Crackle just like cathode/heater leakage in one of the valves, but active test as perfectly good isolation . This crackle was present on first receipt testing but now with close-handling not the slightest trace - typical symptom of PbFitis , also can be similar "bacon and eggs" crackle . Any known problem area? hopefully not with the DSP chippery. ( just dealing with a Hartke HA3500 with pbfitis , but as 2006 a bit more excusable)
