No sync on RCA KCA118A 17" B&W portable.

[farmradio]

Hello folks. Got a 1950's RCA B&W Model 170P034. Using KCS118A chassis. It plays well, except there is NO sync. The voltage on the screen & plate of the 6AW8 (Video output, & sync sep. are off a bit plate is too high, & screen is too low. I have a scope pic. of the 6AW8's video output plate. It does not look good to me. Swapped out the 6CU8 sync amp., & the Vid. out, but no change. The pulses on the plate of the 6AW8 do not look good either. So I'm wondering if those couplates are known in these RCA's like Philco to be a problem. Evey resistor tested is in range. Replaced some caps in the area, again with no change. Don't want to over-troubleshoot, but it's something strange. No sync pulses for both sweep oscillators. Just freewheeling along. Anything come to mind on the KCS118? Thank you.
Cathode reads 4.4V (according to SAMS should be 1.5), 4.6V on the control (SAMS shows .8V) Plate reads 175V, (should be 80). Screen reads 80, (should be 180).
