[stonehome]

Thanks Jeff. I'm only on my first cup of coffee.

Hello All,

I have received my RTX6001 Audio Analyzer today!
See the first analog loopback tests here:
RTX6001 out-of-the-box initial tests

I'm very happy with the device. Now I need to test it with my MAC and REW software, as I've got no Windows-based computer in my lab right now.

Cheers,
Valery

Too bad I missed this opportunity.

Finally received my transformer yesterday, after it got stuck at customs for missing information... Started to work on the wiring very late last night and decided that 1:30am was enough!

I should be able to finish this tonight and start testing the IPS and OPS later this week. Can't wait!

The water hammer analogy is a good one as it fits nicely with my contention that mosfet outputs are better because the turn on / off region is much softer then the .65v base - emitter junction, therefore less likely to generate high frequency spikes.

Hi Thimios,

I have ready to test the Vertical CFA and Tubsumo but I also have PCBs for AX-Deluxe and X4-VFA which will be assembled in the near future.
