Title: Coils for BC-610 ??
Post by: W6TOM on August 23, 2015, 03:24:31 PM

 I got these coils at a few local swaps.

 The larger is 5 1/2" long and the OD is 4 1/4"

 The smaller is 5 1/2" long and the OD is 3 1/4"

 I'm told they are for a BC-610 transmitter, one set is labeled 14 - 18 MC, the second set no labels.

 I plan to give these to a friend who has a BC-610, can anyone confirm that these are in fact for a BC-610 and also the frequency of the unlabeled along what other equipment they may be for if not a BC-610? Thanks!!

T,


Some may use them for the Beasley 610, but its really a minimalist beer stein.

They look like BC610 coils. I sold some already and have a few left. Here are photos, maybe you can compare them to mine and read the printing on the ceramic. Or tell me which one and I can go read it to see.

The coils on the left in both pictures are for a BC-610. The coil on the right is for the BC-610 amplifier for the input grid circuit known as the AM-141. The coil in the second picture on the right is for antenna matching or a tuner since it has no center tap for B+.

Hope this helps?
