Thx guys, Ive pretty much finished all the power supplies for circuits now, so once Ive got the PCB for the audio constructed and connected it to a relay then it should kick in with the flashing lights. Fit that along with the metronome PCB into the remaining support wall and then fit the disguised record panel Ive constructed over the top . . a cover fitted for the speaker . . then brick the whole lot up . . fit the window frame on the inside and put in the glass and covers and weld them in place.
