Trial another tube(s). Some examples are simply noisier than others due to close proximity of cathode to filament, which doesn't show up as a short. Even swapping push-pull pairs pull to push ala musical chairs may help null noise, so trial that too. IOW the culpret could be a particular tube rather than the circut.
