    It's not Po=25W, it just uses a 25W OT for full frequency response. That amp would run somewhere in the neighborhood of 8-10W @ ~10%THD. The overspec'd OT gives about the same effect as running a Hammond 125D.

      I've always dreamt of using one single ended This one in class AB2PP would be mad thought

          satamax,
          this is incredible, this must make a SE amp with at least about 50 Watt?
          But a quick check in the Internet said: it costs about 100Euro and OT and PT will be expensive too. this might be out of my finance range in the moment

          I changed my SE amp to an 6L6 output stage but i dont like the sound yet( i miss the sparkle) , it seemes to be louder than the el84 output stage ( though its the same OT) and worked in rehearsal quite good. i will have to tune it, but maybe its the character of the EL84 that i like and then i wont get it with an other tube, then i may have to go into the direction of el84 Parallel output stage, have you ever done such a thing? ( i only did it with 12ax7 in the preamp of my SE amp)

            Hi Rexdingo.

            Well, sorry, but i'm no guru or master or anything. Just a guitarmaker who had to turn into an amp modder. I've destroyed the first three amps i've touched. And i've repaired several since. Two hiwatts. An eko duke an Ac 30 A SC120. A SC 100. Two BF bassman a super reverb and a bandmaster. An original JMP also and a JTM60. Plus i've had of mine 1 Fender champ 25SE, a JTM60, a Boogie mark2B, 3 sound city L120 2 L100 4 PA50, two of which have been transformed into guitar amps. 1 hiwatt circuit and one into a MK3 50W (which never existed!) But since i've hung around ampage from 2000 or thereabouts. I've learnt a great deal. Actualy, most of what i know about amps, and i've gathered many usefull infos. Most certainly, this big tube has been showed to me by Ken Gilbert, while talking about the BAGA. http://ken-gilbert.com/tubestuff.html. And for parallel SE, the two ever SE tranies i've had whent to the dumpster along with my first sound city 120 when my grand ma decided to clean the house while i was at school in UK in 96. Never had spare cash to get another one since.

            Here's my best mod soo far. http://satamax.free.fr/mark3/

            Sorry i can't be of any more help.

            Bye.

              Hi Max, thats ok, no prob ( i will probably start a new thread for the parallel output tubes), i like Your attitude, but You mentioned an EKO amp, do You know any good Resources for these?
              i Have an Herald 4 under the table, the PT started to smoke when i plugged it in, this thing was a hybrid with transistor preamp and 2 x el34 tube power amp, the ot is good, a far as i can test. but i cant find any schematics for these.

              As for the Guitar making thats very interesting!
              I build several guitars before i got into electronics, since then i built 5 amps:
              - 18watt clone
              - Princeton clone with ef86 mod
              - p1 with ef86 mod
              - medianox ( my own design with one single 12ax7as pre and poweramp)
              - firefly clone with 12au7 selfsplit powerstage

                If you like the character of an EL84, why don't you try an EL34?
                "Enzo, I see that you replied parasitic oscillations. Is that a hypothesis? Or is that your amazing metal band I should check out?"

                  I've done a SE KT120 that put out around 25W or a bit more -- sounded great. Will likely build another one of these days.
