Shuguang is the manufacturer.
What I've gathered is PM relabels tubes. Ruby also relabels tubes. However Ruby is the only company I've ever seen with their name on the BHT tube, which is manufactured in China by the same company who manufacturers the STR. And the tube in this amp is 100% identical to the BHT from what I can tell. The middle two are STR. The outer two are BHT, relabeled as 6CA7 for some silly reason.
EDIT:
You know what... I wonder if they did this because Jason was running BSTR and BHT combo in his original modded Marshall the Evil Pumpkin is supposed to based on. Like he ran mismatched tubes so Fortin just decided to duplicate that in the production model for shits and giggles.
That sounds like you're onto something.
Sounds like PM labeled it wrong though.
So it's really running a bunch of EL34s?
