Not to be overly picky, but what's the value of the fuzzpot ?
Count the number of connections at 1 node [pick node 1 to check on], and note the polarized markings of the schematic of any components with a lead to that node.
Use the DMM to count the node connections on your board, observe polarity wherever there is a marking which 'doesn't turn around like TOT', ie if one side has an arrow or a line or a _ or a + marking...count it as as relevant as anything.
Starting at the battery clip node might be a good place, see that every node past a battery pole [note polarity] actually makes a connection to, or 'through to' the board...trace each side of the PS through whatever it goes through [shown on schematic].
Measure every resistor [they help set up/adjust DC bias], I used 470k instead of 470 in a few FF's.
