[Terrence Harvey]

 All;
     A belated check in to the Roll Call of earlier this month. Still operating my Collins equipment to greater or lesser degrees as per below.
Equipment on hand.:
R-392, Collins design and  build, in need of alignment/possible repair due weak receive. R-390A, EAC 1967 contract jn above avg condition and workingR-390A, Teledyne 1962 contract, avg condition and working*R-390, Collins 1951 contract, working poorly, bad audio hum and distortion.R-390, Collins 1951 Contract, disassembled but mostly complete. "Some assembly required" Missing Oldham couple slip disc for PTO. R-388, Collins 1950 Contract, working but m]needs some alignment/tweaking to get where should be.R-648/ARR-41 Collins SN 848, Dynamotor powered, some what working, but weak receive. Needs help. Good Condition. 
Have really appreciated the combined wisdom and technical expertise of the group over the years. My thanks to all. 
Currently working on the audio module of *R-390 above. Think may have a leaky C-608, which is 22 ufd @ 300vdc, Sprague P96 series cap (Vitamin Q?). clamped under the chassis next to 6082s. Can someone tell me the best modern replacement for this cap? 

Thanks in advance for any/all assistance in getting this 390 back running again.
Best,
