Okay so after long deliberation i have bought the Orange TH30...and I LOVE IT! Amazing amp. Anyway I hear you should usually replace the stock tubes in all new amps because they generally suck. Firstly do I need to change them? Is this one of those rare amps that comes with good tubes? If not then which tubes from this list should I get?

Sorry for the massive list.

Thanks

Play it and see what you think. From your description, it's an amazing amp. If you like the tones you're getting, why replace the tubes? I've never replaced the tubes in my amps until they either prematurely failed or were ready for replacement. Let your ears tell you what to do.

About the only useful ones are the 12AX7 Matsushitas. Not sure what the other 12AX7's they have listed are. They could be anything really.

A set of JJ's will make a pretty big difference and save you money. There was a time when Orange used good tubes, sadly that is no longer the case.

Steve, I spend quite a bit of time going through my tubes to find the best sound for each amp. I don't just change them because they fail. Well, except for the JCM900, it gets whatever happens to be laying around.

I've thought about doing that. I have enough spares lying around that it would be easy, but I tend to get to a point where I have an amp totally quiet and its tone is good, so I hate to monkey with it. My Mesa Lonestar used to be quite noisy with the stock Mesa 6L6s in it. It improved dramatically with a quad of GT 6V6s. I could cite some other examples, but you get the idea.

I put sovteks in the power section of my th30 combo and the results are ridiculous.

If Sovteks improved it the tubes in it must have been total shite. You gotta dig pretty deep to find something worse than a Sovtek - like the crappy OEM tubes Shuguang make. If you think the Sovteks made it sound good, SED =C= or JJ would make you mess yourself.

If possible can you recommend a good webstore for tubes? I have a new TH30 that just arrived and didn't really put much thought into the tubes. I think it's made in China so must have some sort of Chinese tubes I guess.
Also I've heard people say Russian tubes were some of the best. Maybe that refers to Svetlana not Sovtek?

Thanks

There are two types of Svetlana. Ones made by New Sensor (the Sovtek guys) and ones that are made in the actual old Svetlana factory which are called SED =C=. New Sensor bought the name.
The ones labelled Svetlana are nothing special, the SED ones are the best modern tube on the market.

Basically, if you can afford SED, buy SED. If you can't, buy JJ. JJ are better value for money.

There are a few good places to buy tubes. Tubedepot.com and dougstubes.com are two good ones.

Whoa the SED is sort of expensive. I thought JJ was a model not a manufacturer. haha I never checked into it that much. Only replaced tubes 2x. Once for a Mesa .50 which got..Mesa tubes and
once for a MIG 100H which got..Sovtek tubes.

Thanks for the info

Funny that you should mention a Mig. SED tubes were what they put in Mig fighter jets They can handle up to 3g of force. They're expensive but they are damn good.

As Cath mentioned, Tube Depot is a good choice. I've used them in the past and will use them again in the future. SED =C= are good tubes. I put a 6L6 pair in my ol' Peavey VK112 and it cleaned up the hum on the output. Also had to replace a noisy preamp tube on that amp. I think I've ordered from Doug's, too. The only place I would avoid is eBay.

Someone should do a comprehensive tube thread. I checked youtube but not really any comparisons there.
