Re: [gsp-2101] Recommend me a great tube power amp.

2003-04-08 by Sean Roberts

Well I grabbed that Marshall 9005.
Ended up paying $260 CAD which is about $170 US so for the price, I couldn't go wrong.
I've seen a few up on ebay for 400-500 US.
It's not bad, not great but better than the solid state (Valvestate) I have.
Here's which Marshall it is.
It's an older one (1990) not the gold ones.

Couple of questions.
There's a low-hi output switch on the back that doesn't seem to do anything.
Do I have to have it set at a certain ohm for this to work??
It's set at 4 ohms right now.
Also If I want to bridge the 2 how do I do that?
There's 2 speaker outs for each side.
Ch A/mono input & link out jack
input & link out on ch B.
Would I plug into Ch A then plug a short chord into ch A link out then into ch B input??

Onto tubes....
I'd like to re-tube this power amp.
They're the EL34 tubes & 12AX7s.
Does it make a big difference to get matched power tubes??
Are Groove tubes "THAT" much better for power?
Any recommendations on tubes?
What about the 12AX7s?
* * STUPID QUESTION ALERT * *
Why are there preamp tubes in my power amp?
(Sorry)
Again, matched pair worth the extra dough in a power amp?

Cheers
Sean

  I have a similar amp, a Mesa Strategy 400 Stereo. I agree with you that I’ll never need another amp; Mesa’s are built like tanks. Mine has 4 12AX&’s 4 EL34’s and 8 6L6’s. I bought mine because a friend of mine had one and I liked it and I had bad experiences with Marshall as far as reliability (many failures, sometimes at gigs). This one has been running fine for almost 15 years and I bought it used. It weighs as much as a boat anchor though. - Mark

  I use a Mesa-Boogie Simul-Class 295.  They are no longer in production, and nothing has come close to this baby since.  It is a tank?I don’t have a clue how I could put a dent in it…and it has the sweetest, warmest, fattest tone I have ever encountered in a dedicated power amp.  Has both 8 & 4 ohm outputs on each side, can be driven stereo at 95 watts per side or bridged mono.  Has 2 EL34’s per side, and 2 6L6’s per side; can switch each channel from just the EL34’s (Class A mode) or all tubes at once (Simul-Class) for stage volume.  In my apartment, on the Class A mode, with the gains set at 1/10, you can hear my amp from space?I cannot imagine what kind of nuclear testing site would be required to run this thing wide-open.  

   

  Look for a used one of these babies on e-bay…that’s where I got mine.  I’ll never need another power amp.

  Thanks Greg

  Lots of good pointers!

  I've also considered getting a small tube amp (not just a power rack)

  so I'll look into the DSL201!

   

  Cheers

    I'm using a Marshall DSL201.  It's a 1x12 combo, all tube (12ax7s and
    EL84s).  It is perfect for my gigs (small to mid size, we do classic rock,
    reggae, Steely Dan, etc., very wide range of sounds).  This Marshall lets
    you drive the power tube to get that TONE without killing people.  I mic it
    to the board for bigger rooms and to control FOH mix.

    Right now I've relegated the 2101 to effects loop status because I'm using a
    Fulltone Fulldrive II overdrive pedal on the front end.  I do not use this
    Marshall's distortion channel for the most part because it is rather harsh
    and nonarticulate (like most modern high gain amps).  However, with the
    clean prevolume on about 3, the master on 10 I get wonderful, full clean
    tones.   The 2101 digital effects sound beautiful.  When I engage the
    Fulldrive, I get nice crunchy/bluesy overdrive.  I go to the "boost" on the
    Fulldrive and go into Allman Bros territory.

    The other reason the 2101 is now in the effects loop (ie., I don't use it's
    analog section or distortion) is that I've found going straight into a tube
    amp front end, even with the Fulldrive, lets the guitar volume control how
    much drive you get.  In this way, I can set the guitar volume at 6 or 7 for
    crunchy rhythm sections, then roll it up full for the leads and fills.  The
    2101 tube preamp does not seem to respond this way nearly as well, and it's
    lost when that signal is fed into the amp input.  I've tried that "y cord"
    dual setup described in the 2101 Artist manual, with no useable results.

    The DSL201 is small, lightweight, easily upgradeable with alternate tubes (I
    like the JAN/Phillips NOS 12at7 and the JJ EL84s) and speaker.  The down
    side is you can't hook up an external speaker cab.  However, if you're mic'g
    to the board, the extra speakers are only for stage ears.

    Beware the DSL401 which is this amp's 40watt big brother.  I believe its the
    same basic amp with higher output circuitry, and therefore much hotter.
    Lots of folks have reported problems with the 401 (overheating causing
    traces to break, solder joints to fail, etc.).  The 201 get plenty warm, but
    no problems (I've had mine for 2 years, plenty of gigs, rehearsals, outdoor
    gigs, etc. and no problems).

    Sorry for the long post, but buying an amp is a big deal (at least to me)
    and thought this might be helpful.

      I'm considering buying a better power amp for my 2101.
      At the moment I mainly run the 2101 straight into the board.
      (I do small gigs for a living)
      But sometimes I like bringing my Marshall 4X12 to get some vibration if
    you know what I mean! ;-)
      I currently have the Marshall Valvestate which does the job but after
    hearing my stuff through
      a tube power amp I couldn't believe the difference in tone!!
      (this was just using a Fender Deville for power by-passing it's preamp)

      I don't need HUGE power, just something that sounds great & can do
    small/medium gigs with.
      Oh and for recording as well.
      There's a local who's selling a Marshall 9000 series or something.
      50 watt stereo tube for $300 CAD which is about $200 US
      He said it was an older Marshall?
      These any good, fair price?? I think he'll go lower too.

      Thanks
      Sean
