trouble with a Jands Roadpak analogue dimmer box. Is this the sort of thing a competent licenced electrician should be able to fix?

Most electricians would not have come across theatre dimmer racks so it would not be their forte.
You do need an electrical license to work on any mains equipment, I have an open restricted electrical license to allow me to work on 440 volts three phase equipment.
Here is a copy of one of my posts on the ALIA website with a link to a tech bulleting that you need to read:
"For those that are not aware of the failure of dimmer mains bypass capacitors used for inteference suppression, Jands have a Technical Bulletin Sheet TNJLT094 located on their web tech support area http://www.jands.com.au/download.nsf/getfile/E8AB225AE7424D2DCA256EFD001D0ED4/$File/tbjlt094.pdf that is also applicable to other brands of dimmer racks.
Usually if it is left untill after the capacitors have caught fire, the pcb is blackened and quite often not an economical repair.

I subcontract to several Perth lighting companies including All Things Theatre, Pro design Lighting and Illusion Lighting so you can go through them if you want.
Being an ex Strand tech, I have a soft spot for JTM dimmers and maintain several venues, being fortunate enough to have obtained workshop manual with circuits.
There are other techs that look after the older gear, one works as a part time lecturer at WAAPA.
Hope that helps
