Re: Can you wind your own Repanco DRR2 coil?
The Gee RF units are a source of a number of Aladdin formers.
I certainly wouldn't advocate dismantling a good example, but they are common and often turn up in battered or previously hacked-about condition, only really suitable for parts recovery. |

Re: Can you wind your own Repanco DRR2 coil?
Winding a DRR2 replacement on a dust-iron toroid could lead to too much coupling so no longer possible to short the LW winding for MW. I suspect that the only way to achieve similar performance (i.e. same inductance, similar coupling, similar capacitance) is to replicate the DRR2 design fairly closely.

Re: Can you wind your own Repanco DRR2 coil?
Dave,you are absolutely correct,I only did the MW section.
The attempt was to derive a coil with the same sharp tuning selectivity. I would undoubtedly have driven myself mad attempting to put all the extra LW turns on as well. |
