Gentlemen,

I am restoring a Grundig 5088 USA model and need some help with my first non-US radio restoration.  I am using a schematic found at www.rad-io.de  I have found it to be mostly accurate except for some of the audio frequency circuit architecture.  There are differences.

A friend of the family has translated most of the words.  So my questions are with the missing information below:

The resistors have the resitance printed on the body and a single color band on one end.  What does this band represent and what are the values of the colors?




I have identified three types of fixed capacitors; Paper (Papier), Syrofome (Styrofier?) and Ceramic/mica (Keromic?).  However, there are some paper capacitors that have a plastic like blue coating.  The schematic clearly identifies these as paper.  Is there more to these capacitors? Are they special (i.e., inverse temperature, resonant) capacitors?



Once I have replaced all of the paper and electrolytic capacitors (and the occational off tolerance resistor) RF alignment is next.   The IF frequencies (10.7/460) and the transformers are identified. However, there are plenty of other adjustments with no explanation.  Where might I find the alignment procedures? 

Please forgive me if this information is readily available on the internet.  If so, then please recomend an appropriate web site.

Thank you in advance for your time,
Paul.
