Ok will repeat the test on the good board. I also flipped the board over & measured directly
on the trafo output. Same readings. Can this be bought from ML ?
Guess it was just waiting to go down hence the volume issue that I experienced.

Thank again Bolserst.

Just to make sure, attached is pic of where you should measure the transformer on the back side of the board.

Andersonix was able to purchase a replacement transformer in the US a few years ago.

Wow nice Tyu so you recommend running the Odyssey at 4kv also.
Yes I was thinking about another variable voltage bias board. Saw a kit
just like you say with no signal sensing panel will be on all the time.
But isn’t it the same as power off speakers when not listening ? lol

Thanks again Tyu

Acoustat , sound lab...has ran there Panel Bias of over 30 on....24/7...right you well hear nothing any diff...but thay well sound better..
NO!....your panels only need an well only take 3k4 to high you can short out an kill the panels for ever.....the older CLSs2 were made to run
6k...but then thay drop to 4k8.....but you can drop the bias feeder res...from there 60meg to 20meg that well give better top end to the panels....being older panels

Yes Bolserst that’s where I measured . Also if I measured resistance no readings, dvm just fluctuates

So definitely a bad HV transformer.
Hopefully the dealer in Indonesia or Singapore can get you a replacement transformer or board for a reasonable price. If not, let us know and maybe we can locate a replacement here in the US and ship to you. Of course shipping cost won't be cheap...about $35 USD I would estimate.
