The Hot Box August 30, 2018

This is the Hot Box in use at #BlueRoom #PrivateEar:

It allows you to plug a tube amp into the Hot Box instead of a speaker and then gives you a balanced output that you can send to your recording system. Not a new idea, but my hotbox is a little different inside hence it appears to sound better. One thing it does not have is a reactive load. I am not convinced this [having a reactive load] is a good idea. I have examined the reactive load of another box that does this and I think it is a gimmick and am not convinced that it will give you much, compared to the cost of the reactive components. I will build these units for others on demand, and you can try one before you buy it. Call me if you are interested!

Holy Grail August 8, 2017

This is a Holy Grail. Most players say it's a good reverb box. This unit makes a whiny hum. My guess is that all Holy Grails do that.

Except, of course, this one. Why is this one different? An original Holy Grail comes with all metal input/output jacks. As you can see, I have replaced those jacks with plastic Neutrik jacks. Now, why would I do that? Metal jacks make a ground connection to the chassis. Hence, we have 3 ground connections to the chassis: the input jack, the output jack and the power jack. This creates "ground loops." By using plastic jacks, I eliminated the ground loops. After that, I had to add a ground jumper from the output jack to the chassis ground. But not all ground points are the same! Grounding at the output jack nut or the AC ground created noise. So I added the green wire and grounded at the voltage regulator on the PCB, as you can see in the picture below:

Fantastic! Now this piece of Holy Sh** has stopped whining and sounds Wholly Great!
