I'm building a new power supply for a game that's going to drive a K4600 and I need a transformer.

Who do you recommend?

Thanks for the help!
 
If all you need is an isolation transformer for the monitor, you can post in the want to buy section or buy one for under 20 bucks from the arcade boneyard
 
Twisted Quarter or Suzo Happ. Happ's minimum order was reduced to $50 recently I read.
 
I second Twisted Quarter.

Yeah, good place but their 1:1 ISO transformer I bought from them is more like 122 in, 135 out. Not a great ratio.

Maybe they're not all like that; I dunno.

I'm having the same issue. I just need a decent but cheaper 1:1 isolation transformer but shipping is the killer for me.
I really like twisted quarter but shipping is almost 3/4 the cost of the transformer. I do order from them if I have a larger order.
I tried Arcade Boneyard and they had a good used one for around $16, but shipping was more than the transformer.
Other than that I can't find any others at a reasonable price anywhere else including eBay. I think Bob Roberts had them but he's on hiatus.

Suggestions? Anyone got one they want to sell and ship at a reasonable price?

Shipping is what it is. Isos are heavy and I don't think there is a small flat rate box that one fits in. Maybe email twisted quarter before you order one?

I understand and I'm not bashing them for it for sure. They have a bottom line and they aren't a charity. I also have ordered from twisted quarter and was very happy.
My thinking is that an isolation transformer would fit in a USPS flat rate box and go for around $6-7. I could be wrong but still I am going to shop around a bit more. I'm not in a big hurry for it.
I'll take your advice and email TQ to see if that is a firm shipping quote on the website unless I find a different source right away.

Oh, I didn't think you were bashing them at all. It's just shipping costs suck so bad right now. I swear USPS knows exactly what can fit in those damn flat rate boxes!

I really added the "not bashing" part in case TQ or Boneyard happened across the thread. It's easy to misconstrue things (especially with my writing skills) and I wanted to be clear on my post. Thanks for the advice and you are about right on those USPS boxes! :)
 
I've bought the ISO from Twisted Quarter, plus caps and other small items before and I'm about 90% sure it raised my shipping no more than $10-$15.

I'd consider them to be $30 cost.

The one I bought worked great - correct voltage out with load etc.
 
Quick question... I seen isolation transformers rated in VA. How much power do I need to drive a monitor? I would hate to get one and it not have enough oomph.
 

I checked out the link and besides that one I'm finding them all over eBay now, some with free shipping. How in the world did I miss all those? My "Search-Fu" must have been really pitiful that day. I'll look at them all when I get home and post if I buy one. Thanks!

I've never seen one that needed more than 120v for a monitor. But I mostly dealt with the more popular 80's monitors (Electrohome G07; WG 4900 etc.) and 90's monitors (K7000 etc)

I griped to them about the shipping cost of their ISO and didn't realize just how ridiculously heavy their ISO was until I received it. Dang, it's absurdly heavy for its size.

I think I had TQ ship it USPS and that helped. I've also discovered that TQ's shipping calculator often errs on the high side and actual shipping wasn't as bad as what it estimated.

I just wish it really was a 1:1 ISO. Instead it's more like 1:1.1.
 
va is volt amps and a function there of (math = divide )
here is a fast guide for what u are doing
copy and use as ref. material

When purchasing a power source such as an uninterruptible power supply ( UPS ) for use with electronic equipment (including computers, monitors, and other peripherals), be sure the VA specifications for the equipment are used when determining the minimum ratings for the power supply. The VA figure is nominally 1.67 times (167 percent of) the power consumption in watts. Alternatively, you can multiply the VA rating of the power supply by 0.6 (60 percent) to get a good idea of its power-delivering capability in watts.

so it is to deal with watts
but u have to multiply the divide valuue (va) and then multiply the load.
