I will modify YOUR Broncolor Flash Head to take Briese "single" Flash Tubes. This will allow your Broncolor (line voltage) generator and head to accept any current Briese 800-3200Ws Flash Tube. Your Broncolor head will install (via the integral threads) to the Briese focus tubes making your Broncolor system compatible with all of the Briese Focus Parabolic Umbrellas. Again, this auction is for MODIFICATION of your Broncolor head so it will be compatible with Briese flash tubes and Briese Focus Parabolas. The fact that it is completely Broncolor electronics, generator and flash head, makes it much more reliable than a Briese flash head modified to be powered by a Broncolor generator. *Note: I can modify your Bi-Tube head for $2495.
