Title: 4-prong bias plug for Thunderbolt Post by: wa2dtw on January 29, 2006, 02:54:41 PM Hi
Does anyone know where I can obtain a 4-prong plug that fits the bias jack on the back of the Thunderbolt? I thought I had one, but the prongs are too thick. Many thanks and 73 Steve WA2DTW Title: Re: 4-prong bias plug for Thunderbolt Post by: w3jn on January 30, 2006, 06:55:13 AM post a photo, many of us have tons of odd connectors in the ol' junkbox. I've never had a T-bolt so I wouldn't know it if it bit me.

Here it is. I hope it works. 73 Steve Title: Re: 4-prong bias plug for Thunderbolt Post by: wa2dtw on January 30, 2006, 02:15:22 PM The dimensions, to the best of my measuring, seem to be pins 1-2 3/8" (or 80mm?) pins 1-4 3/8" (or 80mm?) pins 3-4 3/8" (or 80 mm?) pins 2-3 5/16" (or 60mm?) Thanks again and 73 Regards Steve Title: Re: 4-prong bias plug for Thunderbolt Post by: w3jn on January 30, 2006, 03:10:01 PM Looks familiar, I'll check the junkbox tonite.

Lots of time you can find the matching mike with the five pin plug on it at a hamfest. If you line up the five pin plug with your 4 pin socket, you can see quickly which pin to cut off. Lafayette HE-15, HE-20A/B/C, HB-111, 200, 222, 333, HE-35(I think), HE-45 series all used the 5 pin version. The 3, 4, 5, and I think there was a 6 pin version were also used on some 50's and 60's audio equipment.
