[Premium-Rx] Wanted schematic for A8 IF board in HF-8054A receiver

[Karl-Arne Markström]

Many thanks for the HF-8054A manual files.
 
It now enables me to use a recently obtained 8A2 CW/AM  filter board in an HF-8054A,
where the 8A1 IF board was not fully populated with components.
The reasons for this are probably only known to the manufacturer.
 
By installing the new filter board, the CW selectivities now are 250 Hz and 700 Hz, which is a considerable
improvement from the previous 2,8 and 16 kHz bandpass selections.
 
Thanks again for all help from the Premium-RX community.

Uploads took a while but downloads should be quicker, it's the first time I've used Mediafire though so any problems please let me know.

Hello,

I am looking for a copy of the schematic for the fully populated
450 kHz main IF board A8 in the Rockwell-Collins HF-8054A receiver.
The same board was also used in other HF-8050 series receivers.
