Hello again micsmeets,
Good to see you back, hope the vacation was up to your expectations!
In case you need an explanation, a re-capping job means replacing
some capacitors, namely the electrolytic and waxed paper ones.
There are at least two electrolytic capacitors in this chassis. One of them is
the big metal can standing between the 76 and 42 tubes, and the other looks
the same. Modern replacements will be much smaller. As a first step,
they can be installed under the chassis, and later on the cans of the
original capacitors may be emptied, and the replacement units mounted
inside. If a schematic is not available, two capacitors with 40-microfarad
capacitance and a voltage rating of 450 volts should work fine.
Electrolytic capacitor are polarized, meaning that they have a + and a -
terminal. It is most likely that the - terminal goes to chassis ground.
There might be one more electrolytic capacitor used as a cathode
bypass on an audio stage, but this is unlikely in an old radio like this.
It is important to avoid powering up the radio until the condition of the
field coil is checked, otherwise the electrolytic capacitors and rectifier
tube (80) could be damaged.
The waxed paper capacitors (or simply paper capacitors) are fairly big
cylinders (somewhere between a half- and one-inch in diameter,
and maybe 1 to 2-inch long). There may be a dozen or so in your radio.
All should be replaced with modern unit with the same capacitance. Voltage
rating of the replacements is unimportant as long as it is at least
as high as the original. Many of the values might be impossible to read,
which once again makes it desirable to get a schematic. The following

If you would like to meet me, talk to me or get me to have a look at the
radio, just send me a message and we can arrange something. Best regards.
P.S.: if you would let us know a little better the kind of test equipment
you have, your experience with troubleshooting and soldering, etc., that
would allow us to help you better.
