RF choke source - UK Vintage Radio Repair and Restoration Discussion Forum

Does anyone know where these sorts of chokes are available now? This is 2.5mH and I need a few. Others of higher values with separate pile windings also required.

Modern equivalents are available, but it is nice to replace with appropriate types.

I've had a look on ebay and Amazon, but only found them on a site with minimum order of £20...

Thanks.

Ian

These sorts of once common parts seem thin on the ground these days, these would probably suit, but it looks like there are only a few left:

Thanks. I spotted those too. Quite expensive plus all that postage - though I guess post won't go up for more than one choke.

I think I have the odd one or two. Just looked and found one, will see if I can find the others and let you know.
