Well--the first thing I would check is to see if the 3.58MHZ osc. is running--when you lose color. It most DEFINITELY sounds like either the crystal itself, or maybe a cap or such in it's ckt. I also would get a voltage reading on the plate and grids of the burst tube--and any in the ckt. with the crystal--when you DO have color--and THEN again--after it goes away. You might find a big discrepancy, between the 2 conditions.
As for "trickle current" in this set--the answer is NO..this set did NOT have any sort of instant on ckty--so there should NOT be any current drawn by it--when switched off. If there IS--then SOMETHING is not right--such as a leaky line-isolation cap-- and MUST be looked into.
