    I am looking for a new amp.. I am currently using a Hartke HA7000 and I am less the exstatic about it. I am running a Mesa 1516 cab and want a 400+ to run it but I have seen the 400s wich I dont know much about. I was curious to tonal differences and differences of power handling differences in the 2 amps.
     
  2. both are ~300 watts

    the 400 (which I prefer) was loaded with 6x 6550
    the 400+ has 12x 6l6

    I'm not sure I could tell the difference in a double blind listening test... but I have a preference for 6550 / KT88 power tubes.

    Really they are both 300 watts??? I was under the impression the 400+ had more power then the 400. is one of the amps cheaper to retube then the other? Also is the non adjustable bias an issue with the 400 like it is the 400+? Either way wont make much difference there I can get that modded.
     
  4. the 6550 can make 50 watts each. the 6l6 can make 25.

    check out prices, I just got 8 KT88 (can usually interchange with 6550) for $200.

    I'm pretty sure the 400 was set bias like the newer stuff too.
