Ive used Flash Fix twice in the past two years to repair my aging Novatron heads that suddenly stopped flashing. I used the drop off / pick up service at Dons Camera both times, and the repair turnaround time was less than 10 days. Each time I received a call from the tech with an explanation of the replaced components which had failed, and the price for the repairs. The repaired flash heads work like new. Use this company for your Novatron flash equipment repairs with complete confidence.
