I just looked up 6LQ6 prices online - YIKES. Audiophiles have jacked the market up out of sight.

So early in my repairs I replaced the horizontal output tube and damper tube with what eBay claimed to be NOS tubes, plus the sellers noted they tested good too (vs just looking NOS). A few weeks ago I picked up spare tubes and swapped these out but did not see any improvement. I don’t have a tube tester so who knows, I could have bought weak tubes.

and yes, silly expensive.

We ran into quite a few borderline width cases always on rectangulars, using brand new H.out and damper tubes. Had to finally resort to putting a 82pf, 6KV disc ceramic cap across the damper (cathode to plate). This bumps the width out just a smidjin. Sometimes had to increase to 100 or 120 pf to get 'just enough' overscan.

The mod also has the effect of lowering H.out cathode current slightly (good). But it also reduces HV slightly, requiring bumping the HV adjust up a bit. So there's no 'free lunch'. The usable value for that cap is no higher than 120 pf.

Assume something like this should hold up to replace the horizontal AFC dual diodes: https://www.mouser.com/ProductDetail...R3IQl24Q%3D%3D
