FS Egret 2/Windy 2/NNC/Q25 (Repair refund)

For Sale
There are actually two different types of isolation transformers that I know of. The ones you find today all link neutral and ground at the second primary side for EMI/noise cancelling.

If you're working on a live monitor you do not want that and you need to modify it into a technicians isolation transformer by severing the neutral/ground connection on the 2nd primary. Failure to do so can blow up dat oscilloscope or you if you touch even one point wrong.

 
For you those out there that have multiple Candy cabs and a 110 100 step down transformer, do you guys plug an AC strip/surge protector/or whatever you call those things into the 110 100 step down transformer to run all your Candy cabs? Or do you have one step down transformer for each of your cabs?

Both works depending on the Wattage of your step down, don’t run 4 cabs of a 300w step down ;)

Personally I have a 750w Airlink which has dual outputs for 2 cabs, but before I used a power strip on 1 500w step down for 2 cabs (which might have been on the edge...)
 
Cool. I'll check what my 110 100 step down can handle. Would not be often that more than one cab is on at a time.

Someone know in Japan do they run Egret 2 @100v on the cab PSU yes? Assuming not using ms9 off mains then which spec for 120v +- 10% variance AC on SMPS input? ?(

I use a couple of these, does the stepdown, surge protection, battery backup, etc. Running these for a couple of years now, never an issue.

I use 2 of these, with 2 cabs plugged into each with small 2 plug power strips.

I used to use those and they work great in conjunction with surge protectors.

But for my needs.....we always have power issues here. Coastal life with overhead powerlines, etc.. during winter, so can always expect power lines to be down 1 or 2 times, or power outages a few times etc.. During summer brownouts, etc. expected. Everyone in the neighborhood is running huge central AC units, pool pumps, pool heaters, etc.. so you always get those dips in voltage levels, etc...
 
This is a long and winding thread but I seem to remember some discussion of possibly converting these before shipment. I guess that didn’t happen?

They have been converted back to stock/OEM. But stock/OEM means 100v AC as that is the standard in Japan. You can plug these 100v AC cabs into US 120v AC outlets and they'll run, at least for a while. But it is recommended for the life of these cabs to step down to 100v. Lots of horror stories out there of Candy cabs dying and it has been often attributed to running them off of 120v AC. Read up on it.

I feel for personal home use a step down isn’t really necessary for most candies. I’ve been running all my cabinets without a step down just fine with no issues.

However running all day for commercial use, you will most likely need one.
 
I have owned my Egret for about 7 years and never used a stepdown. Never had any problems with it either, and for 5 of those years it was my only cabinet and put through the works.
 
Ahh yes, this debate... As usual no one brings AC to DC theory into it. If you wanna use a Step-Down then by all means do it if you want that safeguard, extra peace of mind.

I have encountered 2 JP Electronics that have failed on US Voltage. Both results were completely different as they were completely different circuit types.

1.) 100V rated JP Unregulated supply Hairdryer. These have no regulation at all, the heating elements are designed to work on 100v. Elements melted after 3yrs of use.
2.) Astro City on 120v for over 10yrs on a non-surge protected line. Blew all the regulators (stopped working after storm which resulted in a power outage), classic surge killed it. Replaced and worked again.

- Unless you have an older 80s or so JP cab or an oddball cab that is running unregulated power. > All our PSUs are regulated and/or regulated and switched. All Candy cab monitors have Regulated Supplies on the chassis.

That extra 15-25v is gonna be dissipated off the Power Supply circuits and Voltage Regs. So if anything, you are more sensitive to surges, as your tolerances are lower.

TLDR: Proper Surge Protection is the most important over everything here ppl have recommended. A Stepdown or Up without having proper surge protection used in addition is 100% useless. Don't be cheap or think cause its never happened that it never will.

@acblunden2, 110v? Guess you mean 100v? :)

Yeah man, I went back and made edits :P

$40 for a step down convertor. If all that buys is peace of mind, I'll settle for it.

I can tell you that lots of arcade schwag comes up for sale in my area. But hardly any Candy cabs. Whenever a Candy cab comes up for sale, it is dead. When I ask the seller if they used a step down, they respond with "what's a step down?". I've now fixed Nanao chassis on 3 dead Candy cab pick-ups between me and some local friends. I can tell you that cost fixed shipped from PnL is about $100. These 3 cabs now run all with step downs and none have needed further repair.


Not sure if there is a correlation. But even if the risk margin is thin, what is being wagered is a $40 step down convertor.

And lots more info.

The PSU in the Vewlix F and AWSD hate not being on stepdowns, both are not 80s cabs. You can even watch the red LED on the PSU pulsate when not on one.

Lots of candies do play nicely with US voltages, but there are as many that don't, and they're not all ancient ones.

I don't have any issue plugging the City or Aero Table straight into the surge protector, but the Vewlix (when using the PSU) and Egret 3 act super wonky. Maybe just blame Wei-ya for cruddy power supplies?I'm not sure, but it's definitely a necessity and not a choice on some cabs.
 
Having a stepdown with the Vewlix JVS PSU is mandatory. And yes people, please use a quality surge protector, not the dollar store ones.
