| Step Up/Down Transformers - Good or Bad? Consumer grade step-up transformers are usually poor quality and not really transformers but autoformers and have virtually no AC filtering.Industrial grade step-down transformers can, technically, be wired backwards but, although I've never tried... | |
| system synergy "Synergy" has become an abused term, more often reflecting preference and taste than electrical compatabilty. It's actually easier to mix and match with the older gear because there used to be almost a pseudo-standard for impedance, gain and sensi... | |
| Variac vs. Isolation vs. Balanced Transformer? ALL As far as iso vs balanced...http://mysite.verizon.net/vze22yzp/id10.htmlThere are regulated transformers such as Sola (MCR series), Stabiline and Powerware (50Hz) that will correct (95V to 130V) but I doubt you'll want to be in the same room. | |
| I Just Don't Hear It - I wish I did The way I see it... If a tweak or even a component makes an audible difference than something was either wrong in the first place or afterward. If we agree that no component is ideal, then no system is ideal but an optimized system would be less s... | |
| Recommend speakers for a restaurant sound system The only PA system that even reasonably impressed me had TOA speakers. Their mini arrays spread the sound more evenly around a larger room and can be configured in many ways. A Bryston integrated should be enough juice. | |
| What power conditioners can convert 230v to 120v? I've read two similar but different things about using 60Hz transformers on 50Hz. One wrote that the transformer should be derated by 17% to 20% (50/60). The other wrote the input voltage must be 17% lower than the maximum rating.The latter being ... | |
| How did you discover audiogon? Turned left at Greenland. Back when I had green. | |
| What power conditioners can convert 230v to 120v? Try to avoid "converters". They are usually cheaply built autoformer-based. rather than a true transformer. If you do require a step-down transformer, check out used items on Ebay. I just picked up a regulated one for $29 that would have been over... | |
| US only sales WHY??? Declaring a lesser value is fraud and the border agents are more resourceful than most people assume. They have the computers to check Ebay and Audiogon records and often do, as well as contacting the seller. Not only can they fine, they can confi... | |
| cheap high quality power strip You can't have this one... Snagged.http://cgi.ebay.com/SOLA-MCR-1000-POWER-CONDITIONER-FILTER-LINE-AC_W0QQitemZ370193596065QQ | |
| isolation transformers hum Not familiar with that brand and couldn't find info.Most of the better brands are rated for below 50dB, under 5KVA. I've got two (5000VA and 500VA) and can't hear either without a stethoscope. A third should be soon. Hasn't always been the case an... | |
| Size matters Smaller that is It's not how big but how you use it, right? | |
| how many folks have +10kVA trannys before the rig? Albert, if anybody can push the limits of 15KVA, it's you. Gas appliances? | |
| What matters most in speaker design? Resell value and brand recognition to be able to resell locally. ;) | |
| how many folks have +10kVA trannys before the rig? The Mac 501's (each) require 6.6A @120V, 50/60 Hz. |
