Had a guy bring me a little Magnatone Starlet he needed help on. He attempted to put in an isolation transformer in it. Looks like he's got everything wired up correct but it's dead. No pilot light and heaters don't glow. (Note this amp uses the 35w4 rectifier)
All the grounds are now tied together at Chasis ground and the ground on the cord goes there also.
One of the outs of the ISO tranny go to ground and the other to the hot lug of the Pilot light.
He's removed the 270ohm and .05 cap from underneath the filter caps, then installed new 2 new filters tied to chasis ground.
I know the bulb is good. I've got 140VAC on all my heaters but they won't glow.
I've never had to tackle a iso tranny but it can't be that tough. I'm probably overlooking something obvious.
thanks in advance!
