Philips Pionier V4a restoration

Hello everybody.
I present to you the restoration of the Philips Pionier V4a.
It was in a very bad state, but with a lot of work and care, I managed to save another radio.

What was done:
Replaced all tar capacitors.9 replicates were made.
The 4 mica capacitors of the FI were also replaced.
New electrolytic capacitors placed inside the old ones.
8 resistance replicas were made.
The power transformer has been rewound.
An IF coil was repaired.
The insulation of all wires has been replaced (or almost).
The volume potentiometer was repaired.
The speaker grill cloth was replaced, as well as the protective cloth.
Replaced a valve holder and changed the holder to the original AZ1 valve. There was an 80.
Cleaned all mechanical parts and replaced the quadrant wire.
...Uf...

Hope you like it

Carlos

What a rat's nest of wiring that radio has! Well done, looks like it took a lot of work!

Carlos,

Nice work,
What a big project it was with a good ending.
You had lot of fun with it, even rewind the transformer.
All looks new now and ready for next 80+yrs.

The V4a is a strange one with the layout of components like this.

Thanks for the story,
Maurice

Hi Carlos

Brilliant job!

I think beige knobs will look very well on this radio.
They'll be in the post tomorrow.

kind regards, EJ

Well done Carlos! Perfect job performed...
Not everybody knows that for a long time this radio was not for sale,
but for rent only. Therefore the back cover could not be removed without
breaking some sealings; the renting contract was very clear about that.
The original tubes had special markings. Sealings broken? Game over...
