I have a nice Sony ta f700Es integrated amp on its way from Germany. Only problem is that it is a 220v model. It doesnt have any obvious voltage input selector adjustment showing on the rear pics. I'm hoping it has an internal voltage selector but I wont know til it comes and I open it up. I dont really want to go down the step up / down route. I've been told a bucking transformer is the way to go. Just want something simple, non bulky, non noisy. Would appreciate some advise re: options / best route.

Do you know what your mains is delivering? They might be perfectly matched - you never know!

Rob, I was going to import one of the big Sony amps myself last year and I bought a little gadget from Maplins to test the mains voltage and it did the job no probs... I can send it to you next week to use if u like when I'm back in London - it's just sitting in a drawer at the moment...

Ding-Dong! - It's Robbiegong!
If you Google "Sony TAS 700 ES Manual" you'll get a direct pdf download from audio-labo-vallespir.org/. It's partly listed as sony/taf44… which it's also known as (
TAF 444ESX). Looking at it it was for use on 120/220/240v and appears to have a voltage selector board. So it seems you will be able to set it for 240v. James appears to be a Sony fan so will probably say for sure.

Follow the advice above and you'll be ok. If you can only select 220V, such components usually have enough margin built into them that they will work fine provided your AC isn't much more than 240V. My house mains is at around 250V most of the time but my regenerator creates 240V regulated output so that's another way you can get what you need.

The panel is on page 19 of the pdf file and is shown as page 21.

Good to see you posting here  Yes, can only echo what has been said above... Measure your mains first, if its below 240v it will be fine without any type of external transformer IME. It may have a voltage adjustment PCB internally but these Japanese amps were usually produced with different transformer configurations for different regions so there will be the Jap model, the US model, the EU model & a UK/AUS model all with different input voltage & no option to change it... Occasionally they would also produce a "world model" with a voltage selector, these were sold primarily to Yank military personel serving abroad (was a massive market back in the day). ... It all depends which one you've got, as its coming from Germany I would presume it not to have any internal adjustment but you could get lucky. Once you have it post up a picture of the silver label on the rear panel & I'll be able to tell you for sure which model it is. |

Hi guys, MartinT, Jules, ChrisB, James, Nice to touch base with you guys again. Heres a link to the exact item I'm waiting to receive, got lucky with a decent best offer. Fortunately I had someone from Germany do the honours on my behalf. Here's a link to the exact item James, if you scroll down you'll see a close up of the silver sticker on the rear panel. Something tells me I'd be mighty lucky to get one with the internal voltage adjustment option but you never know. www.ebay.de/itm/Sony-TA-F-700...342&rmvSB=true Martin, I'll defo let you know what it sounds like once it's here and 'safely' up and running. I've read a lot of good things about the big ES's, been trying to bag one for a while. Jules, How you doing ? I'll pm you regarding your kind offer. BTW, you're to blame for rekindling my interest in the Sony ES's .... All the best Rob |

Piccy's not working, Rob. You'd need to point to the public listing, not anything inside your account.

I had a German TA-F770ES and it had no voltage selector, nor multiple taps on the mains transformer, so it was fixed at 220v. The 700 is likely to be similar.

Got the pics, thanks. I still wouldn't worry provided your mains is not running over 250V, and even if it is you can keep an eye on it, Sony build a lot of tolerance into their designs as do all the Japanese vendors. Not necessarily so the Chinese ones.

That appears to be the 220v non adjustable version Rob. Use Jules' tester to check what your mains is running at, unless overly high (245v+) fit and forget.
