I'm installing a BoZ driver stage in a tube preamp. Here is an image of the module

And here is BoZ in the 4SUTea preamp. This has been very successful and drives my Intermezzo amp with its 400ohm DC input resistance with no problems. Plus I get the benefit of the tube front-end.

..........Remember both preamp invert the phase so if your power amp is non-phase inverting swap you speaker leads over.
The B1 is a Source Follower. A Source Follower does not invert.

This BoZ is not a B1. And this stage does invert but then so does the tube stage. In the end there is no invention from the preamp.

On further reflection this jFet stage could be the answer for those wanting to build a single stage tube preamp but need to drive into low impedance power amps. A tube preamp with a jFet buffer. Perfect.

I've started lurking and planning a BoZ build. I just love this build on a terminal strip!

I'm starting a collection of terminal strips for ptp builds. What's a good online source for terminal strips?
Where can I get this particular double row to duplicate this?

These are from Jaycar Electronics Australia. You can order online. Cat. HM3320 $4.85 for a pair.
