Help Wanted:- H.S.A. AERIAL AMP.

[speedbird9274]

Can anyone help me with info on the following item:-

H.S.A. Ltd Manchester series aerial amplifier,

serial no. B3-70-68 Issue no. 3 DWG no 16207A
Last tested 17-11-71 by BGA 316.

I know its a "big ask" but does anyone remember working with the above type of equipment ?. If so can you answer the following questions:-

What it the input (operating ) voltage
What is the frequency range
Is the amplification on receive only ( or TX too )
If it amplifies on transmit, what is the max input power
What is the gain on RX ( & TX )
Where can I find more details ...circuit diagrams...manual

I bought this item at a Radio Rally to use as spares, however upon examination found the unit to be in excellent condition. It would be a shame not to use this amp. for its primary use so any help would be most welcome. THANKS GUYS.

Hi, I would suggest that you look at the input side and see what type of in-built transformer system it has...if its a lennear amp for use in aircraft it will most definately be 24v...
