The ask dsavitsk thread

[dsavitsk]

I guess On / Off switch since the power supply is included on the PCB.

It's the impedance selector. The on-off switch is built in to the IEC, as is the fuse. This is for safety reasons so that the fuse can't be easily defeated, and when the switch is turned off, there is nothing past the IEC that is live. Also, the yellow caps block the high voltages, so the the front 4" of the amp is entirely low voltage.

No chance that you're forgetting the fact that the Hammond end panels already essentially have a shim built into the plastic bezel?

I think Doug means that the PCB sticks out by 0.5mm. If I'm not mistaken, the shim in the bezel is going to cover the slots, meaning it will stick out, too. Still, trivial in the scheme of things and Hammond just supplied us a couple of one-offs straight from the production line. We'll get them custom-machined and have them in good shape, eventually, I hope.

It doesn't take much to cut the plastic bezel to allow the board to protrude into the cavit it creates behind the back panel. Not that I've had to do anything like that before...

Yep - good point. That will certainly work.

[dsavitsk]

It's actually not Hammond's doing, as much as I'd like to blame them. The board fits in the case just fine, but the person who did the layout had the pot extend a tiny bit too far. Now, the intention was that the board would be just shorter than the case to allow for some wiggle, in which case things would be fine, but since the board and case are matched, a couple of washers will be needed. As Tom says, this will be fixed in the final.

That's the idea -- the parts cost is remarkably low -- $1 tube, which is still a secret for now , $9 OPT. The most expensive things there are the IEC and the Alps pot (unless you use Auricaps, I suppose).

well, not to mention the case so, surely you have a ballpark full kit number you could throw out in strictest confidences of the hallows of Head Case

ooh, gonna build this one, and it might even work afterwards

[recstar24]

Had a chance to check it out last night, as Doug stopped by with the amp, as well as his balanced solid state. I was really impressed, we spun disks all night and everything sounded killer. Considering what the parts count and what the total kit may cost, this is one sick of a deal for the sound that I was hearing.

[Beefy]

Brilliant. How long until we get some more details?

[luvdunhill]

looking for some beta volunteers?

[dsavitsk]

We will be, but we need to figure out the details of how that will work ... probably take a few days/weeks to get that organized.

[TomB]

Finally cased it up -





Note: Hammond supplied us with these special length cases "unofficially." Hence, the black endplates and unanodized extrusion.

Congratulations, that turned out to be a very good looking amp. Would love to listen to it one day.

[fierce_freak]

That's awesome

[Smeggy]

Very cool. I like that form factor, it has a look about it. I think mine ( ) will have to have a mesh top to see all the goodies inside.
