Comes with manual copy and my parts replacement notes.
I got this at a hamfest with intent of using for VLF rcvr. Bought a manual and started replacing parts (leaky caps, out-of- tolerance resistors, etc) even though it was working (having never used one, had no idea if it was working well or not but signal generator punches through). THEN, couple weeks ago picked up a Sierra 128-A (same gadget) at another 'fest and it appears this is the one to keep (rack-mount like rest of my station, solid-state, much larger freq range - DC to about 15 mhz, etc.)
Can send digital pix if desired.
If interested, make a reasonable offer. Buyer pays shipping. No extra charge to pack up and haul to USPO or UPS. If in central Florida, can deliver (Gainesville to St.Pete) for gas or beer.
