The tingle sounds like bleed resistors. Meter it out and see how many volts and that there is no amps. I have seen them measure as high as 80 volts but no amps. (Should be only a few milliamps max). Unsolder the primary transformer leads and measure between the transformer primary and the chassis. The reading should be very high 500k , 1 meg ect.
Like Electronic M said that black stuff looks like Corona dope and I wouldn't be concerned about it.
As for the anode cap, consider yourself lucky that you have one that comes off easy. Some are difficult. As for no spark at discharge. In 30 years of servicing TV's I still have never seen one spark, but I still discharge just to be on the safe side. This is not the issue.
At both rectifiers and check the ohms of the secondary windings you're looking for 12 ohms between the points shown on the schematic. Also 70 ohms at the choke.
Check the polarity of all the electrolytic caps you've replaced. Check that nothing is touching. Then start checking DC voltages with the set on starting with the rectifiers and move forward.
