Ahhh you're the one who got it, I had messaged the same seller but apparently a day after you... Enjoy!

It's 230v though, you in NY? This one sadly doesn't have 120v support and thanks

Contact James he is the US Authorized Repair location for Riviera. He may could change it to 120 for you.

I was going to internally convert it. Can also just use a $150 step up transformer.

I wouldn't be buying a 10k amp and risking a hum. You could also have complicated fuse issues from what I've read on the topic, and they generally seem like a huge PITA.
Unless you really really know what you're doing unlike me

But I only looked into them in a minor way when I had a chance at a US AIC-10. I decided it wasn't worth it in the end.

Yeah the fuse issue would have to be addressed for sure IMO. Notwithstanding the internal fuses, even the Mains input has different fuses for 230v and 115v.

What a great pic. Can you talk about some of the tubes in more detail. Never seen the hivac mentioned. Those are expensive lol

If you mean the Hivac in Ebay, that one is beyond expensive! I was lucky to find one way below the Ebay price from a seller in the UK. Their page doesn't list any more available, but happy to share the link over DM if anyone's interested.

I'll start by saying that I mostly listen to metal. So take all of my below comments with a grain of salt if you don't listen to metal/rock. I'm also still going through brain burn-in, so things might change. I'll try to post an update in a couple of weeks.

The Hivac and the Mullard CV491 are my top 2 tubes right now. They both have a very raw, but non-fatiguing sound. Most metal albums are poorly recorded. So non-fatiguing, warmer yet detailed sound is what I'm after. Overall, the Mullard is probably a better all-rounder compared to Hivac. I'd say it's more musical than the Hivac, but the Hivac impresses more when you have a better than average recording.

The Valvo is also great, maybe a tad worse resolution compared to the above 2. The Mullard 10M is great for vocals.

I have to put the M8136 in a special bucket. I agree with everyone else in the thread, it's probably the best value tube for the AIC10. I'm sure when I spend more time with it, I'll rate it even higher.

The G73-Rs are good, but maybe because of the genres I listen to, I tend to roll the the other tubes more for now.

La Radiotechnique and RCA clear tops are in a tier below compared to other tubes, but they're still enjoyable.

Finally the Holy Grail of Holy Grails has landed!

I use transformers for my Japanese amps that are 100V. No hum. Great sound. Easy. Cheap.

 

[Chronos]

I have a 230v and I’m in the US. I bought a step up Transformer, in fact Riviera advised I try it first rather than shipping back to Italy to change it. I bought a reputable brand made in the US, I have no hum, no issues, and is silent.

What transformer did you buy? All the AIC10s I've seen in the classifieds lately have been 230v.
