They can look real good but the CRT is critical. Looks nice & brite
with strong snow so this may be a good un. Usually you can change
one low level tube at a time & see slow improvement with each one.
They also all seemed to need the 41.25 & 4.5 traps tweaked.

Vertical/Horizontal Sync issues were always present on these sets - the >180K ohm resistors around the sync, horiz osc and 'GF7 tubes drift high, making the sync range quite narrow. We replaced 180K, 220K, 270K and 330K ohm resistors by the dozens. I wish I still had the RCA Goldenrod on the sync issues - lots of troubleshooting, but 90% of the cures resulted in a resistor change, so we shotgunned the resistors to save the trouble and the call backs...2% metal oxide resistors work fine...
Abe's corollary to Murphy's law: For every RCA with
n 5GH8 tubes,
n+1 will be bad...
