[ForSale-Swap] Need Ameco PCL information

[Philip Atchley]

Hello
I have an Ameco PCL Nuvistor preamp coming in the mail.  Does anyone out
there have the instruction sheet for this unit that they could scan and sent
me as an attachment?

The BAMA site has the instruction sheets for the the PCL-P (internal power
supply) version, which I downloaded and printed.  But, I intend to operate
the PCL off the accessory socket of my receiver (Hallicrafters SX-71).  The
B+ output on that socket is 310 Volts.  IF I remember correctly from past
years, if you run much over 150 VDC on the PCL there is an internal
dropping resistor that MUST be changed to prevent short Nuvistor life. I
need to look at the instructions for that resistor.  (Yes, I know Ohms Law
but to apply that you must first know the nominal current draw)

Now, I could rewire the socket on the SX-71 to feed the regulated 150 VDC
from the VR tube to the Pre-amp, but think that is overkill.  And, it may
just draw enough current to keep the VR tube from firing.  BESIDES, Since I
put so much work into restoring it, I'd like to keep the SX-71 unmodified.
