A good range of light and mood David. The beams in No.1 get my high score by a tad.

Best regards

A good set Chris. As comments above, the last image stands out. I had the unenviable situation of being at the receiving end of two Iranian F4's in Basrah.

In low, hard & fast and they have actually gone before the ordnance hits.

Vic, when you put new battery's on the 400's, could you hear the oscillator whining? The most common cause of old dead flash guns is the capacitor but normally you may hear the oscillator working as it tries to charge the capacitor. Since you have used the TR power pack, it generates the full voltage required to the gun without the gun needing to use the internal oscillator and if the capacitor is usable, the ready light should illuminate.

There's a company in London that might be able to help link. Downside is pricing. Most of the repair companies will be wanting around sixty pounds or so.

It's horses for courses John. I've done a few flash guns over the years and not been zapped. You are right about the shock hazard though and the job should only be done by competent technicians or some one who works in the field of electronics. I would not expect Vic to attempt the job, no disrespect to him.

The capacitor can be safely discharged with a 1M ohm 1/4W resistor on fly leads.

Vic, the electrolytic capacitor in the flashgun is the problem area. With age, they dry out which in simple terms means they stop being a capacitor. Just as with old HiFi amps, the capacitors are replaced with modern equivalents, much better, smaller and more reliable. This does mean that the flashgun needs opening so not something that most will attempt.

Any slight recovery will be just that.

Capacitor replacement is a common thing, just make sure that the correct operating voltage for the capacitor is known. Easy to do when the original is removed as the capacity and voltage will be on the component.
