double mono SE

DjAlusiv · 8th March 2013, 09:58 PM

Was planning on building a double mono, parallel 807 SE amplifier. Before I start buying parts I was wondering if I am completely out of line lol.

my understanding is that Cary use paralleled SE's in their V12's , if thats what your asking.

Yea, I was only planning on using maybe 4 807's total between the two seperate amps. Guess this is a pretty basic idea, however I am new to the world of tube amp design so... Had a hard time finding parallel mono block SE amps in my searches. A lot of forum talk is that it is wasteful and lacks practicality.

Just have to have reasonably close matching of the tubes, really. And cathode resistors to act as load levelers. You lose a little power that way, but overall it makes for a good fit.

and an output transformer that can handle the current

Thanks guys. Sorry if I should have posted elsewhere. Mods, if this is fine I will go ahead and start documenting the build. I am going to have a lot of questions I think and this thread would be better used than making a new.

Thats documented quite well thank you! Perhaps I will have to bump up the tubage to 4.

Now if I can just use some quantum physics to turn all that wasted heat back into energy ...
