3C24 really is a fine output tube...

[aldovan]

Friends

I finish my 3C24 amplifier project.
This tube really sound fine. My amplifier use a 6N6P tube in input, a BU208A power transistor in emitter follower for driver direct the grid of the 3C24 tube.

Cool..

Looks impressive, especially with cherry red plates. I was going to try building something with the 3C24 but the output level is a bit low for my speakers.

Nicely done !

What is that music it was playing in your video ?

 

[el156]

Yeah !
I remember using the BU508A in tv SMPSa long time ago!
The tubes look nice....

 

[el156]

Sorry BU208A......

Very nice Aldovan. I have seen that tube from time to time and always thought it would be a cool tube to build around. Do you have a scheem?

Congratulations!! I also have had my eyes on this tube but never found a schematic worth trying, care to share?

Best

It´s Rolling Stones...I not remenber the music name, I will verify...

Schematic

Very nice Aldovan. I have seen that tube from time to time and always thought it would be a cool tube to build around. Do you have a scheem?

Yes, I have the schematic...
This project is mine, them can can need some otimizations...
The BU208A do not is the more recommended transistor,you can use a more "HIFI" type...

What about damping factor ? I dumped my 3C24 breadboard , even with cathode feedback the bass was one-note and stodgy

I do not use feedback... The bass is good for my ears, see in the video...

Well, this just proves that I only know one or two songs from Rolling Stones I really like the intro and I'd like to use the same song to test my gear so I'm eagerly awaiting your reply.

The CD is the VOODOO LOUNGE and the music is THE WORST.

Thank you aldovan !

Aldovan,
I have some of those 3c24's, and was wondering if you could share a schematic if you have one...
By the way what is the primary load R of your opt's.
I am hopeing that I have something to make them fly.
Cheers,

Aldovan,
After further research, I found what I was looking for. Your amp sounds great by the way.

Heat dissipators on 3c24

Where did you find your heat dissipators for the grid and plate connections on the 3c24's?
I have a few 3c24's and would like to give them a workout, but I do not have dissipators to make them run cool at this time.
Any info would be greatly appreciated.
Cheers,
mltube

 

[Gluca]

they are made of unobtainium ... I spent months looking for eimacs plate/grid dissipating caps

 

[db!]

Heat dissipating connectors can easily be made if you have/know someone with a lathe. All you really need is a small hole drilled in a piece of aluminum stock. If you want to get fancy, you can cut some fins too.
