About once a week I get asked “ Do I support the Quantum Flash series like the T2, T4, T4D, T5D's and Trios".  And the second question is, do I rebuild the Turbo 2+2 packs.  The answer is NO and my final answer NO!

I usually get the call after someone got a two hundred to four hundred dollar upgrade or repair bill from the new folks who bought Quantum. I’ d love to help them but. 

•  Simple...my battery packs will not work on them, thats reason enough.
•  They are capacitor driven and capable of 335 volts.  
•  They made their products totally reliant to function on their own ancillary products through the use of specialized cables, lots and lots of electronic components, secret assemblies, no schematics, whiz bang technology, blinking lights and turn signals and very few outside repair facilities so It’s called profit and makes big dollars.  
•  Then they sold out to 
ProMark Brands, in Bartlett, IL and most of their prices went up.  Repairs are expensive.
Many who wind up with one needing overhaul, dump it on eBay because they can’t afford the repair.
•  To power these units you’ll need to get a Quantum Turbo, about $400 to 679.00 new and about the same used if you get a bad used one you thought you stole on eBay that needs repairs.

•  Thats the hidden costs of those things. One will not work without the other and now you have two expensive parts and if pack A gets used up during a wedding, you'll need a spare.  A Trio and two packs is about $2000 and no guarantees after you spend the money it will perform as expected.

•  I do not service any Quantum packs anymore either.  At one time I did. I used to re-battery them, tweaked the comparators and returned them to service.   There are just too many that are getting too old, too many versions, different boards, and some are beyond hope and really need the garbage can.  
•  Once in a while if you are nice I will re-battery a QB-1 or QB-2 but forewarned only with ZYLONS which were the great original factory battery.  No subs and they are not cheap. Today they use less capacity less expensive batteries which fail quick with lowered capacity.  I do it right or don’t do it at all.  B
ut I have made some lithium monsters.

•  Otherwise send the pack to the nice folks who bought Quantum and expect from about one to two hundred dollars for batteries and a new board if it needs one. With new batteries they will calibrate the pack, if the boards are still good and you will be putting them right on top of hot batteries which will kill them again. 




Those black and silver cases were  DCB's, beautiful, expensive and advertised as "the fastest battery pack in the world”.  True but fifty seconds later they became known as the shortest lived pack in the world when they blew the guts out of a bunch of about a 100 just released brand new Canon 580s and when the smoke cleared, that was the end of the DCB company and their product and a bunch of working Canons.  

It also showed a bad flaw in the 580 series one that it didn’t like accelerated packs, overheated and blew.

The sports shooters got blown away because a fellow sports shooter Rob Galbraith touted the program for his freebies.  This batch came to me when no one else wanted to tackle them. They were so hard to take apart we used a drill press and wood blocks to get the old swelled packs out of the cases.  

When we got them apart, we knew we were dead in the water. Couldn’t put anything back in due to swelling and corrosion. I believe these might have been from the vendor at Busch Gardens. The only outfit dumb enough to buy them and he is in my town. Thats 12,000 dollars of no good plus strobe that got blown.   And i could have supplied them for 2000 dollars and they would still be working today, twenty years later.

I get calls all the time because the company was located fifteen miles from me fortunately they died off.   They were dispatched to the aluminum pile, with the  only salvageable parts were the micro switches and  screws.  DCB of Trinity blamed the cable company, Paramount Cable, Bronx NY for putting too strong a capacitor in the cable which was their idea of how to step down 14.4 volts of hot Ni-MH and then accelerate it direct into the flash head capacitor claiming a full power burst in sub second interval.  Canon said, “ Not my problem, unauthorized usage with non Canon parts“   Years later, there  was still a blame game till Paramount sold and DCB bellied up.   Fortunately, the calls have died off and I sold off the aluminum, about a radiators worth at the scrap metal place, nothing else usable. The weird size batteries were useless, if not dead , fit nothing else.


If you buy an original and it’s dead I know of no one in the industry working on them.  If you are so enraptured by the round reflector shade buy one of the clone knockoffs from China so you look good and when it toilets buy another one.  Round shades were great when we had 21/4 square format,  slow ISO’s like Panatomic X, Plus X, and Verichrome and needed the sharp specular light to make them work. 

One guy luckily gets a shot with the round reflector and all the lemmings jump on the bandwagon with their gotta have lists.   Their first job with the harsh light blows out the highlights and trashes it.  I was friends with the Armato brothers on Long Island years ago and some of these strobes now have had five or six owners, mostly Strobists, who get really excited about them. (Makes them look professional, teddy bear photography)

Warning:  Capacitors especially the big dual stage ones in them can be shockingly dangerous (lethal) in the rain.   Again, there are no parts, no boards,  no tech support, most schematics lost,  and the newer equipment with higher clean ISO’s really filled the gap.   Their advantage was for a time period forty years ago with slow based film like Plus -X and VPS etc.   All that has changed in the market with digital. You will need a Quantum HV for the 300 to power it if the cable is right. If not stand back.



422D - 433D SERIES:  These models performed well on the Black Box - No Problems with the 422D-433D - 120J, if they are still alive.  They can be used  either on a stand or on the camera when used in manual mode or/with “ Auto Thyristor Assist" if used on digital bodies.  

Their Low synch rates on voltage made them safe and a much better performer than their failure prone SunPak 383 which was a price promotional model. Cables are available. These work great and easily converted for slaves.  Do not buy a SunPak 383 It was very weak in its design, construction and longevity and as a competitor to the older Vivitars it sucked.  Fortunately it was very short lived and few or non around.

But many SunPAK’s can be found in pawn shops, the good part is you can steal them.  Bring batteries, and test them, Use the MG2 Cable.  look for corrosion.  Developed by one of the oldest flash importers, the SunPaks date back to 1963 when they were established in Saitama, Japan.  They were really popular in the analog generation.  Offer five dollars telling the guy they only work on film and film is dead.  He won’t know.  Check the battery compartment, usually thats killer one since they left the batteries in it. No I will not clean it for you. Cheaper to buy a Yong-Nuo or Neewer.

The 120J SERIES:  Is another fairly good performer, designed, styled after or copied from the Quantum “ “ series. Quantum's prices scared people so SunPak took the 400 series, stepped it to bare bulb and added a domed hood.  They are fine on stands and brackets and produce a specular light. The diffuser or modern frosted coffee can lid  elastic cord or/and velcro is the better way to go since it’s not bigger than the reflector.  Still usable till they fade out.

611-622 SERIES:  Another great legacy performer (the 611, shown) that did well on the Black Box and I pushed this unit because of its power and reliability during it’s era.  A good one today will out perform almost any strobe made with the exception of the METZ 776.   (The 611 is sold)

Problem was, it’s bigger than most cameras, heavier and very complex.  Next problem is they are basically non-repairable. Unfortunately, they made the obituary list, no longer sold other than a few lying around, few independents like me saved parts for them and no one in their right mind would work on them, so off to the trash heap.   Recently I took one apart for grins and surprise it had four (4) motherboards and more connections than an attorney for the mafia. No wonder no-one worked on them.

CAUTION:  There were a few of the 622s for sale going around and even some bases, thats the huge handle part which can be found but no heads, so don’t get trapped buying one without a working head.  Again they are not repairable, very complex to take apart with about five miles of wire and boards, not fun to work on,  so don’t ask me.  

522-544-555 SERIES: Recently I started getting requests for the 522 series. Now these units used a six battery setup in the head meaning a demand for 7.2 voltage and that allows me certain liberties in what I manufacture.  

I will be offering the Black Box with an appropriate voltage in NiMH with capacity exceeding commonly used AA and NiMH AA batteries.  Actually we are configuring 3800 NiMH 186 cells into two columns with a capacity of 7600 Milliamps which can exceed almost any other configuration out there.

WARNING:   An option I have seen might be a pack constructed from large Lithium-Ion being aware of the airlines reluctance to allow on board.   I am quite familiar with this since I wrote the article and I do not work in Lithium,  a lot more dangerous than you think.  
Just recently I got a call about a battery store who  found out what happens when they tried to solder Lithium.  You have to weld (we don’t solder packs, it drops them 20%) Lithium carefully.  It dropped the fire department on them, the fire was small but the fire department decided to inspect them,  and that caused severe financial damage     .
