I've got a question for the electronics gurus out there. I have an old Traynor all tube head that sounds killer in it's sweet spot. Unfortunately for it to reach that sound it is very loud and my current accommodations wouldn't allow for that. The best information I can find from Traynor is that it's a 45 watt head. There aren't much in the way of distinguishing markings on it. What I would like to do is build a 2x12 speaker cab and insert some type of volume knob between the output of the head and the speakers so I can drive the tubes enough to achieve the sound I'm looking for and control the overall volume at an acceptable level. Can it be done? I would imagine I that would need a high power variable resistor, possibly a diode, and a way to dissipate heat in a way that would be quiet enough to not render it useless for recording purposes. I don't want to melt the transformer in the process. Any info you could give me or point me in the direction of some good resources would greatly be appreciated.
