Hi - I need to replace the Power Transformer on my Samson Servo 170 - it is marked "Dong 2828081300 DSA3 - I think the secondary winding is centretapped either 28 - 0 - 28 or 30 - 0 - 30 - but can you tell me what the current rating needs to be - the Bridge rectifier appears to be rated at 8 amp. Many Thanks Chris M

my friend resistors and diodes don't just go off your circuit without a real problem. those parts gave up because of shortage on your power section, i suggest that you check your power transistros first along with the diodes and resistors.

noisy transformers... hmmmm why is that making sound? the solution there is to dip the power transformer to a thick shellac varnish let it there for let's say an hour then let it dry for a day. then place it back in your unit and see if still sounds
