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

Best regards,
Carlos
