Later models of the AR-88 had SSB reception.

How about a nice picture of this excellent set?

I recently acquired an RCA AR-88.  No manual and I got what was available
on BAMA and alot of information on the WWW.

I have a copy of the AR-88 and CR-88 manuals.  They are adequate but I
would like to have better schematic copies and pictorials.

My receiver has been modified.  The visual inspection shows that the 1st
RF, 2nd RF, and 1st IF amplifiers tubes/valves have been replaced with
717A's.  I haven't looked to see if the screen resistor values have also
been changed.

The only documentation for the 717A change that I have was  changing the
1st RF amplifier and adding a 10K resistor in the screen voltage path for
that particular tube/valve. That was via GW3LJS.

Anyone have any information on the AR-88 modifications available.  I saw
something about an SSB modification but could not down load it.
