dan670844 Posted January 7, 2011 Share Posted January 7, 2011 (edited) Arrgh as usual I didn't read the post properly, this amp isnt for me then! But if I had to choose an all valve design for live work it would be 200watt output KT88 output transformer that is as linear as possible Baxandall Tone Stack with frequencies set appropiate for bass then you have some hope of controlling the mid range and cutting your bass boom if required, maybe the treble is set at 1-2.6khz to control harmonics, Bright pot? 5khz to control attack dynamics!!!! Mid shift circuit to pull the q down at around 400hz self biasing a must a push switch bias would be great Tone stack bypass just for me............ adequate cab ventilation 100 year warranty Free exchange output valve service And a sensible plate voltage so not right of the edge of oblivion to assist with reliability An automatic NO!! sensor when someone tries to move it when the tubes are still hot A decent instruction manual which informs the purchaser how to look after it, and not assume anything as most people who now use this stuff were not born when valve equipment was the primary amplifier equipment for bass Edited January 25, 2011 by dan670844 Quote Link to comment Share on other sites More sharing options...
Mr. Foxen Posted January 24, 2011 Share Posted January 24, 2011 Any news on this? Was fiddling about with my Burman, and thinking, the option of plugging in before or after a gain stage is kind of cool, as is the three gain knobs, so you can control the gain at various stages of the preamp. Keeps it all valve, but will make the knob twiddlers happy. Probably bit much for bass amp purposes though. Quote Link to comment Share on other sites More sharing options...

We all agree that it's got be good/innovative to appeal to the discerning user. The blank sheet we have started with has now become a wish list of specs that has been influenced by many of the posts on this thread. So the next phase involves seeing how these ideas can be made in to reality via design and/or parts sourcing. When things get more actual than theoretical I'll be able to report further.

charic Posted January 25, 2011 Share Posted January 25, 2011 Most useless invention voice controlled bass amps!! "Turn UP" amp turns up "Turn UP" amp turns up "Turn DOWN!!!" amp can't hear you now so does nothing "I said TURN DOWN!!!!" amp does nothing Quote Link to comment Share on other sites More sharing options...
tremblap Posted May 22, 2011 Share Posted May 22, 2011 Where is this project now? Here are the couple of important points from the thread for me Low noise design Thermostatic fan High impedance input Two parametric eq Also I have seen guitar amps with two power output settings, this coulb be a neat option for studio vs live uses My two cents Pa Quote Link to comment Share on other sites More sharing options...
tremblap Posted May 22, 2011 Share Posted May 22, 2011 Forgot to say that 110 220v switching is essential Pa Quote Link to comment Share on other sites More sharing options...
