Good progress today on the B-17A bass preamp prototype. As you can see from the pictures below the chassis is complete and the power supply is built. I went ahead and put the knobs on and tubes in the sockets so you can see what it will look like.
The power supply is in the enclosure on top, to keep it isolated from the preamp circuitry. Here is what it looks like inside.
The inside of the chassis still needs a few things, as you can see below…
The standoffs are there for the circuit board, so hopefully its just a matter of adding that and getting everything wired up. But this is as far as I’m going today.
For the next version of this preamp we have already chosen a different case which we believe will add to the appeal. But for now the next step is to make sure this prototype works and make any adjustments needed.
That’s it for now!
