Philips B8X72A is a beautiful large table top radio.

No audio output transformer is used in this design. The work Bi-amp is prominently displayed on the glass dial scale. The schematic can be found Here at the Radiomusium.org.

As Received				Normal wear and tear.	Normal but perhaps not desirable.

			There has been some work.

	New Lamps	New frosted lamp
				Mix up some matching brown.	Touch up the little scratches on the back of the glass.

The front volume control has two tone taps. I removed and disassembled for cleaning.

Ball bearing	To flair rivet.
Scrubbed with a tooth brush and denatured alcohol.	Cleaning in the chassis did not help much.
Dial glass to cabinet gasket material.		Pipe cleaners to clean tone switches.	Inside sticker.

This is the finished radio.	"Fedelita" The first tone button selected. The HQ or High Quality insignia is illuminated and the front volume control functions.	The three middle tone buttons are labeled "Stabilotone" and the rear volume control functions. With "Dolce" selected, the bass control functions and the tone display's blue lamp is on. The Treble knob does not operate.
With "Forte" depressed, the red lamp illuminates and the treble knob is active.	With "Mezzoforte" both red and blue tone display lamps are illuminated and both tone controls function. Again the rear volume control functions.	Finally with the "Parola" button depressed the front volume control is again active and the Spraak/ Parola indicator is illuminated.

S16 is not peaking any where near its original position. on the left.

S16 The transformer on the bottom.

I moved one of the internal slugs to span both coils in S16. The adjustment slug will now go through peak. The slot is adjusted pretty much all the way in but the slug goes through peak at 155.5 Khz. And the reception is good.
