Ron, It is the "KKMoon" brand that can be purchased on Amazon for around $60. I used it today to align the 16X, and it made a good job of that, once I had become familiar with the controls. It is a bit noisy - creating a bit of out of band "hash" that could be heard when tuned away from the generator frequencies. For this work, it doesn't matter. O/P voltage can be adjusted from 5mV to 20 V over two ranges - this is a separate setting.

Anyway, the 16X has seen a first pass at alignment. It was pretty close, but did benefit from the procedure to get the dial reading accurately, and get the last ounce of signal. It also verified that all the bands are working. Reattaching the dial beforehand, I realised there was no procedure for how to set the dial to the tuning cap, so chose to set the cap at full mesh and align dial so the lower limit line coincided with the shadow pointer. That seems to be a good method.

I left the set on for a good while during and after the alignment and it was working beautifully. With the speaker turned right side up on the bench and facing me, music had very good depth and presence, and voice programmes were very clear. We almost forgot we were listening to AM!

Next: make a reproduction "Echo absorbing screen" back and reassemble into the cabinet.
