I have a Pentax power pack model TR2 which is originally designed for the AF500 Flash. It will run the AF540 FGZ just fine as well. I used it for more than 500 flashes (2 weddings) with the 540. The difference is the voltage output. The TR2 for the 500 was designed to put out a max of 340 volts and the TR 3 for the 540 is designed for a max output to 315 volts. I`m selling it because I`ll be using battery operated portable studio strobes from now on.
new this was $149.99 in the USA ++. I`m looking for
SOLD incl Paypal $10.00 to ship in N America and about $15 to worldwide.
