big bob Posted July 12, 2012 Share Posted July 12, 2012 This is the start of my tube combo shoot out Amp = champ circuit with larger transformers. Cab= weber 2x12 with two 100 watt weber axis ( fane copy) 1st test Recto = 5u4 Power = Mesa el34 Pre= 12ax7 china The amp runs noisy with this set up... Background hum even with no guitar attached. Really early tube breakup, think 2/3 Fizzy/fuzzy sound works nice with the Dano distortion pedal. Hard to get a clean tone... No headroom really at all. Not as much volume as I would have expected. Test 2 Recto = sylvenia 5y3gt made in USA Power= Mesa el34 Pre= 12ax7 ma in china Link to comment Share on other sites More sharing options...
