Can anyone give me typical measured marshall 1959SLP bias AC winding output voltages? I could use it, please.

Thanks!
 
If you're referring plate voltage, my '87 SJ is 480 volts. The early 70's SL "alumi" models exceed 500 volts.
 
Thanks! Though not looking for plate voltage but bias voltage. PT's provide a low current AC voltage winding for bias and I'm not familiar with the rating on old SLPs.

I looked at some reissue transformers on google and saw that a few of them that offered it as an option typically had 98V non center-tapped. I'm running with that value for now.
