Title: what is the 24 volt equivilent to the 6146 tube? Post by: Sam on May 12, 2007, 07:09:29 PM I would like to find the number for the 24 volt version of the 6146 tube. TNX, 73' de aa8wl, Sam ( I am looking for this because I was informed that the 24 volt version can be used to replace the 6000 tube in my T-368 if I cannot find a 6000 tube)

7357 is ruggedized 6159A. That's the numbers I came up with for a 6146 "24" volt variant. Title: Re: what is the 24 volt equivilent to the 6146 tube? Post by: KB2WIG on May 12, 2007, 07:30:59 PM 6159B 26.5V

Title: Re: what is the 24 volt equivilent to the 6146 tube? Post by: k7yoo on May 12, 2007, 10:07:07 PM actually a 25AV5 tv tube is a better choice. The 25AV5 is almost a direct replacement for the 6000. No socket rewiring & no plate cap. Look up the specs and compare them in the old GE tube manuals. If you change the filament voltage the 6AV5 is OK

The nice thing about the VFO of the T-3 is that the filament line for the 6000 tube is separate from everything else. So you can change out the filament transformer and use something instead of the 25~26 volt versions. Eric, WB4VVI(SK) shared this with me. He also indicated that the 6000 tube is nothing more than a glorified 6L6 with some pin changes. He seemed to believe that someone at Raytheon wasn't getting enough government contracts.

I have 2 6000's left over from my T-368 days. I would let one of them go to put that rig back on the air. I had two of those boat anchors at one time. The 6000 wasn't that hard to find back than. I would be interested in trading for a tube I need. I am looking for a replacement Amperex PQ 6922 for my tube condenser microphone. I want a new/ old stock tube and I'll trade a NOS 6000 for it. Can you help? Mike Title: Re: what is the 24 volt equivilent to the 6146 tube? Post by: Sam on May 13, 2007, 10:48:27 AM Hi Mike, if you have a chance give me a call and we can maybe work something out. I don't believe I have that particular tube you need but maybe I have something else you could use. If I remember correctly you live in around the Shelby area and I live in Sterling Heights so at least were close. My cell is 586-246-5184 and you can email me at my call aa8wl at comcast dot net 73' TNX de aa8wl

Good old Fair Radio has 6159 new old stock for $17. Mike Title: Re: what is the 24 volt equivilent to the 6146 tube? Post by: Sam on May 14, 2007, 11:49:11 PM I will be looking for the 6000 tube at Dayton if I have the opportunity to ride down there this week. I will checking on the weather as I may decide to run down on the motorcycle this time so I can't buy anything bigger than what would fit in the bags. Hihi Thanks for all the good info on the variations of tubes to use other than the 6000. The 25av5 tube sound interesting and I will look into this one. That sure would make it easier and less costly to replace than the 6000 at this time. I have read that the 6000 tube was built just for the T-368 and that would make a conversion to a more readily tube make sense. Thanks to all the good info and keep them coming. I hope to see you guys at Dayton, I will be the guy wearing the baseball cap so watch out for me. 73' TNX AGN, de aa8wl, Sam AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
