Todd	Re: Is it possible to pull 2 of the 4 power tubes in a Traynor and cause no harm to the transformers? First, what type of Traynor? Just pulling two output tubes doesn't necessarily "work". You also need to change the output impedance by a factor of two because you're taking away two tubes. Same is true of a Marshall else you have a output transformer mismatch. Traynors use Hammond transformers for the most part which are far more durable than anything Marshall ever used so initially I would say you're OK to pull two tubes. BUT, I would half the output impedance as well (cut one of two 8-ohm speakers in a 2x12" cab for example). Let us know what model you're talking about and somebody can chime in with personal experience. TJK
