I think alot of us here like JJ power tubes. I havnt had much experience with any other brand of el84, but thetubestore.com has some good descriptions of different tube brands in thier reviews. I think that the AD30 is "self biasing" so you can plug and play. I'm sure if I'm wrong someone will chime in.

they're different. not necessarily better/worse. this is what Jon @ thetubestore.com says about'em:
Jon wrote:Electro Harmonix EL84-EH - For most applications this is a good bet. The sound of these tubes is very smooth when biased correctly. Tonally, it’s hard to go wrong. They are pleasant to listen to and have the creamy overdrive most people look for in an EL84. They have a nice chime but it’s not overbearing. It looks a lot like the standard Sovtek but a closer inspection will reveal differences. The plate looks a bit more polished with a different coating and internally they feature precisely wrapped grid wires with a bright metal shine. The only problem with this tube is that like the Sovtek and TAD product, they are tubby. The fattest one I measured was .886 inches thick against the G.E. maximum width spec of .875 inches. For most purchasers this will not be an issue. If you have an amp that requires the tube to pass through a hole in the chassis before the pins seat in the socket you should measure the diameter of that hole. If you’re still unsure, the JJ EL84 is the closest in dimensional specs to NOS measurements and the G.E. standards for the 6BQ5.
i've not personally tried'em, but i've found jon's reviews really useful and pretty reliable in terms of tone.

Watford Valves Harma Retros are the nicest non-NOS tubes I've tried in my AD30.

I second this. JJs seem a bit overbearing somehow. Watford Valves are very good and quick. They are based in the UK though...

I wouldn't buy tubes from Guitar Center, personally. I'd use the Tube Store or Eurotubes online. Both places are well known for their customer service (unlike Guitar Center), and I know that if you call Eurotubes and ask them this type of question, they'll give you good advice. :)

The AD30 is cathode biased, which (sort of) means it is "self biasing." So yes, just buy your new power tubes and put them in, just make sure you are buying matched power tubes.

Probably 12AX7s, but feel free to look inside your amp to find out. You could also use 12AT7s or 12AU7s for less gain/cleaner tone/lower volume.

Hello Guys!
Just got an Orange AD-30 Single Channel
It came with JJs
I'd like to install the stock tubes, I saw that in early 2000s Orange uses Ei as EL84 power tubes and Sovtek GZ34,
Can Somebody help me to find which were the stock preamp tubes?

Many Thanks

You'll find that JJ's are what they use.
