The four types of Transformers: Power Transformers: Power transformers provide power to the amp. Basically, the power transformer plugs into the wall voltage and turns that into the voltage your amp needs. The power transformer is not in the signal path so it does not directly affect the sound, but it can affect the sound as a secondary effect.. The power transformer is isolating the ac from the chassis but you have high voltages with nowhere to get a ground from except your body or those crazy switches I've seen on some old amps that connect chassis to the ac (hopefully neutral side but it's a lottery with a 2 prong plug) via a capacitor or even high value resistor.

Most commonly, there are two large transformers in an amp — The other besides the output transformer is called the power transformer — that is the one that is responsible for taking the wall current and transforming it into the DC power used by your amplifier. While the power transformer is directly responsible for areas like supplying exactly how much voltage goes to your tubes and therefore can affect the response or “feel” of the amplifier, it is the output transformer that can ....

The new output transformer will need to break-in over time, but all that's left now is enjoying your amplifier's improved tone! Remember that an amplifier's tone is the sum of all of its parts. The reason is that the power and output transformers are the heart and soul of a valve guitar amp. These are the most expensive components and the most difficult to replace or repair. Just a chassis with two good transformers is a real prospect, but even a previously working amp with an unserviceable transformer is a nightmare. A high powered Altec industrial speaker was maybe 25 watts, and top of the line Jensen guitar speakers were rarely over 15 watts. A vintage P10R was a whopping 9 watts! This presented a problem for Fender. His wide range, high fidelity guitar amps were driven by two 6L6s, which by mid decade had evolved into a 40 watt power plant.. I was fiddling around with a small power transformer the other day. I hooked it up to an op-amp with a bit of gain and a +-15V supply. I used my Boss MT-2 pedal for some distortion plugged into it and it sounds pretty decent. Re: Power transformer current, parallel SE 6V6 amp. 6V6 at 12-14W Pdiss makes 5+W audio output.
