orion,

Closest thing to a tube kit at the moment on here would be the thread called "6888 AM broadcaster with PCB". Just a couple of sources for all the parts. The holdup on the 12CS6 kits here is that we have no transformers available at the moment.

Bill

I have a stash of 25.2V CT 450mA RadioShack power transformers if they would be useful. Send a PM if you want to get one or more.

Orion,

If you want to try a kit with that tranny offer I'll send you a parts kit.

Bill

If you look back on page 24 at the posts by "dead short" it will reference a parts kit that he got from me. Life has caused deadshort to back burner this. Remember when that first girl caused you to forget about electronics altogether? Deadshorts are not as much fun as that. He and I are looking for someone to pick up the project. He will send the parts (he may have added a few parts) anywhere. That classic electronics guy on page 28 is offering up good iron for this which might help. Any one whose wife has thrown the stack of AA5 carcus out that was stacked in the kitchen, this is your chance to get even. Just put this project right on the kitchen table! I guess it will have to be first come, first serve. Newbies and Lurkers here is your chance. Just post pics of your build and your problems right on this thread.

The one I built years ago is still running fine.

Bill I'm not sure but I suspect from scratch, tube xmitt building has mostly run it's course... What I'm seeing now is questions about adding inputs and I-pod to their radios... Few seem to care whether it glows or not... Heck I have a LM386 in the house and a 6888 out back in the garage where I can't see it... I do know it's there cause if it stops I have to go see why(usually computer shut down because of power blip or it needs rebooting just because)..

I agree Tom. That is what I'm seeing too.

Bill

EDIT: I think 6888 did make a decade long run thanks to all your designs. Colins 6888 contest may have been the last flury of activity.

You mean all my hacks??? :lol: Norm should be thanked for the original 6888 design(and all those transfomer donations for the 12AV6/12CS6 Tx), without his expertise likely none of this would have happened... By now probably be a six month wait for the SS-trans kits... :shock:

Maybe I should get off my duff and build the screen modulated 6V6G xmitt I designed probably five years ago??? Doesn't perform any better than a 6888 but with four ST tubes it's looks are impressive... Note tubes pictured were just for mock up, it's much easier to fit big pin tubes through cardboard than octal type, though I did plan to use the 80 rectifier...

I think eventually someone will want to build one. I've got so many other projects going that I felt guilty holding on to the parts. If no one claims them, I'll build it eventually and post here when I do.

I like this box I got from ebay. Would be a good one for a transmitter.

I couldn't agree more! Also, along the way our cast of prototype builders keeping interest up. My interest skyrocketed with Mike Toon when prototyped Norm's 6888 on a thread. Then the ones who prototyped your concept designs and gave us threads and more. TIMO 6LE8, Mike Yancey 6GY6, the Leal/Bryant 12AV6/12CS6. I know that I'm forgetting some.

Calling all slackers! Time to start building just to prove that we have a few vacuum tube lovers still left out there.

Count me in Bill. My music must be squeezed through inner space. And mostly from vinyl. Some silicon is OK, but not in the audio path :wink:
