ENI Verteq VNA-1987 info

Looking for operating info on an ENI Verteq VNA-1987-21121 amplifier.

Operating manual, schematics, anything you've got.

Yes, I tried Google, and it wasn't my friend on this one.

Thanks and 73--

ONly info I could find was that the amp works from 35kHz to 2.9MHz. I can't get mine to work either.

If you're just trying to get it to work, there's an interlock, pins 14
and 15 on the rear DB15 connector -- you need to connect pins 14 and 15
to get the amplifier to work.

Look for VPA1987

DB15 pins--

1  -- max pwr ttl output, 0V = normal, +5 = max power
2  -- reverse power - DC voltage representing reverse power
3  -- forward power - DC voltage representing foward power
4  -- overheat ttl output, gnd = normal, +5 = overheat
5  -- external gain control, 1 - 10 VDC
6  -- GND - chassis ground
7
8  -- ext bias control - +15VDC for use w 10k pot to pin 5
9
10 -- leveling control. NC = unleveled, GND = leveled remote control
mode
11 -- load power -- DC voltage representing forward power
12 -- NC = load power leveling mode, GND = forward power leveling
13 -- +5VDC
14 -- interlock
15 -- interlock

Thanks Arti, got mine on ebay, verified the rf portion works fine and will try the db15 interlock tomorrow, but I seem to be missing two ic's on the control board so I'm not too optimistic.

I seem to need those two ic's to get the meter to work and to run the input thu the control board. With the two db15 interlock pins connected I get a brief output when I turn off the unit. I'm guessing I'm missing two lf387H ic's.
