The “Loud!” is a low watt/low volt tube amp. The TDA7052B is a little hard to come by but I believe the TDA7052A will suffice. The preamp section is a Matsumin Valvecaster providing gain and tone controls. That’s then pushed into the amplifier IC and out to the speaker(s). The speaker positive and negative terminals must remain isolated from an enclosure as to not ground out the signal. The taper of the volume pot might be altered as well. In the end you get somewhere around 3watts, give or take.
