Morley Power Fuzz Wah questions

[newperson]

Hello,

Does anyone know what the power output should be from the internal transformer?  This is the PFW original transistor based edition.   Early 1980's edition I would guess.

Does this help?

Thank you it does.  I could not find any information on the schematics from Tel Ray/Morley.  This one above has it at 28VAC, but has AV at 220AC.  I would guess the transformer would put out the same 28VAC on a 115AC model. 

One a side note, would there be any reason AC being grounded to the chassis along with the DC cause any difference in voltage readings?  Someone added a 3 prong plug with the earth ground put onto the transformer housing, which in turn goes to the chassis housing. 

Thanks again for the redrawn and clean schematics!
