Two pieces of GU50 in PSE junction can deliver more than ~ 35W output power with very little internal resistance and low primary anode impedance (~ 1-1.25kOhms). With Shade feedback and a THD distortion criterion of ~ 2% output power can be greater than 25W (up to 30W!) so you should definitely try something like this.
