Bill,
Your asking me? I am the one that is confused. However, I think you hit the nail on the head. I thought it was something to do with Diodes. Thanks, now I can go see what a "bridge rectifier" does. Homer says "Doh!" and so do I! Doohh!!

Cheers,
Alan

Its a rectifier. You can make one out of 4 diodes or just buy one.

Hi there. I'm new around here, but have been browsing for some time. Well, I finally decided that I wanna hear how a tube amp sounds, so I built a kit amp that is available here in South Africa. Sounds really good and I'm enjoying it tremendously.

If anyone wants more details: http://www.artslink.co.za/mars as I am no technical boffin. :D

That is a really nice kit, the first time I saw the picture I thought it was home made. 600$ is real cheap for a tube amp these days, and considering the fact that it came with every thing, I would recommend this kit to anyone.

If you know how to modify power supply circuits you could use a tube rectifier and two 1N4007 diodes to make a full wave bridge. It looks really cool and works just as well as a normal silicon bridge rectifier, I'm not to fond of using diodes in my power supply, so I combine the two when necessary.

Bye for now ;)

Just want to find out: Would I be able to solder in a pre-out circuit into this design :worried: ? Want to send a signal to my active sub to aid a bit in the lower parts.

The easy way would be to do that with stereo to mono adapters.

But check the impedance, and drive requirements of the amps.

Thanks, but my amp is integrated and does not have a pre-amp out. I think I can make a pre-amp out, by tapping signal from my volume pot and connect it to arca connector to the back of the amp. Just hopr that the signal will be strong enough to get the active sub going.

Alan, That is a solid state full-wave bridge rectifier. Insert AC on the top and bottom connections and you will get DC with negative on the left connection and positive on the right connection.

They can be made with 4 individual diodes, or you can buy them complete in a package :)
