are these readings correct?

[tggzzz]

how about you guys stop being pedantic prats and answer the questions if you are able!?.

Then put some effort into writing your questions. You sound like a total pillock, which is why everyone is taking the micky. At least use a spell check for crying out loud.

Just so.

I have a lot of time for beginners who make mistakes, listen, think, and make new mistakes.

People that repeatedly don't listen (and usually don't think) are time wasters, a.k.a. time vampires.

sorry the ac input to the bridge is just about 19vac , The dc voltage when  the bridge dc output is connected to a filter cap is 40.5v,seems too high?.

Yes. It is too high. I would expect a DC voltage in the region of 25-27v DC.

Do you have a scope or another multimeter to verify the Fluke readings? You said you have an AVO8. Does that agree with the AC & DC readings of the Fluke?

Edit...as mentioned above, the Fluke 83V is an average reading meter, not true RMS. But even taking that into account, I would still only expect around 28-30v DC across the capacitor.

Could the primary be configured for 120V operation and it's run on 230V?#

EDIT:
I forgot the original poster said he measured the secondary voltage.

I suspect it's a measurement error, either due to the equipment or user.

Was the meter set to AC?

It should be tested on a known voltage first, to eliminate that possibility.

One possible reason for such high voltage could be non-sinusoidal AC output from transformer. May be a lot of high voltage peaks. Can you check transformer output with oscilloscope?
