I have a Maz 38 Sr and a Carmen Ghia both early versions with no voltage rating on the back but are UK amps are they 230 volt or 240 volt and what do people think about this subject please, think current UK voltage nominal is about 245 volts the last time I measured it with a Fluke meter !

Depending on the age of your amps that voltage value may very. Early Z Amps were shipped to Europe with a 230V 50 hz input power Transformer. As wall voltage increased I upped the Power transformer rating to 240V 50 hz. Currant production export amps are all 240V 50 hz , except Japan units witch are 100V .

Z Ok, well I am impressed, thanks i think both amps are around about 15 years + old so I guess probs 230 volt is there any way to tell and what is the trade of at running at 240 volts + . Should I use a variac on them such as the Amp rx ?

The Ghia with a 5Y3 and any 4 EL 84 amp will be fine , but a variac set to 230V will increase tube life. Too bad the Brown Box isn't set up for 240V as that would be best solution, maybe they will some day.

Z OK, so both amps start with a serial number O. which makes them 2004 so wondering which tranny 230v or 240v thanks for any insight.

Z Dr. Z, I have a 2015 Z-Lux I bought out here in Switzerland, through a dealer in Germany a couple of years ago. Do you know if this has 240v 50hz? Thanks, Bob

Good to hear! Thanks, Dr Z!
I love this amp. I'm playing with a country band now and have a gig at a country music festival next weekend here in Switzerland, at Interloken. The Z-Lux sounds amazing, especially for this style.

I have just purchased the EuroVolt, as I live in Southern Spain; we’ve been using a Furman PL PLUS CE power conditioner that we’ll keep using, but here my question arises: Do I plug the EuroVolt in the wall socket or in the Furman? Thanks a lot in advance, and tons of tone!

Hi Andy. I'm no expert, but I bet you could plug either unit into the wall first and it wouldn't damage the equipment. The order might have an effect on the tone or feel of the amp though. Have you noticed a change in the way the amp feels with the EuroVolt ? Cheers

Out of interest what would the effect of running an amp designed for 240 at 248v be? Would it result in more noise/hum at idle? BR Ben

My unprofessional opinion, there are a whole bunch of factors that could effect the idle buzz, but yeah , I think you could start to hear a difference if you bumped the voltage up by 8 volts. 1 or 2 volts, maybe not. But I think 8 V could be enough to increase the buzz.
