[QUOTE="marantz123, post: 793143, member: 16849"] Another thing here...if the supply voltage is AC, which i think it is, then you can still safely run the led but may notice some very fast vibration-like flicker at times but its not serious and hardly noticeable to the untrained eye. The diode reverse voltage rejection is sufficient enough and the led survives. Modified a 2215 this way using those 12v flex led strips. Another thing with the 41xx series is the power switch...they pack up and short out..its at least 40yrs old now.(posted a thread here abt this last yr) Vintage TV3 and TV5/TV8 switches work well here as replacements and are available locally at TV spares shops. Replace the switch to be safe. [/QUOTE]
