Hello,

 

I have an alignment question about this radio. When I received it, the i.f. rejector circuit coil, marked '10' on the alignment point diagram, was not properly connected. I have reconnected it properly, and I want to make sure that it is adjusted correctly, since it appears to have been replaced by a previous owner.

 

I have completely re-capped the radio. This is the only alignment I want to attempt, since the radio appears to be working correctly, and all of the other coils and capacitors referenced in the alignment documentation are still sealed with the original wax or sealing compound.

 

The documentation I refer to is attached to this model on the RM website.

 

In the alignment procedures for the IF rejector circuit, it is stated that the signal generator should be set to 460 khz, radio set at 800 khz, and the signal generator connected to the radio 'via 10000 pF to Ka 4'. I can find no point in the radio schematic or alignment documentation that is labeled 'Ka 4'.

 

One of the capacitors which can be adjusted is labelled as 'K', but it is also referenced in the alignment 'sequence' documentation as 'K'.

 

There are two multiposition switches, marked 'K1' and 'K2', one of which uses position 4 on the 'a' side, but it does not seem to make sense to connect to this position with the signal generator for alignment.

 

Also, where would I connect to measure minimum output for correct alignment? Across the speaker output or audio output transformer?

 

Any help would be greatly appreciated. As stated before, the radio appears to be working well so I am going to leave it adjusted as it is until I get an answer here.

 

Thank you, Joe

Hallo die Runde,

Gary Kershaw aus Montreal fragt hier nach der Beschaffenheit der Verbindung zwischen Anzeigeelement und Drehknopf der Höhen- und Bassregelung (Abbildung).

Kann da jemand weiterhelfen?

Vielen Dank!

Greetings from Montreal,

 Does anyone know how the knobs connect to the indicators?  Is it a cord, a rubber band or something else?    Gary
