my Orange AD200B Unofficial Manual

    ...for those interested in everything about this amplifier - tubes, biasing, connecting different speakers, technical info, etc. - Hope you like it -

    As you may know, this amplifier does not come with ANY manual, also, there's no info on biasing... and if you use web-bias-calculators you'll not get right voltage from that (about 2x higher)! Remember! So here's one. Excuse my bad English.

    If you have any adds, we can discuss it here and put some corrections into this one :)

    I am surprised no-one has replied to this so I will - thanks very much Boroman. You have obviously spent a lot of ime on this and provided a great service. I have been looking at buying an AD200B and this is a considerable help as I contemplate a decision. Either way I have downloaded it for future reference. The only thing that bothers me is whether or not it has sufficient "loud clean" for me.
  3. Good lad!

    You, my friend, are a legend!

    Nice one!.

  4. CONGRATS!! AN interesting read & I dont even HAVE a AD200- I'd LIKE one.....

    Well done!!!!

    Hey, Thanks!

    Tim, it isn't the cleanest amp I've played ;) Especially if you have a high-output bass. I've tried it with vintage precision basses and it sounds clean to good practice/small gig volume, it stays a little "Creamy" when pushed hard and get a nasty overdrive when it's more than 3/4 volume. I LOVE that cream tones and little dirt when i hit my bass hard - this amp does great job with it.

    I tried it with passive vintage Telecaster Bass (yes, this one with humbucker) and it distorts very, very early, even connected to Active input.

    I put JJ KT88's in my AD200, but I didn't heard more headroom or "more clean watts". It's just more creamy than 6550's which were rather "dirty" than smooth.

    PS: I haven't played it on gig on more than half voume and half gain. And it was painful LOUD then, with Ampeg 8x10.

    Are you completely sure about what you say of the equalizer? Passive does not ALWAYS mean subtractive, as far as I'm concerned.

    I've been told that EQ in this amplifier works like old Fenders (don't remember which ones, a Twin? a Super Reverb?) which had passive-substractive EQ's.

    The only detail I have doubts about is the eq. I'm sure I've read somewhere reliable that the flat settings for bass, mid and treble are about 8, 12 and 8 o'clock, respectively. Can anyone confirm?

    There's a post on TB somewhere about the 'flat' EQ on the AD200B. It's passive, but it's not fully subtractive.

    Edit: I recall the 'flat' setting on the bass knob being 3/4

    This is it!
    quote=xsubs;6522899]I had posted this before on another Orange thread, but since it came up again...
    The info is from Will at Orange, regarding the eq position for "flat". It's a bit surprising... cut from his email to me:

    Bass - 3/4 up

    Mid - 1/2 up

    Treble - 1/4 up

    Sorry to play the necromancy card, but is this information still available anywhere? Link is broken.

  18. Lomo seems to have missed you, maybe PM him.
