Akai M7 monoblocks
Just completed this Akai M7 recap and conversion to stand alone monoblocks. This is the second conversion I have done, its easy.
Tracker-x mods with BmWr75 updates for clarity.
It went well and both amps sound clean and quiet
One meter does nothing
One meter pegs out max when the amp reaches operating temp
I did not check if these meters worked prior to doing the conversion to monoblocks as the deck was in miserable condition
I checked all resistors
I am trying to understand the meters in order to try to get them functional?
I know they probably can't be perfect but just understanding them might help me out
I think the twisted blue wires are the lamps 6.3v
There are pots to control the 6.3v and the 5.7v off the transformer
I tried disconnecting the red wire but the meter still pegged out
I could bypass the meter white wire that goes to the speaker out plug
I could also pull both meters and swap them to see if it is the circuit or meter
Which wire is the supply side of the meter?
