TFM 35 Voltage at TPs

Just a quick question:

What should be the voltage at test points 201/203 & 202/204 on a TFM 35?
Any help is greatly appreciated!
Thanks O:)

I believe they are like the M-1.0t at 0.5mV
It should sound like it isn't there!

Thank you Bill :)

201 was at 6.5mv and 202 was at 4.9 after settling, so thanks again.

Well, you are supposed to set those after turning on the amp from cold and waiting 2 minutes. They will drift higher after the amp continues to warm or be used.
