Why not? many amps have same kind of design, balanced output plus both balanced and unbalanced input.

Anyway, this amp looks really really nice. Quite stylish.

I vote that it is named after the A-10 Thunderbolt, not the A-10 Warthog.

Yeah, took me three hours of searching to find it :



I was wondering if Ray has add special things or cool stories to say about it.

You'd be getting out cheap!

Congratulations Ray, on another fantastic project. I certainly hope this amp makes it to the next NY meet.

Something for me to strive for...

I have designed and built preamps with single ended input and balanced output. It isn't hard to do and works great. I use output transformers to do it.

The A-10....

See the first post for more up-date...
Sorry, I have to do it in pieces as my time is limited....

Ray,

Is the preamp on this better than the preamp on the B52? I am mainly interested in the preamp capabilities of this amp.

Thanks.

unlike the B52 this one has a phase splitter and sends balanced signals from its XLR outs when SE inputs are selected. seems standard to so much other gear dating back into the 60's.

I don't understand what are you trying to say here...
In your first post you ask how is the SE signal converted to balanced, then you come with this reply to some else's question that has nothing to do with his question & try to explain or answer your own question in the previos post regarding the balanced output.

That sounds like that would be a good thing - no matter whether you select SE input or balanced XLR input, the preamp outputs balanced drive XLR to your amp. Is the 60's reference a knock on the A-10? I didn't understand.

EDIT - Okay I see Ray responded, confused as well.

right, it's not a fully balanced amplifier in the true sense of the term.

It is a full balanced ampliifier in the true sence of term & some more.
Please read my first post before reading some one else's theory & prediction.

Could the 6SN7 tubes not be mounted horizontally above the chassis......
Maybe the the single 12AX7 mounted on horizintally on the front panel....

just trying to visualise the warthog here

Ray, I do believe you could with a small tweak here and there get a 4-pin XLR in there for a dynamic headphone too. That would be sweet! Just a thought...
