Default Re: Philips BX281U20 valve radio

the serial number starts PL if any help.
Well I managed to get the chasis out what a nightmare the tunning dial well they have riveted 3 of the pulleys to the baffle board then the side pulleys had to be unscrewed as attached to chassis with dial and dial bar. The front of the pulley has a spring attached one side but other end free not sure if it's supposed to be like that as I know nothing about their construction! Now I think the hardest part for me is actually re doing the pulley mechanism so may need someone on here to do that for me paid of course.
As you can see the underside is just packed full of components making access incredibly difficult but doable. Top of chasis quite easy thank God but I think this one is going to take some time especially cleaning. The silver foil internally needs replacing easy enough. Speaker needs a clean.
Speaker wire well two sizes one normal 28awg the other which goes to output tranny like old cloth cable must be 18 or 16 awg!!!! Bit ott if you ask me.

So I don't think loads will need replacing underside some caps maybe the odd resistor.

Not sure what base it's on but on valve base is two pieces bakerlite sandwiching metal plate directly below the valve metal locator lug Any ideas on that one again not seen that before.

Anyhow be good to see if I can getting looking spick and span.

Attached some picks for you all.
