Premier B-160 Club Bass. EF86 input. want to double check some values on schematic

[SoulFetish]

Got in a Premier B-160 Club Bass. Someones already been in there to make some changes, but didn't do any work in order to bring this amp up to modern safety standards. I can't tell what has been changed and no luck tracking down an official schematic. I re-drew this from a what I could make of a hand drawn version schematic of this particular version. If anyone is familiar, take a look at this to see if there are any errors. 4.7k on the plates of a 12AX7 seem like a very low value load resistor, but I'm not familiar with the circuit.

**edit: updated and corrected schematic below**

I don't know why anyone would take the time to open it up and not clip out the polarity cap and install a proper bonded 3-wire mains plug. The customer complained about experiencing shocks on occasion.

Those plate resistor values aren’t even close. I’m going to make some changes and put the accurate values are retrace the schematic. I couldn’t find a reliable source for this schematic in searching for hours, So I may as well do it while I have it

There is 1 hand drawn floating around, i have it as a pdf file. I have this amp but it has a 6ab4 for the input. Premier schematics are all missing and the ones you do find there will be 4 different ones plus the amp you have on the bench. Here is my version i have with serial number.

Thanks Mozz! Yeah, this was helpful to use as a guide.
The hand drawn on you mentioned is the one I copied to create this one. That was the only one I could find for the EF86 version. It contains errors, so
I edited and corrected some of the mistakes, in this version:
