pl-51a voltages

Post by blas62 » 18 Mar 2019 13:56

Hi.

I have a Pioneer pl-51a and I would like to change the transformer to a toroidal one. In the service manual it does not indicate voltages or amperes. I have measured with a voltmeter and in the secondary it gives me 24v and in points 5 and 6 of the KWR-030 it gives me 19.5V. Are these values correct? I would appreciate it if I confirmed them and the amps, that for the fuse would be 0.3 mA maximum.

How many volts and amps should the new transformer be?
The primary would be 240V.

Thanks

If the original transformer is still good, I see no reason to change it, or modify things.
You won't benefit from such things.

Someone could tell me the voltages and amps of the secondary of the transformer and the power supply?
To see if they are correct.
Thank you.

No one on planet Earth knows the answer?

Hello
When changing the capacitors of the motor controller, a red wire has been released (it will be the positive one) and I do not remember where it was connected. Do not take photos. I would appreciate someone uploading a photo to repair it.
Thank you.
