Title: Light Show - Right side input tube Torii MK IV
Post by Rivieraranch on 01/03/15 at 02:18:55

I found some nice Japanese made 1960's 6922 tubes marked Westinghouse. I found that the tube on the right side would have a light show on startup. This killed one of the tubes already. What is the culprit for this? I previously used some 1060's Tesla yellow label PCC 88's in the input positions.

I think the tube itself was the culprit.

Uncle Lon:

The tube from the left side was swapped to the right and it, too did a smaller light show when turned on. This right side has already killed one of those tubes. The tube that I first noticed doing the light show was started up on my Taboo and it did not flash at all.

So for now, I am back to the Tesla PCC88, which are not strained on startup.

Okay then Brother Jim. . . something is amiss, I suspect a solder weld to be honest. Maybe time for a trip to the mothership, sorry to say. . . .

Steve convinced me that perhaps it is a weak batch of tubes. I tired a pair of 6BQ7 in there and no light show. Also the PCC88 do not flash either.

The 6BQ7 do not perform well in the Torii at all. They don't amplify the signal enough. You have to turn the volume up really high to get anything out of the amp with these as inputs. While they might work in a Zen, these do not do well in the Torii
