I read up somewhere about a defective 12pf cap on the plate of the burst amp tube, so I clipped in a 6pf just for fun, the hue shift was to the green now. I readjusted the phasing coil and was able to get a good purple to green shift. So I removed the 6pf and tried resetting the phasing coil again, this time I am able to get a decent purple to green shift. I have a feeling that cap has drifted, its a 5% and has a N220 rating which IIRC is a neg temp co-effiecent. I think the 1st time I tried it I just did not turn quite enough. Now when shifted to either extreme (green or purple) of hue the color gain seems to drop about the same. Not sure if this is normal using these 6ME8 tubes. I will have to check and see if my other Zeniths using these tubes do the same. Its not drastic, but you can clearly see the color gain increase when the hue is set to the middle (best flesh tone).
